Description

Here we have an interesting specimen from Brazil. This piece which is developed as a floater has a base of intense green celadonite in the center out of which several quartz crystals are poking out in all directions. The quartz shows a unique way of crystalisation and exhibits a smooth rose-pinkish colour. One of them even has a "hat" of lustrous and clear quartz on top which makes this example even more unique.
