Pedial faces are often shining but other faces may be somewhat dull and frosty. Berborite-2H shows a characteristic perfect {001} cleavage. Sometimes hollow cores are seen. Berborite-1T and -2T occurred in cavities in "spreustein" (massive fibrous natrolite) together with böhmite, thomsonite, chlorite, etc. Berborite-2H was found in analcime vugs lined with fibrous aegirine together with natrolite, fluorite, and calcite, and as a rarity in spreustein druses together with gibbsite. | ||||||||||||||||
