A very rare species, these were identified as Poldervaartite for several years before more intense and conclusive analysis confirmed them to be Olmiite. They are never fully transparent as the crystals are massive and not singly grained - we see them rarely and they are always snatched up. This one tends a bit more toward the yellow end of the of orange-yellow spectrum that these usually fall on.
