Antique Diamonds
When we debuted our collections in 2014, many of our rings were set with antique diamonds, which Erika considers time capsules of a bygone era:
Each antique and vintage diamond marks a particular time in diamond cutting history, and with true antiques, especially those without recorded provenance, you can look at the diamond’s unique facet pattern, proportions, and characteristics to determine when it was cut. You’re holding a precise moment in time in your hand, and so we want our rings to capture that moment in a future heirloom. From old mine cuts and old European cuts, to the first mid-century modern round brilliants, these diamonds are all one of a kind and so special to us. – Erika Winters
Natural unheated Montana sapphires
Montana Sapphires
Montana sapphires are a treasured gemstone for us. Erika appreciates that these unique gemstones are mined and polished in the United States:
Our work is handcrafted in Seattle, Washington, where we are based. The U.S. origin of Montana sapphires is especially meaningful and reflects our sustainable business practices. Sustainability goes beyond where we source our gemstones. It’s also about supporting local craftspeople, gem miners, and stone suppliers in the U.S. – Erika Winters
All of our antique diamonds, natural modern diamonds, and colored gemstones are responsibly sourced. Contact us to learn more about our natural gemstones.

Labgrown Diamonds
We offer a selection of the highest quality labgrown diamonds. Labgrown diamonds are chemically and optically equivalent to natural diamonds and are not to be confused with simulants. The diamonds are grown using high-pressure, high-temperature or chemical-vapor-deposition processes that recreate the natural conditions that form diamonds under the earth’s surface. Contact us to learn more about our GIA and IGI graded lab-grown diamonds.
Colored Gemstones
We offer many distinctive colored gemstones, including sapphires, emeralds, rubies, garnets, and tourmalines, all hand selected by Erika, who is a GIA graduate gemologist. Contact us to learn more about our colored gemstones.
