Description from the seller
Brooch in 750/18 K yellow gold. The brooch is designed as a half-moon or rather moon-sickle. In ascending and descending sizes, a total of 9 Australian solid opals in the most beautiful colorful hues are set. Together, the crystal opals amount to approximately 3.50 ct. Inside, the opals display all the colors of the rainbow. Notably, blue and green shades stand out. Alongside, many red color reflections are mixed in. Especially on dark backgrounds, the colors appear more vivid, diverse, and radiant. Australian gem-class opals of the finest quality.
In the inner semicircle, 8 diamonds with a total of 0.10 ct. (F/VVS) are set in brilliant cut, enhancing the design of this high-quality goldsmith work.
