This is a rare style of crystallized gem aquamarine from Brazil, from a time before gem crystals from Pakistan were available and still distinct to the eye today for both form and color. A magnificent and totally gem transparent Brazilian aquamarine from the "old days" of mining in Brazil, showing a classic old style of color and form that we do not see today from anywhere. It is pictured in the classic book Precious Stones and Minerals (1970) by Professor Dr. Hermann Bank of Idar-Oberstein, and it was in his collection until exchanged out by Bill Larson & Peter Bancroft in the late 1970s. It has a wonderful complex termination - actually two different terminations - and was painted in ideal form for this book from 1970, as you see in the attached photo. Obtained by Bill Larson from his purchase of most of the Professor Dr. Hermann Bank collection in Idar, and where most specimens dated from the early 1900s-1960s; he kept it for his long held private collection of beryls that has been on display in the company store since the 1970s. 131 grams.
