Description

A small zone in the 2017 finds of borates had some grey inclusions in calcite - we have not identified that material yet. This is a piece fromthat area with sharp olshanskyite, roweite and a few unknowns. As you can see in the close up there are also tiny white crystals sticking up from the olshanskyite - not identified yet either,,, we have around 20 samples of these finds in the lab for analysis at the moment and will share the information publically as soonas we have a chance, Meanwhile this is your opportunity to obtain an intersting one from the complex zone and have a good olshanskyite as a bonus,
