With Valentine’s Day just a few weeks away, we’ve started to see romance on the minds of many of our customers. For some, the holiday is bringing them in for earrings, pendants or other colored gemstone pieces. But for others this can also be the time to make that most important purchase – the diamond engagement ring.
An interesting irony, a diamond’s “color grade” means, in actuality, its lack of color. A structurally perfect and chemically pure diamond has no hue, like pure water, and this lack of color gives it a higher value. A totally colorless diamond allows light to pass through it easily, resulting in a rainbow spectrum of light dispersed from the stone.
The rating of a diamond’s color does not pertain to the face of the diamond, but is a grade for the body color of the stone. Assessing color is best done by looking at the diamond on its side, against a white background, underneath a daylight fluorescent bulb. The appearance of the stone can be influenced by different types of light and reflections from other elements, and these controls can ensure you have the best vantage point.
We use the GIA’s D-to-Z color-grading system, which measures the degree of a diamond’s color purity by comparing a stone under set lighting and specific viewing conditions to stones of established color value. Stones of D/E/F color grade are colorless, while T/W/Z have the most yellow in them.
While there’s a variety of color-grading systems can be applied to colorless diamonds, diamonds actually come in a variety of actual colors as well (i.e. blue, red and pink). While all diamonds have the same mineral composition, it’s the stone’s chemical composition that influences its color.
