    The supply and widespread use of diamond grading reports can, when properly understood, enable even those without professional skills to produce valid comparisons between several stones, and thus make more informed buying decisions. Reports is an important tool that may help you understand differences affecting price. But we should caution happened permit them interfere with everything you like or really would like. Remember, some diamonds are incredibly beautiful while they don’t abide by establish standards. Within the end, make use of your own eyes and get yourself the method that you such as the stone.

    A person who was attempting to decide between several diamonds. Her husband wanted to buy her the stone with the best report, but she preferred another stone which, according to that which was around the reports, wasn’t of the same quality. They decide against the best diamond and acquired one that made her happiest. The biggest thing is they knew exactly what these folks were buying, and paid an appropriate price with the specific blend of quality factors. In other words, they provided the best choice. The reports gave them assurance as to the facts, and greater confidence that they can knew the things they were really comparing.

    Incorrect use of reports can result in costly mistakes

    As important s diamond grading reports can be, they can also be misused and bring about erroneous conclusions and expensive mistakes. The important thing to having the ability to rely on an engagement ring report, and having confidence with your decision, lies in understanding how to learn it properly. As an example, an internet to make a decision between two diamonds associated with diamond grading reports, buyers often decide by comparing just two factors evaluated about the reports, color and clarity, and think they’ve got developed a sound decision. This is rarely the case. No-one can make a sound decision according to color and clarity alone. In reality, when significant price differences exists between two stones of the color and clarity because higher priced stone, and quite often it’s not at all the higher value. Having the same color and clarity is merely part of the total picture. Variations price indicates variations quality, differences may very well not see or understand. With round diamonds, the info you will need is about the report, nevertheless, you should realise what all the details means simply uses make valid comparisons.

    Anything of caution: Tend not to buy something relying solely on any report without making certain the report matches the diamond, which the diamond continues to be inside the same condition described. Always seek a professional gemologist, gemologist-appraiser, or gem-testing laboratory to ensure that this stone accompanying report is, in fact, the stone described there, understanding that the stone continues to be within the same condition indicated around the report. You’ll find instances in which a report has become accidentally sent with the wrong stone. And, sometimes, deliberate fraud is involved.

    How to read diamond jewelry grading report

    Look into the date issued. It is very important to check the date about the report. It’s always feasible that the diamond has been damaged because the report was issued. This sometimes occurs with diamonds sold at auction. Since diamonds can be chipped or cracked with wear, you need to check them. As an example, you could possibly view a diamond that has a report describing it D – Flawless. If the stone were badly chipped following your report was issued, however, the clarity grade could easily drop to VVS, and in some cases, lower. Obviously, in this situation value would be dramatically reduced.

    Who issued the report? Check the name in the laboratory issuing the report. Is the report coming from a laboratory that is known and respected? Or even, the information about the report may not be reliable. Several well-respected laboratories issue reports on diamonds. Regardless of which report you happen to be reading, all provides similar information, including:

    Identity with the stone. This verifies that the stone can be a diamond. Some diamond reports don’t make a specific statement about identity because they’re called diamond reports and therefore are only issued for genuine diamonds. If your report is not referred to as a "diamond grading report" then there should be an argument attesting that it is genuine diamond.

    Weight. The complete carat should be given.

    Dimensions. Any diamond, from a shape, needs to be measured as well as the dimensions recorded as a method of identification, particularly for insurance/identification purposes. The scale given over a diamond report are incredibly prices and still provide information that is certainly important for several reasons. First, the scale will help you determine that the diamond being examined is, in reality, exactly the same diamond described in the report, since chance of having two diamonds with the identical carat and millimeter dimensions is remote. Second, in the event the diamond continues to be damaged and re-cut since the report was issued, the millimeter dimensions may provide a clue that something has been altered, that might modify the carat weight as well. Any discrepancy between your dimension that you simply or your jeweler manage measuring the stone, and the ones provided on the report, should be a warning sign to check the stone meticulously.

