We buy diamonds of all shapes and sizes, instantly in our store. Weather your diamond is loose or set in new, old, broken, vintage, or antique settings, we’ll still buy it! Evaluating a diamond takes much more skill and attention to detail which is why not very many companies can do it properly. At Crown Gold Exchange, we meticulously train our professionals to know what to look for to give the most accurate evaluation of your diamond. Most of our professionals are diamond certified through GIA so you know you are getting a professional, objective evaluation of your stone. There are 4 main items to look for when identifying the characteristics of a diamond that will affect the overall price. Those are the cut, color, clarity and carat weight.
The diamond cut has to do with the shape and positioning of a diamond’s facets. Depending on the angles and the way that it’s cut will give the diamond life, brilliance, dispersion and scintillation. The shape can be a round, princess, pear, oval, heart, emerald, cushion, marquise, asscher, miner, radiant, or trillian. A round diamond cut is the most traditional but carries the highest value because it has the most “loss” when the diamond is originally cut.
Clarity has to do with what you see inside the diamond when you take a 10x magnification to the top of the diamond. The less inclusions, the better the diamond is in quality. Some inclusions you might see are pinpoints, feathers, clouds, and carbon deposits. The GIA Diamond Clarity Scale has 6 categories, some of which are divided, for a total of 11 specific grades.
No inclusions and no blemishes visible under 10x magnification
Internally Flawless (IF) No inclusions visible under 10x magnification
Very, Very Slightly Included (VVS1 and VVS2) Inclusions so slight they are difficult for a skilled grader to see under 10x magnification
Very Slightly Included (VS1 and VS2) Inclusions are observed with effort under 10x magnification, but can be characterized as minor
Slightly Included (SI1 and SI2) Inclusions are noticeable under 10x magnification
Included (I1, I2, and I3)
Inclusions are obvious under 10x magnification which may affect transparency and brilliance
Many inclusions and blemishes are too tiny to be seen by anyone other than a trained diamond grader. To the naked eye, a VS1 and an SI2 diamond may look exactly the same, but these diamonds are quite different in terms of overall quality. This is why expert and accurate assessment of diamond clarity is extremely important.
In diamond terms, the less color a diamond has, the better and more valuable. Most diamonds have a yellow or brown natural tint to it which is described as the color. Even though it might not look like a color at all, the very slightest tint will affect the value. Diamond colors start at D (colorless) and go all the way to Z (light). They are set in categories from colorless (D, E, F), near colorless(G, H, I, J), faint (K, L, M), very light (N, O, P, Q, R), and light (S,T,U,V,W,X,Y,Z).
Diamond Carat Weight
Diamond carat weight is measured as how much a diamond weighs. Carat weight is measured to the hundredth of a decimal point. There is a significant difference in value when it comes to a diamond being 0.99 carats and 1.00 carats so accurately measuring the weight of the stone is very important. A single stone is exponentially more valuable than many smaller stones with the same weight. 100 diamonds each being 0.01 carats equals a total of 1.00 carat but a single 1.00 carat stone could be worth 10-100 times the value of the smaller stones.
