Platinum Lab Grown Diamond Rings

They look nearly identical when new, so the decision is about wear. Platinum is denser, holds prongs more securely, patinas to a soft finish instead of wearing away, and is hypoallergenic. White gold is lighter and less expensive, but it is rhodium-plated and the plating warms in color over time. We recommend platinum for a ring worn every day.

Platinum does not wear away, it displaces. Daily contact pushes the metal around rather than removing it, so the surface develops a soft matte sheen called patina instead of thinning. Some owners prefer it; a workshop polish restores the bright finish whenever you want it. Gold, by contrast, loses a little material each time it is polished.

Density, mostly. Platinum is significantly heavier than gold, so the same ring takes noticeably more metal, and it is worked at higher temperatures. You are also buying a metal that needs no plating for the life of the piece. We carry 458 platinum designs across every shape we cut.

Platinum. It is hypoallergenic and contains no nickel, which is the metal most often responsible for a reaction. If you prefer gold, higher purity means less alloy, so 18k is generally better tolerated than 10k. We stock 458 platinum pieces across the range, every shape we cut.

Platinum carries the highest material cost by weight, because it is denser and more of it goes into the same ring. Between the three golds, purity moves the price more than color does — an 18k band costs more than a 14k band in the same color. Silver is the entry point at $179.
