I think I have caught most of the Glen Lehrer shows. The Lehrer pieces on the web are pretty much the collection put together by Glenn Lehrer exclusively for Gems. I think Glen Lehrer has trained a couple of Steven Bennet's cutter's to be able to do the torus ring cut while Glen picks out the stones and has final say on designs etc. Have to say Gems if you're reading this I don't think you market this collection well - it doesn't seem easily clear from the web that each piece is a limited edition and the ring/pendant you buy will be numbered and have Glenn Lehrer's specific stamp in it.
Gems did have other torus cuts, ceylon sapphire and paraiba tourmlaine spring to mind, some of which were loose stones ready for mounting, others set in torus rings and pendants - a beautiful purple sapphire torus cut set in a ring springs to mind.
Gems also sold other Lehrer pieces, I picked up a rather lovely amethyst pendant, some of them like angel wings were pendants ready to be set, very extravagent necklaces and a couple of sculptures I think.
Steve has said on air that he'll put more Glenn Lehrer pieces on air towards the end of february early march and that he hoped to bring some "torus" earrings to air in about the same period. Time will tell.....
Hope that helps
