About the Item
Offered loose for collectors and bespoke fine jewelry, this 10.20 carat Ethiopian black opal displays a dramatic, shifting play of color with lively flashes of red, green, blue, and yellow that change under different lighting. Presented in a refined rectangular oval outline, the stone has strong visual presence and rarity value, making it an exceptional addition to a curated gemstone collection. Curated by Merkaba Jewelry Beverly Hills, it is a striking example of opal’s natural artistry and collectible appeal.
Ethiopian Black Opal Rarity and Beauty
Ethiopian black opal is prized for its vibrant color patterns and dynamic fire. In this size range, a high quality stone becomes increasingly scarce, especially one with pronounced multicolor movement and an elegant outline suitable for fine custom design.
Design Your Dream Jewelry
Offered unmounted, this gemstone is an ideal centerpiece for a bespoke creation through our Design Your Dream service. Consider:
A bold cocktail ring in platinum with diamond accents
A statement pendant designed to maximize color play
A collector focused design with minimal metal to keep the opal as the hero
Our team can advise on setting style, protective design choices, and accent stones that complement the opal’s color spectrum.
