Very large main crystal aesthetically perched on matrix, with a smaller, companion crystal that displays some skeletal growth features. Small dolomite crystals accent the matrix nicely. These larger crystals from here do not exhibit the flawless transparency that makes these referred to as "diamonds," however, the crystal is still extremely bright internally and displays flawless, glass like luster all around. In wonderful condition with only a small, shallow chip on the backside of the main crystal--this is visible in the video and is not visible from what I would consider the preferred display angle. This specimen can still be, however, displayed to advantage 360 degrees as the chip is small and shallow enough to not detract from any angle of display. Matrix specimens without repairs or reattachment of crystals are very rare from this location, especially in this size and quality. Main crystal in approx. 6.8 cm along it's longest edge and very nearly 10cm from bottom to top.
