Gemstone Customs- Made to Order
Every stone in this collection was selected individually, over years, before a single piece of metal was carved.
What you're looking at is a decade of collector inventory — Afghan tourmalines from pegmatites in Kunar and Nuristan, color-zoned by iron and manganese ratios that shifted during crystallization and will never shift that way again. Unheated Montana sapphires from the Missouri River watershed, one of the only commercially mined precious gemstones native to the United States. Spinel whose lavender and cornflower blue come from chromium and iron substituting into a cubic magnesium aluminum oxide lattice that has no cleavage planes and no treatment history. Lightning Ridge crystal opals whose play-of-color is diffraction physics — silica spheres in a repeating grid, not pigment, not coating. More to come.
None of these stones are commercial inventory. Each one is the specific stone in the photograph. When it sells, this listing closes.
Each piece is made to order in your chosen metal, setting, and size — hand-carved in wax, cast, set, and finished by me. No CAD, no molds, no production runs. The mark of the hand is not incidental. It is the point.
Treatment is disclosed on every piece, completely, because you are buying something that will outlast you and you deserve to know what it is at the atomic level. Unheated status is noted where it applies. Heat treatment, where present, is explained — not hidden.
Select your stone. I've provided recommended setting(s) that will fit the stone geometry beautifully. If you want the stone or similar for a full custom design please reach out by email to start the custom process as described in the FAQ.
