Opal lovers alert! A perfectly round, high dome cabochon of Australian black opal in the most beautiful, vivid blues and greens, with a crown of fine quality accent diamonds. The opal shows terrific play of color, & with magnification there is a bit of internal crazing that does NOT break the surface on either side, and is not visible when worn. I added extra diamonds going up the arms of the infinity pendant for more sparkle; my pics show the before and after. This opal displays all variations of blue and green: cobalt, turquoise, electric neon green, teal, ocean blue, sky blue, grass green, etc. It looks esp AMAZING on people with yellow, olive, or neutral undertones in their skin! Pendant only. I also have a 19-inch 14K yellow gold box chain available to add on for $250! ⚜️ 🦋 One 7 x 7mm round opal cabochon at 1.10 carats 🐠 Diamonds; SI/1 and G-I 🌀 15/16 inch x 7/16 inch (23.8 mm x 11 mm) ☘️ Hallmark: C in a circle 🔷 Weight 2.62 grams 👗 Tests 14K yellow gold Tags: October birthstone, birthday, Lightning Ridge, NSW, blue opal, beauty, color change, color shift, electric eel, diamond necklace, vintage, slide, Catbird, Jacquie Aichie, Logan Hollowell, Meira T, Anne Sisteron, The Last Line, Ring Concierge, Noemie, Adina Reyter, EF Collection, Mejuri, Dana Rebecca, Nouvel Heritage, Bony Levy, Roberto Coin, Marco Bicego, Zoe Chico, Sydney Evan, Ippolita, VCA, Van Cleef, Foundrae, Tiffany, Effy, LeVian, Gorjana, necklace stacks
