Also known as as Chatoyant, Velvet, or crystalline Malachite.  Truly unusual specimen:

  • The vast majority of Malachite forms as a secondary mineral.  That is, from the breakdown of other copper-bearing minerals
  • When Malachite forms as a primary, crystalline, mineral; the crystals are needle-like.
  • When closely-packed like these, they reflect light individually, but as almost parallel rods; like fiber-optics.

The yellow cube is a typical boullion-cube included for size reference only.  Specimen measures about 7cm x 4cm x 3cm.  Recommend a small USPS flat-rate box.  Please contact us for combined shipping.
