This \u003cstrong\u003ecoffin cut ruby engagement ring\u003c\/strong\u003e centers a 2.1-carat AAA lab-grown ruby — a genuine ruby with deep, saturated color — in a striking elongated coffin cut, cradled in a six-prong basket. Clusters of natural black onyx trinities flank each shoulder, turning a classic red-stone ring into something sharper, darker, and unmistakably modern. Cast in 14K rose gold vermeil over sterling silver 925, it is built for the bride who wants a ring nobody else is wearing.\u003c\/p\u003e\n\n\u003cdiv class=\"feature-pills\"\u003e\n\u003cspan class=\"pill\"\u003eGenuine lab-grown ruby\u003c\/span\u003e\n\u003cspan class=\"pill\"\u003eCoffin cut · 2.1ct · 7×10mm\u003c\/span\u003e\n\u003cspan class=\"pill\"\u003eNatural black onyx trinities\u003c\/span\u003e\n\u003cspan class=\"pill\"\u003eSix-prong basket\u003c\/span\u003e\n\u003cspan class=\"pill\"\u003e14K rose gold vermeil\u003c\/span\u003e\n\u003cspan class=\"pill\"\u003eFree velvet gift box\u003c\/span\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eThe genuine lab-grown ruby\u003c\/h2\u003e\n\u003cp\u003eThe center stone is a AAA-grade lab-grown ruby — a real ruby, the red variety of corundum, chemically and physically identical to a mined one. It carries the same deep, blood-red color that defines fine ruby, the same crystal structure, and the same Mohs 9 hardness, second only to diamond, which makes it superbly suited to daily engagement-ring wear. Grown rather than mined, it delivers vivid, consistent saturation at a full 2.1 carats without the natural-ruby price tag, and with clean, ethical origins. Ruby is the July birthstone and the 15th and 40th anniversary gem, giving the ring meaning far beyond its drama.\u003c\/p\u003e\n\n\u003ch2\u003eThe coffin cut and setting\u003c\/h2\u003e\n\u003cp\u003eThe coffin cut is an elongated hexagonal step cut — geometric, architectural, and strikingly different from a standard oval or pear. Measuring 7 × 10 mm, the stone lies long on the finger, and a six-prong basket holds its elongated shape securely from every angle. The clean rose gold metalwork stays deliberately quiet so the contrast between red fire and black shadow does all the talking. It is a shape with real symbolism behind it, at home among alt-bridal and gothic engagement rings.\u003c\/p\u003e\n\n\u003ch2\u003eThe natural black onyx accents\u003c\/h2\u003e\n\u003cp\u003eSix natural black onyx accents cluster three to a side, set as small trinities of pear and round cuts at each shoulder. Black onyx is a natural chalcedony with a deep, opaque, velvet-black surface — the perfect foil to the ruby’s red fire. The onyx is genuine and naturally dark, never dyed, and its shadow makes the center stone burn brighter. The red-and-black story runs through our black onyx engagement rings and black onyx couples rings.\u003c\/p\u003e\n\n\u003ch2\u003eMeaning and symbolism\u003c\/h2\u003e\n\u003cp\u003eRuby has stood for passion, vitality, and courageous love for millennia — the boldest red in the gem world, worn by royalty as a talisman of power and devotion. Black onyx has been used in rings and amulets since ancient Greece, traditionally tied to strength and protection. Together they make a ring about fierce, protective, wholehearted love. To read more about the dark stones at its shoulders, see our journal on black onyx meaning, our black gemstones guide, and our guide to black rings for women.\u003c\/p\u003e\n\n\u003cp class=\"lead-paragraph\"\u003eAquamarise vermeil is real gold over sterling silver 925 — the rich, golden look you love, at a price that makes it easy to say yes.
