Royal blue, framed in midnight. The Aurelia blue sapphire and black onyx ring sets a 6×8mm oval lab-grown blue sapphire — a genuine sapphire with deep, saturated color — in a milgrain bezel, flanked by two trillion-cut natural black onyx and lifted by simulated diamond accents at the crown and base. A twisted leaf-vine band finishes it with soft, nature-inspired texture. Cast in 14K rose gold vermeil over sterling silver 925, it is a vintage-romantic take on the most storied colored stone in bridal history.

The lab-grown blue sapphire center
The center stone is a 6×8mm oval lab-grown blue sapphire — a real sapphire, chemically and physically identical to a mined one, with the same vivid royal-blue color and the same extraordinary hardness of 9 on the Mohs scale. Grown rather than mined, it offers traceable, ethical origins and beautifully consistent saturation, at a fraction of the cost of a natural sapphire of the same size. Blue sapphire has been the most recognizable colored engagement stone for generations, from royal jewels to modern proposals — a color that reads classic, regal, and quietly confident.
The trillion black onyx sides
On either side of the sapphire sit two trillion-cut natural black onyx, their crisp three-sided points aimed toward the center. Black onyx is a natural chalcedony with a deep, glossy jet-black surface, and that darkness makes the royal blue glow even brighter — a bold two-color pairing rather than a single-color solitaire. It is a look at home in our black onyx engagement rings and in the darker, more romantic world of our gothic engagement rings.
Bezel, milgrain, and the leaf-vine band
The sapphire is held in a full bezel, the most secure setting there is — a continuous rim of metal that guards the stone’s edges with no prongs to snag. Around it runs milgrain, the fine beaded metalwork that defines Edwardian and Art Nouveau design, giving the ring its antique-romantic soul. The band twists from the setting into a sculpted leaf-vine pattern, tying the piece to nature-inspired styling. You will find the same craftsmanship across our black onyx couples rings.
The simulated diamond accents
Simulated diamond accents crown the top and bottom of the setting, adding a bright flash of white that completes the composition — the eye moves from those sparkling accents to the blue center to the black onyx sides. The simulated diamonds deliver classic engagement-ring brilliance while keeping the ring accessible.
Meaning and symbolism
Sapphire has stood for wisdom, loyalty, and faithful devotion for thousands of years, worn in royal and ceremonial rings as a symbol of enduring commitment; it is the September birthstone and the 5th and 45th anniversary gem. Black onyx brings its ancient association with strength and protection.

Sizing & care
Choose your size at checkout; if you are between sizes or unsure, reach out and we will help, with resizing available from a modest fee. Clean gently with warm, soapy water and a soft brush to reach into the milgrain and leaf detail, then dry with a soft cloth. Sapphire is exceptionally hard-wearing, but store the ring in the velvet box away from harder jewelry so the onyx and setting stay pristine.
Frequently asked questions
Is the sapphire real?
Yes. It is a genuine lab-grown blue sapphire — chemically and physically identical to a mined sapphire, with the same royal-blue color, the same 9 Mohs hardness, and the same brilliance. The only difference is that it was grown rather than mined, giving it traceable, ethical origins.
Is the black onyx natural?
Yes. Both trillion-cut side stones are natural black onyx, a natural chalcedony prized for its deep, glossy jet-black surface. It is never dyed or simulated in this ring.
Why choose a lab-grown sapphire?
A lab-grown sapphire gives you the same real sapphire in every meaningful way — identical hardness, color, and brilliance — with traceable ethical origins and beautifully consistent saturation, all at a far more accessible price than a natural sapphire of the same size.
What are the small accent stones?
The bright accents at the top and bottom of the setting are simulated diamond (cubic zirconia), chosen for crisp white sparkle that frames the blue center and keeps the ring accessible.
What is rose gold vermeil?
Rose gold vermeil is real 14K rose gold over sterling silver 925 — the warm, golden look of rose gold at an easier price. If you would like gold all the way through, the same design is also available in solid gold.
What is a bezel setting?
A bezel is a continuous rim of metal that wraps fully around the stone, the most secure mount available. With no prongs to catch on fabric, it protects the edges of the sapphire while giving the ring a smooth, refined look.
What does milgrain mean?
Milgrain is the tiny beaded line of metal along the edge of the setting, a signature of Edwardian and Art Nouveau jewelry. It gives the ring a vintage, handcrafted, antique-inspired character.
What is a trillion cut?
A trillion is a triangular, three-sided cut with sharp points. Set with the points facing inward, the trillion onyx create directional flow that draws the eye straight to the sapphire center.
Is this a good September birthstone gift?
Yes. Sapphire is the traditional September birthstone and the 5th and 45th anniversary gem, so the ring carries personal meaning as a proposal, birthday, or milestone piece.
Is sapphire durable enough for daily wear?
Exceptionally so. Sapphire is rated 9 on the Mohs scale, second only to diamond, making it one of the most scratch- and impact-resistant stones for everyday wear. The bezel setting adds even more protection around its edges.
What does sapphire symbolize?
Sapphire has symbolized wisdom, loyalty, and faithful devotion for thousands of years, worn in royal and ceremonial rings. Paired with the strength traditionally linked to black onyx, the ring speaks to enduring, committed love.
Can this ring be resized?
Yes, within reason. The bezel and milgrain detail add a little complexity, so we recommend ordering your correct size where possible; if you need help, contact us and resizing starts from a modest fee.
Does it arrive gift-ready?
Yes. Every order ships in a free luxury velvet gift box, backed by our lifetime warranty — ready for a proposal or to give as a keepsake.
