Manganoan Calcite (rare locale - fluorescent) John White Coll.

Item Description

Documented specimens of ANY species are RARE from this end of the St Gotthard Highway tunnel. This is a brilliantly lustrous, sharp single complex rhomb of manganoan calcite with origins, according to its old label, from the tunnel project here in the St Gotthard pass. The rhomb is a light pastel-pink. A very rare locality specimen, and a good calcite crystal as well! Ex John White Collection. Value of such a rarity???
