This \u003cstrong\u003eblack onyx engagement ring\u003c\/strong\u003e centers an emerald-cut lab-grown blue sapphire framed by natural black onyx accents in trillion, round and leaf-bezel cuts, all on an art deco setting in solid 925 sterling silver with a rhodium finish.

It appears in a deliberate arrangement: two trillion cuts flanking the center stone, two round accents set within leaf-shaped silver bezels at the crown and base, and a cluster of six round accents flowing down the shoulders. That much true black around a blue center is what creates the ring's signature gothic-bridal look — no white-diamond halo, just contrast. Explore more of the palette in our black onyx engagement rings collection, and read the lore in our guide to black onyx meaning.\u003c\/p\u003e\n\n\u003ch2\u003eThe lab-grown blue sapphire center\u003c\/h2\u003e\n\u003cp\u003eThe center stone is a \u003cstrong\u003elab-grown blue sapphire\u003c\/strong\u003e — and that means a genuine sapphire. It is real corundum, the same mineral as mined sapphire, with the same chemistry, the same deep-royal ceylon-blue color and the same exceptional hardness of 9 on the Mohs scale, second only to diamond. Lab-grown simply describes where the crystal formed: in a controlled environment rather than underground. It is not a simulated or imitation stone; it is sapphire through and through, making it superbly durable for daily wear on an engagement ring. At 8.0 x 6.0 mm and roughly 1.4 carats, the emerald cut spreads wide and reads larger than a comparable round.\u003c\/p\u003e\n\n\u003ch2\u003eThe emerald cut\u003c\/h2\u003e\n\u003cp\u003eAn emerald cut is a rectangular step cut with truncated corners and long, parallel facets — chosen when a stone's color is the point and sparkle should not compete with it. For a sapphire this saturated, that is exactly right: the deep royal blue reads cleanest in a long, open rectangle, and the silhouette visually elongates the finger. It is the calm, confident foundation the black onyx accents build around.\u003c\/p\u003e\n\n\u003ch2\u003eThe art deco leaf-bezel framework\u003c\/h2\u003e\n\u003cp\u003eThe setting is pure art deco — the 1920s language of geometry, symmetry and small architectural detail rather than freeform ornament. You see it in the rectangular emerald cut, the mirrored placement of accents across the cardinal points and shoulders, and the leaf-shaped silver bezels at the crown and base that read as delicate lotus or fleur-de-lis flourishes. The overall silhouette feels vintage and heirloom without tipping into costume — right at home among our gothic engagement rings. To see where the aesthetic comes from, our feature on Victorian gothic engagement rings is a rich read.\u003c\/p\u003e\n\n\u003ch2\u003eSolid sterling silver with a rhodium finish\u003c\/h2\u003e\n\u003cp\u003eThe ring is solid 925 sterling silver — 92.5% pure silver throughout, not plated base metal — finished with rhodium, the same precious metal used on fine white gold. That rhodium layer gives the band a bright white-gold-style luster and adds scratch and tarnish resistance, and the white-metal tone is the perfect backdrop for the royal blue and deep black to read at their sharpest. Genuine 925 sterling silver will not turn your skin green; that reaction comes from low-quality base metals, not real sterling.\u003c\/p\u003e\n\n\u003ch2\u003eHow to wear it\u003c\/h2\u003e\n\u003cp\u003eBuilt as an engagement ring, it doubles as a serious promise ring, a September birthstone piece (sapphire is the September stone), or a bold right-hand statement. It stacks beautifully with a curved or chevron contour wedding band — the cardinal-point onyx at the base of the setting gives a contour band a natural nesting line. Couples who want the theme across two hands can browse our black onyx couples rings, and for wedding-day styling our edit of gothic wedding rings and dark-romance styles is full of ideas.\u003c\/p\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cdiv class=\"spec-card\"\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMetal\u003c\/strong\u003e Solid 925 sterling silver with rhodium finish\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter stone\u003c\/strong\u003e Lab-grown blue sapphire (genuine sapphire), emerald cut\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter size\u003c\/strong\u003e 8.0 x 6.0 mm (approx. 1.4 ct)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter hardness\u003c\/strong\u003e 9 on the Mohs scale\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter color\u003c\/strong\u003e Deep royal blue (ceylon tone)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccents\u003c\/strong\u003e 10 natural black onyx (2 trillion, 2 cardinal round, 6 shoulder round)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSetting\u003c\/strong\u003e Art deco, four double-prong claws, leaf-bezel detail\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBirthstone\u003c\/strong\u003e September; 5th and 45th anniversaries\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSourcing\u003c\/strong\u003e Lab-grown sapphire (no mining); natural onyx ethically sourced\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded\u003c\/strong\u003e Free luxury velvet gift box \u0026amp; lifetime warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eSizing \u0026amp; care\u003c\/h2\u003e\n\u003cp\u003eTrue to size.
