100 East Fine Jewelry’s diamonds are meticulously hand selected to assure we use only those of exceptional color and clarity. We ‘sweat the details’ when it comes to assuring our colorless scale diamonds meet all aspects of the GIA standardized 4C’s grading scale. We use only natural, untreated diamonds graded as colorless or near-colorless (D–J GIA color grades) with clarity grades in the GIA VVS1-SI2 range. Beyond color and clarity, we carefully evaluate the cut to make sure our diamonds possess extraordinary sparkle and fire.

Except for the black diamonds we use, our fancy colored diamonds are untreated natural diamonds selected for their vibrancy of color and overall appearance. We select only those colored diamonds which display exceptional beauty. Our black diamonds are natural, but are treated to create the unique black color. Because of the treatment it’s common for black diamonds to reveal minor surface imperfections without magnification.

The vast majority of our jewelry pieces contain diamonds, regardless of brand. Our 100 East Fine Jewelry brand uses diamonds extensively. The Sas E Gems and Gordon’s Curated Selections brands typically use fewer numbers of diamonds and in a few instances may use no diamonds at all. Despite the fact that diamonds are the hardest material on earth, 58 times harder than anything else in nature, care should be taken in handling diamond jewelry.
