Coloured stones for manufacture
Quartz, tourmaline, garnet and the wider family of coloured stones, in calibrated sizes and matched parcels. Treatment is stated where any exists: most citrine on the market began as amethyst and was heated, and the listings say so.
This is stock for jewellers and manufacturers rather than collectors: consistent colour, reliable supply, sensible pricing. Certification is provided where the value warrants it.
Shipped direct or deposited into vault storage, the same as everything else on the exchange.
