🔨 STRUCTURE * I Know * CLEAN LINES AND ANGLES – Inventive – Powerful – Bold – Connective
The Black Star Diopside Ring Size 7 Argentium Silver Buttonhole design blends clarity and strength. A 4.5 carat Black Star Diopside sits within a loop of silver that circles the gem and flows back into the band. When light moves across the surface, a fine star appears and shifts gently, giving quiet contrast to the clean silver form.
Design & feel
I shape each Buttonhole ring in Argentium 940 silver to emphasize balance and structure. The curved band supports the gemstone while staying smooth against the skin. Because the surface holds both bright polish and soft texture, it feels bold yet understated.
About the stone
This 4.5 carat Black Star Diopside shows a dark forest tone crossed by a glowing four-point star. As you move your hand, the light glides across the gem, revealing flashes of depth and shadow. The star’s movement adds a subtle rhythm to the strong, simple lines of the ring.

Materials & care
I craft each ring in Argentium 940 silver — bright, tarnish-resistant, and nickel-free — with a satin finish that highlights its shape. After wearing, simply wipe it with a soft, dry cloth. Avoid dips or harsh polishes to keep the surface luminous. Learn more:

Each Buttonhole ring is hand-formed, fused, and hammer-finished for strength. I then heat-treat the Argentium to activate its germanium layer for lasting brightness. Finally, I set the Black Star Diopside by hand and polish it to reveal the shifting light within the stone.
