Forest green against dark metal. This coffin-cut moss agate couples ring set pairs a coffin-cut natural green moss agate on blackened silver for her with a black tungsten band for him — a bold, gothic his-and-hers pairing for couples drawn to nature with an edge.
Natural moss agate
Coffin cut
Gothic black
Three-piece set
Black tungsten + sterling silver
His & hers
Two rings, one dark forest
Her blackened coffin ring and his black tungsten band share the same green, tree-like stone — darker and edgier than our bright kite versions, designed to be worn together and striking apart. It's a standout in our collection of gothic couple rings and among our moss agate couples rings, made for gothic, forest, or non-traditional weddings, alternative engagements, promise rings, or a meaningful anniversary.

Her Rings
Solid 925 sterling silver in a black ruthenium finish — a rich, smoky blackened-silver — centered on a coffin-cut natural green moss agate with simulated-diamond accents, plus a slim 1.7 mm matching band.
His Ring
An 8 mm polished black tungsten carbide band with a silver stripe and a natural moss agate inlay — comfortable, everyday-ready, and boldly dark.
The moss agate
Her center is a coffin-cut natural green moss agate, prized for the mossy, tree-like inclusions suspended inside it, and because it forms in nature, no two are ever alike — yours will share the green forest character of our photos but carry its own pattern. Long loved as a symbol of harmony, grounding, and new beginnings, it makes a set that feels genuinely one-of-a-kind.

Metals & everyday wear
Her ring is solid 925 sterling silver with a black ruthenium finish for a deep, smoky blackened-silver look next to his black tungsten carbide, one of the hardest, most scratch-resistant metals in fine jewelry, with a comfort-fit interior. Both are hypoallergenic and nickel-free, and her ring is available unplated or as a solid gold custom upgrade.
