SHARP crystals to 4.5 cm, partially included by and altering to Meyerhofferite on their edges for a unique visual contrast to the cores, dominate either end of this beautiful matrix specimen. In person it is much less brown and more white and clear...but photos simply do not do these justice: these crystals are so clear, that the small bit of underlaying brown matrix simply is all you see in the photos sometimes. Not so, in person.
