I have cut sugilite rough similar to most of the types shown in tne necklace picture. In the late 1990's I attended a show and saw hundreds of strands of reconstructed sugilite and vowed never to cut it again and frankly I have not missed cutting it. It can be wonderfully complex and exquisitely gemmy but authenticity issues are paramount to me as a stone cutter. If I were a bead collector I believe I might have a far different attitude considering that a vast amount of stone beads are etched, dyed , filled etc and they are very important to the trade and their provenance is largely unquestioned , jade beads being a perfect example.
