For designers, collectors, and anyone building a custom piece, a loose gemstone is where it begins. Our loose collection spans diamonds, emeralds, rubies, sapphires, and more, each sold on its own and ready to set.

Choose by stone, cut, size, and origin, natural or lab-grown. Whether you are replacing a stone, planning a custom design, or collecting, every gem is measured and described so you know exactly what you are buying.

Frequently Asked Questions

Can I buy a loose gemstone without a setting?

Yes. Every stone in this collection is sold loose, on its own, so you can set it in a design of your choosing or add it to a collection.

Are your loose gemstones natural or lab-grown?

We offer both. Natural stones are earth-mined and one of a kind; lab-grown stones share the same properties at a gentler price. Each listing states which it is.

How are loose gemstones measured?

Loose stones are described by millimeter dimensions and, for diamonds, by carat weight, along with shape and quality, so you can match a stone to a setting.

Can I use a loose gemstone for a custom piece?

Absolutely. Loose stones are ideal for custom rings, pendants, and repairs. Choose your stone, then have it set by your jeweler.
