Soft, sectile mass of Acanthite with many crude forms of cubic crystals. The cluster at the tip is 7mm across. The specimen comes from the historic cobalt/silver Keeley-Frontier mine located in one of the largest silver mining districts in the world. The mine produced an incredible 3.3 million pounds of cobalt and 19.1 million ounce of silver. There is associated Calcite in mass and as crystals, a clear indication that the specimen was never etched.

Babanekite is the copper member of the Vivianite group. It's fun to look at these minerals as they all look the same just different colors. Babanekite was described in 2012. The crystals on this specimen are less than 0.3mm and are pink, not green as you would think. It probably contains small amounts of cobalt. From Dr. Hyrsl Jaroslav's stock.

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).
