Black Onyx Engagement Rings

About

A black onyx engagement ring features a deep black chalcedony center stone — opaque, polished to a glassy mirror finish, and historically associated with strength, protection, and grounded commitment. Black onyx sits at a specific intersection: it's one of the few genuinely opaque jet-black gemstones available at engagement-ring scale, hard enough for daily wear, and priced accessibly enough to allow generous stone sizes that other dark materials would make cost-prohibitive. This collection covers every black onyx engagement ring Aquamarise® makes — solitaire, halo, hidden halo, three-stone, vintage, and gothic-inspired settings in sterling silver, gold vermeil, and solid 14K white, yellow, and rose gold. Wherever possible, we source recycled precious metals from certified refiners. For black onyx in matching ring pairs designed for partners, see black onyx couples rings .
