Cubic Zirconia Gems
Cubic Zirconia and Lab-created Gems
Man-made cubic zirconia and lab-created gems - for use with Art Clay Silver or other Metal Clays - and lampworking. Can take the high temperatures of firing. Gem grade. Mined gems generally have inclusions that can't take the heat of firing and crack - the lab-created gems are free from inclusions. Nothing to say that you couldn't use them with epoxy clay or polymer clay - or in more traditional gem setting uses too.