    Finally, the scale around the report also tell you if the stone is round or from round. Away from round diamonds promote for under people who tend to be perfectly round.

    Fine diamonds are "well-rounded".

    The diamond’s roundness will affect value, so it will be determined thoroughly from measurements from the stone’s diameter, gauged at several points around throughout the circumference. For a round diamond, the report will usually give two diameters, measured in millimeters and noted for the hundredth: for example, 6.51 as opposed to 6.5; or 6.07 as opposed to 6.0. These indicate the very best and lowest diameter. Diamonds are extremely rarely perfectly round, which explains why most diamond reports can have two measurements. recognizing the rarity of truly round diamonds, some deviation is permitted, as well as the stone will not be considered "out of round" unless it deviates by more than the established norm, approximately 0.10 millimeter inside a one carat stone. In a one carat diamond, if your difference is 0.10 or fewer, then a stone is known as "round." If the difference is bigger, it can be "out-of-round."

    To calculate an acceptable deviation with a particular stone, average the top along with the low diameter dimension given and multiply time by 0.0154. By way of example, in the event the dimensions given are 8.20x 8.31, the diameter average is 8.25 ( (8.20 + 8.31)/2). Multiply 8.25 by 0.0154 = 0.127. This is the acceptable deviation allowable with this stone (between 0.12 and 0.13). The particular deviation in this example will be 0.11 (8.31 – 8.20), within the tolerance, this diamond will be considered "round." Some flexibility is permitted on diamonds over two carats.

    Determined by degree of out-of-roundness (simply how much it deviates from being perfectly round), price might be affected. The higher the deviation, the lower the value needs to be.

    Dimensions for fancy shapes

    While dimension for fancy shapes diamonds usually are not as critical as these are for round diamonds, there are length to width ratios which can be considered "normal" and deviations may result in price reductions. The subsequent reflect acceptable ranges:

    Pear shape: 1.50:One to one.75:1

    Marquise shape: 1.75:One to two.25:1

    Emerald shape: 1.50:1 to 1.75:1

    Oval shape: 1.50:1-to-1.75:1

    To better understand what this implies, let’s look at a marquise diamond as an example. If it is report showed the gap to get 15 millimeters and the width to get 10 millimeters the space to width ratio could be 15 to 10 or 1.5:1. This may be acceptable. If, however, the size were 30 mm long by 10 mm wide, the ratio can be 30 to 10 or 3:1. This would be unacceptable; the ratio is simply too great, along with the result’s a stone that seems way too really miss its width. Note: A long marquise is not necessarily bad, and some people should you prefer a longer shape, yet it’s crucial that you recognize that such stones should cost under those that have normal lengths. Remember the space to width ratio of fancy cuts, and adjust the price of which aren’t from the acceptable range.

    Evaluating proportioning from your report

    As previously mentioned, good proportioning is as essential to diamond because it is towards the male or female who wears it! The proportioning, especially the depth percentage and table percentage, s what determines how brilliance and fire the stone will have.

    The information provided on diamond reports associated with proportions is critically important for round, brilliant cut diamonds. Unfortunately, it is merely of minimal use with fancy fancy shape diamonds. For fancies, you need to figure out how to rely on your eye to tell set up proportioning is appropriate: are available variations brilliance through the stone? Or flatness? Or liver spots such as "bow-ties" resulting from poor proportioning.

    Evaluating the proportioning of an diamond is as critical as evaluating the colour and clarity grades. Diamonds which are cut close to "ideal" proportions, stones with "excellent" makes can easily are more expensive compared to the norm while diamonds with poor makes sell for less; very badly proportioned stones should be priced for a smaller amount. The info with a diamond report will help you evaluate the proportioning and know regardless of whether you ought to be paying more, or less, for a particular diamond.

