Colored Gem Guide

Front Jewelers hand selects every single gem we sell to ensure that each one possesses the beauty and characteristics of a stone we would personally wish to own ourselves. When shopping for a colored gemstone, unless otherwise stated, it should be assumed that the gems you see are enhanced by trade-accepted practices such as heating and irradiation.

More information about Front Jewelers' Colored Gems is included below.

           Black Diamonds - We purchase our black diamonds from suppliers all over the world. All of the black diamonds we sell are color enhanced. Some also have a special coating polished on top. The enhancements are done to create an opaque black color that is even throughout the stone. The treatment / enhancements are permanent and covered under our Lifetime Warranty. All of our black diamonds are sourced ethically through diamond dealers in the US, Israel, and India substantiated GJEPC suppliers. They are responsibly documented and exported by our suppliers and the country of origin's government. 

Blue Diamonds - Our blue diamonds have been enhanced in color and sometimes clarity. The enhancement creates a sparkling, ocean blue. The treatment is permanent and covered under our Lifetime Warranty.

Brown Diamonds - Our brown diamonds are not color or clarity enhanced. Their beautiful, warm brown hue is naturally occurring.

Canary/Yellow Diamonds - Our yellow diamonds have been enhanced in color and sometimes clarity. The enhancement is made to create a dazzling and vibrant yellow hue. The treatment is permanent and covered under our Lifetime Warranty.

Colored Sapphires - Our blue, pink and yellow sapphires have been enhanced with heat to bring out their true potential. This completely natural process is typically done at the mine site using fire and sand. The treatment is permanent and covered under our Lifetime Warranty.

Colorless Sapphires - Our colorless/white sapphires are not enhanced. Their colorless and clear state is naturally occurring.
