Kite Cut Opal Engagement Rings

A kite cut opal engagement ring can be worn daily with the right setting and care, though opal is softer at Mohs 5.5–6.5 — the softest stone in the kite range. A protected bezel setting that shields the points is strongly recommended, and the ring should be kept from hard knocks, heat, and harsh chemicals. For a harder colorful option, see our white gemstone jewelry collection.

Each kite cut opal engagement ring is unique because every opal displays its own natural play-of-color — the shifting flashes of blue, green, violet, and fire are never the same from one stone to the next. The kite cut frames that individual color play in a distinct geometric window, making every ring genuinely one of a kind. Explore the full kite cut engagement rings collection.

A bezel or protected setting is best for a kite cut opal engagement ring, because it shields both the stone's surface and the cut's vulnerable points — important given opal's softer Mohs 5.5–6.5 hardness. Bezel settings wrap the opal in a protective metal rim while still showcasing its play-of-color. See our jewelry care guide for wear and care advice.

Three. 925 sterling silver is a solid alloy of 92.5% silver and 7.5% copper, so the metal is the same all the way through. 14K gold vermeil is a 2.5 micron layer of 10K-or-finer gold bonded over that same sterling base, which is the standard the US FTC sets for the word. Solid 14K gold is 58.5% pure and stamped 585, and this collection carries it in both rose and white.

Opal sits at 5.5 to 6.5 on the Mohs scale. For comparison, quartz is 7, emerald and aquamarine are 7.5 to 8, topaz is 8, sapphire and ruby are 9, moissanite is 9.25, and diamond is 10. Opal is hydrated silica rather than a hard crystalline mineral, so it takes knocks and sudden temperature change less well than any of those. That is the whole argument for a protective setting, and it is why the designs here shield the center stone.

Lukewarm water, a drop of mild soap, and a soft cloth. Dry the piece completely before you put it away. Never use an ultrasonic cleaner on opal, and keep the ring away from heat, sudden temperature change, and harsh household chemicals. Store it apart from harder gemstones so nothing scratches the surface. Our jewelry care guide sets out the routine for each metal in this collection.

Black onyx, emerald, and topaz, depending on the design. Onyx is a chalcedony at Mohs 6.5 to 7 and frames the opal in flat, deep contrast. Emerald is a beryl at 7.5 to 8, and its green picks up the cooler flashes inside the stone. Topaz sits at 8 and reads brighter and cleaner. All three are harder than the opal itself, so they carry the shoulders of the ring while the softer center stone stays protected.

Solid gold pieces are made to order, which takes three to six weeks from the day the order is placed. The sterling silver and 14K gold vermeil designs on this page ship from stock. Non-customized pieces carry a 14-day return window, so there is room to see the play-of-color in person before deciding. The solid 14K rose gold set here is the same silhouette as its vermeil counterpart, cut in solid metal.
