The rare coper mineral Kobyashevite was discovered and described in 2011. A close relative of Devilline this Copper Sulfate specie was an exciting find at Mina Ojuela this year, and in this deposit the specimens are impressively large and attractive, certainly the worlds best. It seems that these specimens are postmining redepositions and are always partly overgrown with small needles of clear Selenite. The best examples have a rich blue-green or Turquoise
color and when this is deposited on calcite crystals these have a very esthetic presentation. This specimen is in excellent condition and is the most attractive I have seen from the find. A choice and colorful rarity.
