An amazing sculptural cocktail ring, created in England during the modernism period, back in the 1970. The ring has been carefully crafted with geometric round patterns in solid yellow gold of 18 karats with high polished finish. The design of the ring was made in three dimensions like a spiky basket, which is holding on top a blue Chrysocolla. Chrysocolla: Mount in the center in multiple prongs settings, with 1 round cabochon cut (10 x 10 x 6 mm) of a natural Chrysocolla of about 3.5 carats. Weight: 9.2 Grams, (5.90 Dwt). Size: 6.5 and can be sized on a special request. Measurements: 20 mm by 20 mm (0.79 x 0.79 Inches) and raise 12 mm over the finger. Hallmarks: Stamped with the maker's mark, the mark for the assay of the 18kt gold and signed, "DJS .750". Very good conditions. Upon Request, Auction House may provide ring resizing or/and appraisal. This will carry an additional cost. Appraisals are made by our in house GIA certified Gemologist.
