How to choose lab grown diamond jewelry

About this collection
ABOUT THIS COLLECTION

Lab-Grown Diamond Necklaces, Pendants and Tennis Chains

A lab-grown diamond is a real diamond, grown instead of mined, with the same hardness and fire, and it is graded for color, clarity and cut the same way. Nearly every listing gives the karat, the carat weight and the grams. For a tennis chain, the stone size sets the width and the weight: how to choose a diamond tennis chain. To weigh one against a natural stone, read lab-grown diamond or natural diamond.

Every lab-grown piece, rings and earrings included, is on lab-grown diamond jewelry. Natural and lab-grown tennis chains share tennis chains, and men's diamond pendants have their own page at men's diamond pendants. Call or text 212-872-9692, or visit the showroom on 47th Street.
