St Christophe-en-Oisans, Bourg d'Oisans, Isère, Rhône-Alpes, France Crichtonite is a very rare, complex oxide containing a number of rare earths. This is surely an old piece, as it comes from the now defunct old workings of the TYPE LOCALITY in Isere. This piece features sharp crystals of up to 2 mm, on contrasting matrix, and they are readily visible. 6 x 4.6 x 3.2 cm. |
