4mm Ruby red coloured Cubic Zirconia Gem stones. Only a trained eye can differentiate between a Cubic Zirconia and a diamond. These gems are such high quality that they can be fired into silver clay without the colour being affected. As well as firing in a kiln, gems of 5mm diameter or less can be fired on a gas hob or with a blow torch.
All these fireable gemstones are round in shape and multifaceted to reflect light on all their faces. Sold individually
