Unfortunately, there are sales people who are willing to take advantage of inexperienced diamond buyers. We sadly see people with diamonds who have been "taken" at other jewelers and have paid far more for an inferior diamond. Sometimes these sales people know, and sometimes they don't really know what they're selling and are just trying to make the best sale.
When you make your appointment at Washington Diamond, you are promised undivided attention from a knowledgeable and trustworthy diamond expert - not just a sales person. We guarantee that you'll feel confident about your purchase. You can rest assured that you are in fact getting what you're paying for while still receiving a great value.
The standard color-grading scale from the Gemological Institute of America (GIA) assigns alphabetical letters to indicate color quality; these qualities range from colorless to increasing tints of yellow that you can see unaided. Color is the most important factor to a diamond’s value.
The color-grading scale developed by GIA is the most widely accepted in the world. The letter "D" is the purest value, representing a total lack of color, or a "colorless" stone. As you move down the scale (and the alphabet) through to near-colorless, or “Z” (a faint yellow or brown), you will see an increase in the tint of yellow, visible with the unaided eye.
As a diamond's tint increases, its value decreases. Diamonds beyond "Z" that have color are classified as "fancy," or "fashion" jewelry. These are the blues, pinks, reds, etc. A diamond can't be color graded face-up because the brilliancy (the return of light to the eye by the facets) and the dispersion (spectral colors) confuse the eye.
Therefore, color grading is done face-down on a white card or tray. For proper illumination, a color-corrected fluorescent light, free of ultraviolet rays should be used. This light is roughly equivalent to North daylight. Diamonds that are colorless to near-colorless are the best to use in jewelry (Colors D-J).
If you are looking for a rarer diamond, get a diamond that is colorless (D-F). If you prefer to get a larger diamond for the same budget, get a near-colorless stone (G-J).
Diamond grading reports are issued by independent gemological laboratories. While there are several grading laboratories, Washington Diamond sells diamonds that are graded only by the Gemological Institute of America (GIA - GIA.edu).
It is our opinion that GIA has the most accurate and valuable standards that ensure proper quality in a diamond. A grading report recognizes quality characteristics identified in a uniform laboratory environment, which allows you to gauge and compare quality and value.