    Depth percentage and Table percentage critical for beauty

    To discover whether or not a round stone’s proportioning, so essential to its beauty, is great, consider the part of the claim that describes depth percentage and table percentage. The depth percentage represents the depth from the stone, the distance in the table to the culet, as a number of the width in the stone. The table percentage represents the width of the table like a number of the width in the entire stone. These numbers indicate how good a round stone has been decline in relation to its proportioning, and ought to adhere to very precise standards. The might be able to see variants sparkle and brilliance, but you may not be in a position to discern the subtleties of proportioning. The percentages around the report should fall in a fairly specific range for the stone to be judged acceptable, excellent, or poor.

    Some reports provide details about the crown angle. The crown angle notifys you the angle from which the crown portion may be cut. This angle will get a new depth and table percentage. Normally, when the crown angle is between 34 and 36 degrees, the table and depth is going to be excellent; between 32 and 34, good; between 30 and 32 degrees, fair; and much less than 30 degrees, poor. If the exact crown angle is given, it is probably considered acceptable. Otherwise, you will find there’s statement indicating that crown angle exceeds 36 degrees, or perhaps less than 30 degrees.

    Depth percentage

    A round diamond cut using a depth percentage between 58 and 64 percentage is usually a pleasant, lively stone. You ought to note, however, that girdle thickness will affect depth percentage. A top depth percentage could originate from a thick or very thick girdle, then when checking depth percentage about the diamond report, look into the girdle information too.

    Stones using a depth percentage over 64% or under 57% will usually be too deep or too shallow to indicate maximum beauty and should niche for less. In the event the depth percentage is too high, the stone will look smaller than how light it is indicates. When the depth percentage is exceptionally high, brilliance can be significantly affected. Diamonds which are so shallow, that is, stones with such low depth percentages, they have no brilliance and liveliness at all. When dirty, such stones look no superior to some glass.

    We avoid diamonds with depth percentages over 64% or under 57%. Should you be attracted to such diamonds understand that they should niche for a lot less per carat.

    Table Percentage

    Round diamonds cut with tables starting from 53% – 64% usually bring about beautiful, lively stones. Diamonds with smaller tables usually exhibit more fire than these with larger tables, but stones with larger tables could have more brilliance. As you see, table width affects the diamond’s personality, but deciding which personality is more desirable is a couple of personal taste.

    Finish

    Under finish around the diamond report, you will find an evaluation of the diamond’s polish and symmetry. Polish may serve as an indicator from the care taken by the cutter. The standard of the stone’s polish is really a component that can not be ignored in evaluating the entire quality of the diamond, with its cost and value. Polish can be described for the report as excellent, great, good, fair, or poor. The cost per carat must be less on diamonds with "fair" or "poor" polish. Cost per carat is normally more for diamonds which have "very good" or "excellent" Polish.

    Symmetry describes several factors:

    How the facet edges align collectively;

    get the job done facets in one side of the diamond match corresponding facets around the opposite side;

    whether or not facets inside the top part of the diamond are properly aligned with corresponding ones towards the bottom portion.

    If the symmetry is referred to as "fair", or worse, something no longer has enough line.

    When looking at symmetry, the most important location to check could be the alignment from the crown (top) to the pavilion (bottom). If it is not good, whenever they a visual alteration in the beauty of the stone, and correspondingly in their price. To test for proper alignment here, simply look at the diamond from your side to find out set up facets just above the girdle align using the facets just underneath the girdle.

    If the upper and lower facets don’t lineup, this implies sloppy cutting and, more vital, the general attractiveness of the diamond’s weakens. This can slow up the price over other symmetry faults.

    So how exactly does the girdle affect value?

    The girdle is yet another important item described on diamond grading reports. The report will indicate whether or not the girdle is polished, or faceted, and the way thick it can be. Girdle thickness ie very important for two main reasons:

    It affects value, and

    It affects the diamond durability.

