Microcline (Var: Amazonite), Albite (Var: Cleavelandite)
Small Cabinet, 7.8 x 7.5 x 5.1 cm
Lake George, Park Co., Colorado, USA
A SUPERB example of a Colorado "white cap" amazonite crystal, with a thin layer of white microcline at the termination that makes these so distinctive and desired by collectors. Even without the white cap, this is a great amazonite specimen, with fine robin's-egg blue color, but more importantly, a wonderful architectural form; it is a large compound crystal with terminations at 3 different levels. There is a sparing amount of microcline matrix present.. Large whitecaps like this are exceedingly uncommon and hard to obtain in good specimens!
