Stone - As is the beauty of Opals, the stone is different in different lights. Mainly, it is very dark / almost black looking until it catches the light and has Green Opalescence / Fire and also some Royal Blue and Turquoise Highlights, and sometimes, also red / orange.
Bought as a "vintage" item about 30 years ago. The Jeweller told me that that though small, it was expensive because Black Opals are the rarest / most precious opals. Also the fact that is set in 8ct gold fittings shows it is a valued gemstone. Chain is an 18ct Yellow Gold Hallmarked 1mm Diamond Cut Belcher.Weight = 1.50 grams approx. Length = 18 / 45cms. Purity - 18 carat gold Hallmarked 750. Comes in the Black Necklace Box as shown. This item is in the category "Jewellery & Watches\Fine Jewellery\Necklaces & Pendants".
