Lab Grown Diamond Promise Rings

A promise ring marks a commitment without the formality of an engagement. This collection brings together our lab grown diamond promise rings, from simple solitaires to floral clusters, open wraps, bypass designs and toi et moi pairings. Lab grown diamonds share the same chemical makeup and sparkle as mined diamonds, and every ring is made to order with free worldwide shipping.

Choosing a Promise Ring Style

For a clean, classic look, choose a round, oval, princess or radiant solitaire. If you prefer something softer, the floral, leaf and nature-inspired designs wrap the finger with small lab diamonds. Heart and knot motifs carry a clear symbolic meaning, while half eternity bands sit low and suit everyday wear. To see more band options, browse our lab diamond eternity rings or lab grown diamond wedding bands, which also stack well with a promise ring.

Metal Options and Sizing

Each ring is available in 925 sterling silver or in 10K, 14K and 18K gold, in white, yellow or rose. Silver keeps the price accessible, while gold is a durable choice for daily wear. Because every piece is made to order, getting the right size matters. Use our ring size guide before you order.
