A one-of-a-kind ring featuring a rutilated quartz masterfully cut using the free-flowing, expressive hand-polishing technique of gem cutter Canna Oshiro. This piece showcases Oshiro's unique sensibility, with bold facets carved to evoke the crystalline essence of the quartz, while copper-brown rutile needles nestle against layers of inclusions that resemble geological strata.

The bespoke setting delicately cradles the gem’s multidimensional form, enhancing its intricate beauty from every angle. The ring shank, etched with textures reminiscent of soft fur, creates an organic rhythm that harmonizes seamlessly with the gemstone. Together, they form a cohesive, nature-inspired design that graces the hand with elegance and brilliance.

This ring is a singular work of art, exuding an undeniable presence as though a treasure has been brought to life on your finger.

"Canna Oshiro × Ryui"

This is the first collaboration with gem cutter Canna Oshiro, renowned for her mastery of the rare hand-polishing technique. Ryui entrusted meticulously selected raw gemstones to Oshiro, whose signature hand-cutting transforms them into one-of-a-kind jewels. The resulting pieces are truly singular, born from a deep dialogue with each unique stone.

Each gem is polished with Oshiro’s impeccable craftsmanship and artistic intuition, resulting in free-spirited and captivating forms. The irregular yet striking facets, a hallmark of hand-polished stones, are paired with Ryui’s gracefully designed settings. This synergy of artisanal techniques and bold creativity gives life to extraordinary jewelry, where each piece tells its own story.

Selecting your ring size

We recommend choosing a size that you can comfortably wear without feeling pressure or tightness when you make a fist, and without discomfort between adjacent fingers.

For wide rings of 6.0 mm or more
Compared to the number measured with a typical ring gauge, a wide width ring may feel a little tight to wear due to its large surface area. When considering a wide ring, we recommend that you choose a slightly looser size than you usually wear, 1 to 1.5 sizes up.

Please note that some rings cannot be resized due to their design.
Please check the details on each product page.
