This is one of the bigger Boleite crystals you will ever see. IT is a whopping 1cm on edge with a number of smaller crystals. They don't get much bigger than this according to the Mineraolgical Record: Special Issue #1 (Mexico) January-February 1998 Volume 29 Number 1, page 38 under the description of Boleite the author states that "Cubic crystals of millimetric size (up to 5 mm) have been found in abundance, while those approaching a centimeter are very rare. Crystals of larger size (the record being 2.5 cm) are highly exceptional.....
Though the one corner has a small ding the price has been adjusted accordingly. Large crystals of Boleite like this are seldom seen on the market and one little ding should not distract from its overall beauty. Must be insured and extra shipping will apply. Ex Carter Rich (see Prov. tab).
