Brookite Amazonite but what makes them so

but what makes them so rare and special is the fact that you have a native metal replacing a mineral that contains that metal

Specimen # BOL711B143

An attractive soft white color (with VERY pale minor blue-green highlights) crystal of Microcline from Adam Sotomayor's locality

which gives way into a thin pale blue-green zone

The piece was rather difficult to photograph

Brookite Amazonite but what makes them soBeautiful, sharp, fine quality, lustrous, gemmy, rich orange red colored Brookite crystals measuring up to 1. 1 cm are aesthetically set atop contrasting host rock matrix. As you can see, the Brookites feature the same classic black "phantoms" that are so desirable in specimens from the European Alps. No damage to the Brookites and it's not very often that one finds such superb eye catching examples of the species in near full size cabinet display
