At Karat, you can choose with confidence. We pre-select, so only the finest quality diamonds are available to you.

Before you shop, you can relax knowing we have eliminated the less desirable grades, leaving only the finest grades from which to pick. So choose with confidence.

Consistent with our exceptional diamonds, our color diamonds and fine jewelry also meet a higher standard. But that doesn’t mean a high price. Our efficient business model assures you the best jewelry for the price.

Diamond Jewelry

Karat diamonds are limited to the strictest standards of cut, clarity and color. Each of our white diamonds are colorless to near colorless (range D-I) with remarkable clarity (range FL – SI).

Color Diamond Jewelry

As always, Karat gives you more choice. For the discerning taste we offer the Karat color diamond collection of the rarest selections of color diamonds available in the world.

Exclusively at Karat - rarer than white or even color diamonds, explore the Karat Cross Diamond collection. This discovery is not manufactured by man (and never will be). Each cross diamond is truly a miracle, derived the same way as white or color diamonds, but far rarer. Choose wisely, no two are alike.

Platinum Jewelry

Our platinum jewelry uses only jewelry grade platinum for strength and durability. Each loose diamond engagement setting also features platinum prongs for security and strength.

Gold Jewelry

We specialize in 18 karat gold for its beauty and strength (pure 24 karat gold is too soft for jewelry applications). Occasionally, you will find 14 karat gold in certain components of our jewelry, such as hinges, clasps and earring posts, where the added strength is required for durability.

Silver Jewelry

Our sterling silver jewelry is both beautiful and durable. The purity is stamped on each piece to assure its quality.