    Girdle thickness varies from extremely thin to extremely thick. Diamonds with girdles that are excessively thin or thick normally cost less than other diamonds. An extremely thin girdle increases the probability of chipping. understand that despite their legendary hardness, diamonds are brittle, so thin edge poses a larger risk.

    If the diamond comes with a extremely thick girdle, your money ought to be reduced somewhat since the stone will look smaller compared to another diamond the exact same weight having a more normal girdle thickness. The reason being additional weight has been consumed from the thickness with the girdle itself.

    There are a few cases certainly where an very thick girdle is appropriate. Shapes which may have a number of points, for example the pear shape, heart, or marquise, might have thick to very thick girdles in section of the points but still be in the suitable range. Here the extra thickness in the girdle helps protect the points themselves from chipping.

    Generally, a diamond ring having an extremely thin girdle should promote for lower than one with an extremely thick girdle as a result of diamond’s increased vulnerability to chipping. However, in the event the girdle is really a lot too thick (like older diamonds), the cost can also be significantly less for the reason that stone cam look significantly small compared to other diamonds of comparable weight.

    The Culet

    The culet appears like a spot towards the bottom of the diamond, but it’s normally another facet, a small, flat polish surface. This facet should be small or very small. A smaller or really small culet won’t be noticeable from the top. Some diamonds, today, are pointed. This means that there really is no culet, that the stone has been cut straight down to a degree instead. The larger the culet, the greater visible it will likely be make up the top. The greater visible, the lower the expense of the diamond. Diamond described as having large or "open" culet as in old European or old-mine cut diamonds are less desirable, since the appearance from the culet results in a lowering of sparkle or brilliance on the very center of the stone. These stones normally must be re-cut, along with their price should take the need for re-cutting. for the similar reasons, a chipped or broken culet will seriously detract from the stone’s beauty and significantly lessen the cost.

    Color and Clarity

    Along with and clarity grades over a diamond report are the items everybody is acquainted with. These are key elements in terms of determining the price of a diamond ring, but because the preceding discussion has demonstrated, they don’t tell the whole story regarding the diamond.

    A word about fluorescence

    Fluorescence, if there are any, is likewise indicated on the diamond grading report. It’s going to be graded weak, moderate, strong, or very good. Some reports indicate the colour with the fluorescence as blue, yellow, white, and so forth. If fluorescence is moderate to very good as well as the color isn’t indicated, you should ask the jeweler to inform you what color the stone fluoresces. A stone with strong yellow fluorescence should sell for less as it can look more yellow laptop or computer is really when worn in daylight or fluorescent lighting. The presence of blue fluorescence will not detract, and in some cases might be considered an added bonus as it will make the stone appear whiter laptop or computer really is in daylight or fluorescent lighting. However, in the event the report show a very strong blue fluorescence, there can be an oily or milky appearance on the diamond. If your stone appears milky or oily for your requirements as you view it, specially in daylight or fluorescent light, it must cost less.

    Take note of the full clarity picture provided

    The location, number, type, and hue of internal and external flaws will probably be indicated with a diamond grading report, might include a plotting, d diagram showing all the details. Make sure you carefully note every detail beyond the cumulative grade. Remember, the position of imperfections may affect value.

    A trusted diamond grading report is not issued over a fracture-filled diamond, most labs is not going to issue a written report on diamonds that have been clarity enhanced with that method. Diamonds will be returned with a notation that it must be filled and can’t be graded. Reports are issued on diamonds which were clarity enhanced by laser. Remember, however, it does not matter what the clarity grade, a lasered diamond should not cost less than another with the same grade.

    Your final word about diamond reports

    Diamond grading reports provide a very useful tool to help in comparing diamonds and evaluating quality and price. But the key with their usefulness is proper idea of how to read them, and the way to look at the stone. Those who take time to learn and understand what they’re reading and, therefore, what they are really buying, will have a major advantage over people that do not.
