Brand: Ryui
Price: 325000.0 JPY
Availability: InStock

A one-of-a-kind Starburst Gold Rutilated Quartz ring featuring hand-polished cutting by gem polisher Canna Oshiro. Within the highly transparent quartz, fine rutiles extend like streaks of light, densely spreading and giving rise to a delicate sparkle. The stone is intentionally cut to leave the natural rough texture on the back, creating undulations reminiscent of a coral reef beneath the sea within the fresh quartz. The thin beams of rutile rising through the stone harmonize with these natural formations, producing a unique scene where organic irregularity and refinement coexist. The platinum frame cradles the stone like a painting, transforming it into a ring that adds a serene calmness to the fingertip. As if wearing the breath of nature itself, this one-of-a-kind ring evokes a deep, lingering impression with every glance.

" Canna Oshiro × Ryui "

A collaboration series with gem cutter Canna Oshiro, a rare practitioner of traditional hand-cutting techniques. Entrusting her with rough stones carefully selected by Ryui, she creates truly one-of-a-kind jewels through her distinctive hand-cutting approach. The loose stones, polished with Oshiro's unique aesthetic sense and precise craftsmanship—drawn from the inspiration she gains through an earnest dialogue with each expressive rough stone—are all imbued with a free and generous allure. These special pieces of jewelry are born from enveloping the irregular yet beautifully faceted, hand-polished stones in open, flowing designs, resulting in creations where artisanal skills unite in perfect harmony.

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.
