Ancient symbolism, dressed in shadow. The Celtic Knot Mystic Topaz ring set weaves interlacing knotwork around a pear-cut mystic topaz that flashes violet, teal, green and magenta as your hand moves. Crafted in solid 925 sterling silver and finished in deep black ruthenium, this two-piece set fuses old-world Celtic artistry with gothic drama — an alternative engagement ring for lovers of the dark.

A Celtic, gothic proposal
Flowing Celtic knots form a crown-like setting around the center stone, their interwoven lines representing eternity, unity and paths forever entwined. Cast in blackened silver, that knotwork turns to deep architectural shadow — a fantasy-inspired, gothic silhouette that stands apart from any conventional solitaire. It belongs among our gothic engagement rings and topaz engagement rings, with the same interlaced-love spirit running through our topaz couples rings.
The engagement ring
Holds the pear-cut mystic topaz (approx. 1.4 ct) in a Celtic-knot crown flanked by simulated diamonds — the statement piece and focal point of the set.
The matching band
A curved band that mirrors the knotwork of the engagement ring, nesting beautifully alongside it to complete the cohesive bridal silhouette.
The mystic topaz center
The centerpiece is a pear-shaped mystic topaz — genuine natural topaz finished with a permanent iridescent coating that scatters rainbow tones of violet, teal, green and magenta across the stone. The underlying gem is real topaz, one of the harder gemstones at Mohs 8, so this rainbow drama is far more wearable than most colored alternatives. The pear cut lengthens the finger and shows off the stone’s dynamic color play, which shifts with every angle of light. To place topaz in the wider world of gemstones, our history of gemstones guide is a fascinating read, and topaz lovers born in winter will enjoy our December birthstone guide.
Simulated-diamond accents
Precision prong-set simulated diamonds (crisp cubic zirconia) accent the knotwork, adding bright white fire that makes the topaz’s rainbow tones read even more vividly. It is a brilliant, budget-friendly way to layer in classic engagement-ring shimmer, and the sparkle against blackened silver is what gives this set its edge. Prefer a lab-grown diamond or moissanite accent instead? Message us — most of our designs can be upgraded.
The black ruthenium finish
The set is finished in black ruthenium, a rare precious metal from the platinum family, applied over solid 925 sterling silver. Ruthenium reads as a deep, smoky gunmetal — a rich blackened-silver tone rather than a flat, pure jet-black. That is the beauty of it: instead of looking painted-on, the finish carries genuine depth and an antique, gothic-vintage warmth that brings out every line of the Celtic knotwork. It is a more precious, more durable finish than ordinary black plating or oxidized silver, and it lets a sterling silver ring wear like something far darker and more mysterious. Curious about the metal? Read what is black ruthenium.
What it symbolizes
The interwoven Celtic knot has no beginning and no end — a timeless emblem of eternal love and infinite connection — while the blackened metal speaks to mystery, strength and devotion. Together they make this set especially meaningful for engagements and milestones with a gothic soul.

Frequently asked questions
Is the mystic topaz natural?
Yes — the underlying gemstone is genuine natural topaz. Its rainbow iridescence comes from a permanent metallic coating on the surface, which is what gives mystic topaz its signature color play. The gem itself is real topaz, not glass or a simulant.
Is it pure black?
Not pure jet-black — and that is by design. Black ruthenium is a deep, smoky gunmetal, a rich blackened-silver tone. It carries real depth and an antique, gothic-vintage warmth that flat, painted jet-black finishes cannot, so the ring reads as dark and mysterious rather than one-dimensional.
What is black ruthenium?
Ruthenium is a rare precious metal from the platinum family. Applied over sterling silver, it creates a deep blackened-silver finish that is more precious and more durable than ordinary black plating or oxidized silver.
Will the rainbow color wash off?
No. The iridescent coating on mystic topaz is a permanent surface treatment and will not wash off with normal cleaning. Just avoid abrasives and harsh chemicals to keep the color play at its most vivid.
What metal is it made from?
Solid 925 sterling silver, finished in black ruthenium for its smoky gunmetal depth. It is real sterling silver, not a base-metal alloy.
Does this come as a set?
Yes — it includes the Celtic-knot mystic topaz engagement ring plus a matching curved band that mirrors its knotwork. The band can also be worn on its own as a promise or stacking ring.
What are the accent stones?
Precision prong-set simulated diamonds (cubic zirconia) that add crisp white fire and make the topaz’s rainbow tones read even more vividly. Prefer lab-grown diamond or moissanite accents? Reach out and we will tailor it.
Will the finish wear off?
Black ruthenium is a precious-metal finish from the platinum family, more durable than black PVD or oxidized silver. With gentle care — removing it for showers, swimming and lotions — it keeps its rich, smoky depth. If it ever needs refreshing down the line, we are happy to help.
Is it durable enough for daily wear?
Yes. The topaz sits at Mohs 8, making it more durable than opal, pearl or moss agate, and sterling silver is a firm, wearable metal. Remove the rings for rough activities to keep everything pristine.
How do I care for the rings?
Remove them before showering, swimming or applying lotions and fragrance, store them in the velvet box, and buff gently with a soft dry cloth. Gentle care keeps both the topaz and the blackened finish luminous.
What size should I order?
Select your ring size at checkout. The band is comfort fit. If you are unsure or between sizes, contact us for guidance. Resizing is available and starts from a modest fee.
Are the stones ethically sourced?
Yes. All of our stones are ethically sourced and conflict-free, so you can wear your set with complete peace of mind.
