We also strive to ensure that in none of the listings will you find treated or unnatural diamonds, they aren't part of our passion and there is no fun in listing them, however we can not guarantee that we've excluded them all, please ensure that when you review a diamond that it is exactly what you are looking for.
A diamond cutter cuts a diamond wrong and you might as well just chuck the diamond in the garbage. The responsibility is immense, read why. Diamond cuts
Technically, this is a measurement of the nitrogen levels inside the diamond. Realistically it is a measurement of color. Read more about how diamond color influences the cost of a diamond.
A diamond may be blessed with great color and a brilliant cut, but what can completely ruin the beauty of a diamond is the presence of inclusions and other internal characteristics. Diamond clarity is the measurement of the diamond's characteristics.
This is a unit of measurement, adopted in the early 1900's and most commonly used to describe the mass of a gemstone. A single CARAT represent 200mg (0.2 grams), or 0.007055oz, and is quoted to 1 / 100th of a gram, allowing a diamond to be .78 of a carat, for example. If between two identically graded diamonds, one is twice as large, it will be worth much more than twice the value. Carat changes the value of a diamond exponentially.
A diamond's brilliance is based on a number of factors, much of which has to do with geometry. There may only be a finite number of ways to cut a particular diamond that will yield the best possible example, and the path selected by the diamond cutter determines its measurements which influences how attractive the diamond is when cutting is completed and its ultimate value. The table, facets, girdle and other features can all be measured and presented in a diamond grading report, making it easier to source a diamond of a desired size, beyond carat.
Diamond cutters must determine where to place the facets of the diamond to yield the best diamond brilliance possible. A perfectly symmetrical diamond will have equal proportions in each facet. It is possible to look at a diamond through a loupe to see the symmetry of the facets.
Another reference found in a certificate, this is the space between the crowne and the pavilion (top and bottom). The thickness of the girdle can improve or damage the value of the diamond as it can directly impact the brightness of the stone.
Often found on a diamond grading report, a diamond cutter might take the time to facet the culet, which is at the end of the point of a diamond. Taking the time to do this can often strengthen the tip, helping it from being damaged.
After a diamond is cut, it is polished, and this can be graded. Simply put, the better the polishing job, the more it will contribute to the overall appeal of the finished product.
The measurement of how a diamond reacts to radiation of ultraviolet light, the less of a reaction, or fluorescence, the better, which is indicated by the color, ranging from none to blue or yellow, faint to strong.
