The color grading begins at D and continues down the alphabet to Z. Truly colorless stones are very expensive. Colors through D,E,F,G,H,I, and J are considered white. Colors K,L,M,N,O,---- to Z have either a brown or a yellow tint to them. These yellow and brown stones are very inexpensive and are not very appealing to the eye.
