Fancy Color Diamonds

The 4C color grade scale doesn't apply to fancy colored diamonds which come in hues of yellow, brown, red, pink, blue and green. Most colors are extremely rare and priced accordingly. Fancy color diamonds are given a color grade from least to most valued of "Fancy-Light", "Fancy", "Fancy-Intense" or "Fancy-Vivid" based on the level of saturation in their color. The largest fancy color diamond we've sold to date was a fancy-intense natural yellow diamond, certified by GIA to be flawless and weighed 6.54cts.

Learn Before You Buy

To understand how pricing a diamond works you must first learn the 4Cs (Color, Clarity, Cut and Carat) of a diamond. The 4Cs combine to give a diamond its value. We have put together a wonderful resource here for you to take advantage of. Learn about each of the 4Cs and how GIA (Gemological Institute of America) grades each one. Understanding the 4Cs and how diamonds are graded is the first step in making a smart purchase.

Once you feel comfortable with diamond grading or prefer to learn in person, give us a visit. We provide a free diamond education and cover tips on what to look for when shopping. You may also request to view your own specific diamond selection. We discuss and compare diamonds, looking at how each diamond's grade could effect the overall design of your new jewelry piece. As your direct diamond supplier, a good diamond education is always free.

Diamond Anatomy


A diamond's color can range on a letter scale from D-Z. The scale measures the lack of faint-yellow in a diamond with "D" being colorless and the highest grade. Diamonds used in jewelry are typically "J" or higher. We specialize in D-F colorless diamonds.

The clarity scale is used to measure imperfections in a diamond. A 10X magnification is used when grading for clarity. Imperfections disrupt and scatter the light in a diamond. The less imperfections the rarer the diamond and higher the grade. Flawless is very rare.

GIA Diamond Clarity
GIA Diamond Clarity Grades


The cut of a diamond dictates how much light is captured by the diamond and in turn how brilliant the stone is. Every diamond is rated from "Excellent" to "Poor". If cut to ideal proportions the stone will capture more light giving the diamond an "Excellent" cut.

Carat Weight

A carat is equal to 200 milligrams. Engagement ring centers are typically .75ct to 2ct with extravagant rings containing 2ct to 6ct diamonds. The diamond size chart may vary based on your monitor and should be used for a size comparison reference only.
