But David just did a pretty good image of 2 that I got from Miss J recently...these are 8mm beads.

Am not sure, but I don't think Floor was able to find information in Czech Republic on saphiret...possibly the formula is lost. It is thought that gold (metal oxide?) was used in the process...

Anyone truly interested in saphiret should own at least one example, in my opinion, to at least preserve awareness of this awesome glass.

Saphiret glass is noticeably quite heavy.
