Round Cut Jewelry

Round cut jewelry is the largest collection we make, and for good reason: the round brilliant is engineered to return the most light of any shape. Here you will find rings, wedding bands, earrings, pendants, necklaces and bracelets in lab grown diamond and moissanite, all in sterling silver or 10K, 14K or 18K gold.

Lab Diamond or Moissanite: Choosing Your Round

Both stones look spectacular in a round cut, but they behave differently. Lab grown diamond is real diamond, identical in properties to mined stones and rated 10 on the Mohs scale, with a crisp white sparkle. Moissanite is lab-created silicon carbide at about 9.25 Mohs and shows more colorful fire, especially in larger sizes and bright light.

Size depends on the piece. For studs, 4 to 5 mm is subtle enough for the office, while 6 to 7 mm is noticeable across a room. For rings, a four-prong lab diamond solitaire shows the stone fully, and a six-prong head feels rounder. Our diamond size chart shows common sizes to scale, and you can find round studs among our moissanite earrings.
