Geometry that grew itself.

A crystal is matter that arranged itself: its atoms lock into a repeating three-dimensional lattice, and with room to grow, that order shows as flat faces meeting at exact angles. Many pieces also record their history — phantoms, twinning and inclusions trapped as they grew. Our collection runs from amethyst and dioptase to malachite, prehnite and tree agate, and no two specimens are alike. Browse below, then visit our Westminster, CA showroom to see them in person.
