Buying Diamonds and Determining Diamond Gemstone Value Diamond Color Diamonds are typically known to be colorless or 'white', but the most common colors are yellow and brown. The official color grading system for colorless to low-saturation yellow and brown diamonds ranges in scale from 'D' (completely colorless) to 'Z' (light-yellow). Fancy colors are graded on an entirely different scale. Diamond Clarity and Luster Diamonds exhibit a strong sub-metallic adamantine luster. Though diamonds can be transparent to opaque, only transparent stones are faceted. Diamond clarity is graded on a scale that factors both size and visibility of flaws and inclusions, ranging from 'FL' (Flawless) to 'I3' (large inclusions visible to the naked eye). Diamond Cuts and Shapes The most prevalent cut for diamonds today is the 'brilliant cut', followed by the 'passion cut' . The most popular diamond shape today is round. Other fancier shapes include pear, oval, radiant, princess (square), emerald (octagon), asscher, cushion, heart and trillion (triangular) shapes. Diamond Treatments Champagne, cognac and colorless 'white' diamonds are typically untreated. However, they may be artificially enhanced. Laser drilling can be used to remove inclusions.
