Specimens of this Australian locality are uncommon in the maket, but their beauty makes them stand out from the smoky quartz samples. It is very curious how these specimens nodules are found into rhyolitic matrix geodes called "thundereggs"; this vugs are usually covered by small milky quartz crystals, some amethyst... They are in themselves a treasure of Nature. In this specimen we a parallel growth, doubly terminated, of smoky crystals. Excellent transparency and smoky color zoning. On minor matrix. The main crystal is: 4,3 x 2,1 x 1,9 cm.
