The most durable choice

Platinum is naturally white, so it never needs plating, and it is dense and hypoallergenic, making it ideal for sensitive skin. When platinum is scratched, the metal moves rather than wearing away, so prongs and settings hold diamonds securely for decades.

Is platinum worth it?

Platinum costs more than gold because it is rarer and heavier, but many couples see it as a one-time investment for a ring worn every day. Over time it develops a soft satin patina, which can be polished back to a high shine whenever you like.

Why platinum?

Platinum is a naturally white, dense and hypoallergenic metal that will not fade, making it the most durable choice for everyday wear.

How to choose

Start with the look you love, then pick the metal that matches your style and the diamond size that fits your budget. Prices in this collection range from $668 to $5,649, with shapes including round, oval, emerald, marquise, radiant and pear.

Are lab grown diamonds real?

Yes. Lab grown diamonds are made of pure carbon with the same crystal structure, hardness and sparkle as mined diamonds, and they are graded on the same color, clarity and carat scales. They typically cost 70 to 90 percent less and have a traceable, conflict-free origin.

Sizing, care and custom requests

Every piece is made to order, so you can choose your ring size, metal and, on many designs, the diamond size and quality. Clean your jewelry with warm water, mild soap and a soft brush, and store it separately to avoid scratches. Want a change to a design? Contact our team for a custom quote.
