Orthoclase set of 3 twin habits

Item Description

This is a very interesting set of sharp, single orthoclase crystals, all floaters. There is a normal single crystal, a Baveno twin (Ba), Mannebach twin (Ma), Carlsbad twin (Ca). This is a niec reference example in any case but I find it very interesting this collector was able to amass all types from a single locality, as well.
