This is simply a superb octahedral crystal, of perfect form and classical colour, from the famous Göscheneralp of Uri Canton in Switzerland. It has definitely not best, but clear light pink colour, sharp form with almost no damage (minimal edge wear is all I can see under the microscope) and is complete 360 degrees around. Minor crystallized Quartz is attached to the bottom. A distinct cleaning could improve this fine specimen a bit more. In any case a stunning thumber in spledend condition.
