Lab Grown Fine Jewelry Necklace

From a single stone on a fine chain to a full line of sparkle, a lab grown diamond necklace frames the face in a way few pieces can. Everything in this collection is set with lab grown diamonds and handcrafted in sterling silver or 10K, 14K or 18K gold.

Lab Grown Diamond Pendant or Tennis Necklace?

A lab grown diamond pendant is the everyday choice: light, easy to layer and simple to wear with any neckline. Solitaire pendants feel timeless, while heart and halo designs add a personal touch; browse our pendant collection or the lab diamond heart styles. A lab grown diamond tennis necklace is more of a statement piece, best for special occasions and open necklines.

Chain length changes the effect. Around 16 inches sits near the collarbone, 18 inches is the most common length for pendants, and 20 inches or longer works over higher necklines. Planning a gift? Our fine jewelry gift ideas can help you choose.

Every necklace is handcrafted to order, ships free worldwide and comes with 30-day returns.
