Our Jewelry Ethos


Everyday Fine

Fine jewelry shouldn’t be reserved for special occasions like the fine china that only comes out at holidays. We encourage our clients to invest in unique, high-end but wearable pieces that will last a lifetime.

Love Your Bones

We treasure the “old bones” of a one-of-a-kind heirloom piece and the meaning that comes along with it. Nothing excites us more than thoughtfully working with our client to reimagine something so special.

Sparkle With Substance

We foster a culture that values careful collecting over having just to have. Our uniquely sourced stones and distinct shapes are intended to bring people together and help them create something that’s theirs.
