This is some old hippie stuff right here - you don't see many any more. It's a 6 sided natural master that measures approx 3" long and 7/8" across at the widest point. The crystal has all the natural inclusions that Mother Nature put in there so if you are looking for some fake man made perfect glass please move along - this is not your listing to buy. On the point there are a few small flea bites - I've had and wore this one for many years. The fimo I suppose could be taken off but it's pretty hard now and very secure on the crystal. It's strung on a soft woven silk cloth string that simply slips of your head. It's 30" long so plenty of room. It (the crystal) weighs 278 cts - 1.96 oz or 55.6 grams if that helps you figure out how big it is. Those weights do not include the string. It is of course the only one I have. I hope it will go to a good home.
