Dark romance, bound in gold. This Celtic knot black onyx ring set centers a pear-shaped natural black onyx — deep, jet-black and softly elongated — cradled in flowing Celtic knotwork and cast in warm 14K yellow gold vermeil. It is a gothic bridal set built on ancient symbolism: the interlaced knots have no beginning and no end, a fitting emblem for a love meant to last.

Ancient knotwork, modern drama
The knot has been carried through Celtic art for over a thousand years as a symbol of eternity — a single unbroken line woven back on itself. Here it wraps the pear-shaped onyx like a crown, giving the ring a medieval, fantasy-inspired presence that stands apart from anything conventional. It is a design made for those drawn to gothic engagement rings and the beauty of the alternative altar. For a wider look at the aesthetic, our feature on gothic wedding rings and dark-romance styles is full of inspiration.
The engagement ring
Holds the pear-shaped black onyx inside sculpted Celtic knotwork — the dramatic focal point of the set.
The matching band
A contoured band carved with a Celtic trinity knot, shaped to nest against the engagement ring. Beautiful together, or worn alone from our gothic couple rings.
The natural black onyx
Black onyx is a natural chalcedony, treasured for its deep, even, glossy black and its cool weight in the hand. The pear cut — rounded at one end, tapered to a graceful point — gives the stone an elongated, regal silhouette that draws the eye immediately. To understand the lore behind the stone, our guide to black onyx meaning is a wonderful read.
Warm 14K yellow gold vermeil
The set is finished in 14K yellow gold vermeil — a rich layer of real gold over a core of sterling silver 925. Against the jet-black onyx, the golden tone creates a bold, high-contrast look that feels both antique and utterly current. It is the warmth of gold that turns gothic drama into something wearable every day.
What the Celtic knot symbolizes
Celtic knots represent infinity, eternity and the unbroken connection between two souls — the interlaced paths that cross and return without end. Paired with black onyx, a stone long linked to strength and protection, the set becomes a talisman for a bond that endures. If dark romance is your story, you will find kindred pieces across our black onyx engagement rings, and our history of Victorian gothic engagement rings traces where this romance began.

Frequently asked questions
Is the black onyx natural?
Yes. The center is a natural black onyx, a genuine chalcedony polished to a deep, glossy jet-black. Its rich, even color is a hallmark of the stone.
Does this come as a set?
Yes — it includes the Celtic knot engagement ring plus a matching contour band carved with a trinity knot, designed to nest together as a cohesive bridal set.
What is yellow gold vermeil?
Yellow gold vermeil is real gold layered over sterling silver 925 — the warm, golden look of gold at a much easier price. If you would prefer gold all the way through, the same design is also available in solid gold.
What does the Celtic knot symbolize?
Celtic knots represent infinity, eternity and unbroken connection — a single line woven with no beginning and no end. It makes the design especially meaningful for an engagement or wedding.
What cut is the center stone?
A pear cut — rounded at one end and tapered to a point — for an elongated, regal silhouette. The center weighs approximately 1.4 ct.
What are the accent stones?
Small simulated diamonds are prong set into the design, adding a crisp flash of white sparkle that lifts the dark center and the golden knotwork.
Can I wear this as a gothic engagement ring?
Absolutely. It is designed as a gothic, alternative bridal set and works beautifully as a non-traditional engagement ring, promise ring or dramatic statement piece.
