Onyx Stones

Onyx (Onex Ratna) from ₹150 per carat, in black and green. Green Onyx is worn as the upratna for Emerald (Panna), for Mercury (Budh), usually on an astrologer’s advice. Onyx is chalcedony — an evenly coloured quartz that takes a high polish and holds up at Mohs 7, which is why it suits signet rings, men’s jewellery and everyday wear. Black onyx gives strong contrast in both silver and gold. Each stone comes with a lab report from an ISO 9001:2015-certified laboratory.
