Natrolite Sgurr nam Fiadh, Isle of Skye, Scotland, UK 8cm x 4cm x 3cm Crystals of Natrolite found in a very large gas cavity in a weathered boulder. The greenish background (altered basalt) is distinctive and Prof. M.F.Heddle in his famous book ’Mineralogy of Scotland’ (1901) describes Scolecite from this locality on a similar coloured background. But this stuff is definitely Natrolite, it was tested via Alan Dyer in 2002. A mystery perhaps? Self-collected 1994. (Author: Mike Wood)
