A very nice group of lustrous, light brown, barrel shaped crystals growing on a matrix of terminated quartz crystals. The largest crystal is 1.5 cm in length. This cluster has the largest number of individual crystals I have seen in a specimen from Rhodope. There is some minor damage to the lower left periphery but this does not affect the overall quality of this exceedingly rich and attractive specimen. All in all, a very showy piece!
