Collection: Gemstones

Our diamonds, gemstones, and precious metals are sourced in a responsible and sustainable manner. Gemstones are sourced directly from small independent mines, gemstone cutters, and dealers in gem regions around the world. Wherever possible, we utilize raw materials and alloys that have been recycled.
