1970s Black Opal Ring
Enchanted 1970s statement ring with a superb Lightning Ridge black opal. Displaying vivid blues and greens with the occasional flash of purple and red, the stone shows stunning play of colour as the light moves across the surface. The body is a deep blue-black and small splodges of the red ironstone matrix show through at the surface. The 18 carat gold ring has been built around the stone, with abstract organic - almost eel-like - forms and a scattering of tiny, ice-white diamonds that glisten like dew. Openwork and rough, rock-like textures decorate the shoulders and the K18 stamp inside the band indicate that it was made in Japan.

Condition
We offer detailed and accurate condition reports on each listing. These pieces are antique, vintage, or pre-loved and often over 100 years old so they're going to have lived a life. A healthy patina and the odd scuff or scrape is quite normal... it's part of their charm! Everything we present has been checked over by our jeweller and should be good for wear for many years to come (unless otherwise stated) but please remember to treat them with appropriate care and consideration for their age.
