Moss Agate & Emerald Celtic Knot Ring in 14K Solid Yellow Gold

This moss agate celtic knot ring centers a marquise-cut natural green moss agate — translucent with fern-like green “moss” inclusions, no two alike — framed by marquise lab-grown emerald accents along a twisted vine band worked with Celtic knot detail, all in warm solid yellow gold. A folk-romantic, woodland engagement ring where forest-green stones meet the endless-knot symbolism of eternal bonds.

The moss agate

The marquise center is a genuine natural moss agate — a translucent chalcedony quartz (about 6.5–7 Mohs) with green dendritic inclusions that look like moss or ferns suspended inside the stone. The “moss” is natural mineral patterning, so every stone is unique and yours will vary from the photos. Warm yellow gold amplifies the green character beautifully. Our moss agate meaning guide goes deeper on its patterns and lore.

The Celtic knot vine band & emerald leaves

The band's shoulders are sculpted into a twisted vine with interlocking Celtic knot detail — knots without beginning or end, a centuries-old symbol of eternity and an unbroken bond. Six marquise lab-grown emeralds flank the center like leaf clusters growing along the vine. Lab-grown emerald is real emerald (beryl), same chemistry and hardness (7.5–8 Mohs) as mined, clearly disclosed. Explore more moss agate engagement rings and our Celtic engagement rings. Our emerald buying guide covers lab-grown versus mined.

Why solid yellow gold

This ring is solid yellow gold — the metal itself, not plating or vermeil over a base metal. The warm tone flatters the moss-and-emerald green palette and suits the ancestral, Celtic feel of the design. The color is permanent: it won't wear off and won't turn your skin green. Choose your karat below; white or rose gold is available on request.

Sizing & care

Moss agate is about 6.5–7 Mohs and emerald 7.5–8 — both fine for daily wear with sensible care. Clean with warm soapy water and a soft brush, and avoid ultrasonic and steam cleaners, which emerald doesn't love. Please reference our sizing guide before ordering. An optional written appraisal can be added from the drop-down menu (non-refundable once completed).
