Oxidized Cobalt Chrome Diamond Stacking Ring - "Pebble"

Rough like blackened bark, the oxidized cobalt chrome band of "Pebble" offsets the brilliance of a pure white diamond at its center, like a full moon against the rough darkness of night. Designer Sarah Graham draws this ring's texture from stones smoothed along a riverbed, pairing that dark, sculptural surface with the warmth of 18K yellow gold and a 0.20 ct diamond.

The textured band gives the diamond real contrast, while the organic surface keeps the ring feeling sculptural rather than traditional, a contemporary alternative to a classic polished band. Oxidized cobalt chrome is valued for its deep matte-black finish and durability, and here it does real work setting off the gold and diamond against something rougher.

This is a strong choice for someone who wants their diamond paired with genuinely irregular beauty. Worn alone as a quietly unconventional statement, or added to a stack for varied color and texture, currently a size 6.5.

FAQ

Will the color I see on my screen match the ring in person?
Diamond brilliance and the contrast between blackened cobalt chrome and yellow gold can read a bit differently depending on the light around them, and your monitor adds its own variation on top of that. Screen settings, video cards, and browsers can all affect color slightly, so the ring you receive may look a bit different than what you see here. By purchasing, you're acknowledging that possibility. If you'd like a true look before buying, we're happy to walk you through it over video chat.

Can this ring be worn by itself?
Absolutely. Its texture, mixed metals, and central diamond give it enough presence to stand alone, though it also plays nicely with a ring stack.

Is cobalt chrome the same as oxidized silver?
No. This design combines blackened cobalt chrome with 18K yellow gold. The dark contrast is integral to Sarah Graham's signature material-driven aesthetic.

How should I care for the ring?
Use a soft, dry cloth for routine care. Avoid abrasive cleaners and harsh chemicals, which may affect the finish. We can provide care guidance suited to this specific ring.
