Meet your new everyday sparkle—our limited-edition Herkimer Diamond collection is here and won’t last long. These naturally double-terminated quartz crystals are known as “Herkimer Diamonds” for their exceptional clarity and brilliance, formed over 500 million years ago in the rock beds of Herkimer County, New York. Each stone is raw, radiant, and completely unique—just like you.
Strung on our signature handspun rope, these necklaces, bracelets and earrings are waterproof, kid-proof, and life-proof—made for real life and every wild, beautiful moment that comes with it. This is everyday jewelry that’s up for any adventure.
Choose from exclusive styles designed to showcase the beauty of these high-vibration crystals. Whether you’re stacking it with your Tula favorites or letting it shine solo, this piece brings a touch of grounded elegance and energetic clarity wherever you go.
Why it stays on
The rope is metal-free, so there is nothing to tarnish, wear through or itch. Real freshwater pearls and natural stones on hand-spun nautical-grade rope, soft enough to sleep in, made to your length in Texas. Ocean, pool, shower and sweat are all fine. Skip long soaks in a hot tub with the pearls.
The rope carries a lifetime warranty. If it ever fails, we restring your pearls. They're still yours, and they still carry your history.

The rope is the whole thing.
Most jewelry comes off before the pool, the shower, the gym. Ours does not.
Every piece in your stack is built on nautical-grade rope, hand-spun in Texas. Waterproof. No metal chains to tarnish. Lightweight.
Swim in it, sweat in it, sleep in it. It still looks new.
