Crafted in warm 14K rose gold vermeil over sterling silver 925, it is a bold, non-traditional engagement or anniversary ring for anyone who wants a little drama in their romance.

A study in fire and shadow
The appeal of this ring is contrast — the molten red-orange of the fire opal playing against the endless black of the onyx, all wrapped in rose gold that warms the whole palette. The emerald cut keeps the look architectural and clean, so the piece reads as modern even with its vintage soul. It sits comfortably among our gothic engagement rings for those who love dark-romantic jewelry, yet the rose gold keeps it soft enough for everyday wear.
The red fire opal
At the heart of the ring is a lab-created fire opal in a vivid, saturated red — a color that gives the stone its name and its glow. Fire opal is prized for exactly this warmth: a candle-lit flash that shifts as the light moves across the emerald-cut facets. The lab-created origin means a consistently rich, clean color at a friendly price, so the drama of a fire opal comes without the fine-jewelry premium. Opal is also the October birthstone, which makes this a thoughtful pick for autumn birthdays — our October birthstone guide explores the lore in full.
A frame of black onyx
Flanking the fire opal is natural black onyx, a form of chalcedony treasured for centuries for its uniform, mirror-deep black. Around 6.5 to 7 on the Mohs scale, it is durable enough for daily wear and polishes to a glassy sheen that makes the opal’s fire look even brighter by comparison. If the jet-black stone is what draws you, explore more of it across our black onyx engagement rings, and read why couples are drawn to it in our guide to black onyx meaning.
14K rose gold vermeil over sterling silver 925
The ring is made in 14K rose gold vermeil — a generous layer of real rose gold over a solid sterling silver 925 core. It gives you the rich, blush-gold warmth that flatters the fire opal and onyx alike, at a price that leaves room for the moment rather than the markup. The slim 1.6 mm band keeps the focus firmly on the stones.
What fire opal and onyx symbolize
Fire opal has long been linked to passion, energy and creative spark, while black onyx is the classic stone of strength, grounding and protection. Together they make a fitting emblem for a love that is both fiery and steady — which is part of why dark gemstones keep finding their way into meaningful jewelry. Our guide to black gemstones looks at the symbolism in depth, and you’ll find matching pieces in our black onyx couples rings.
