Brandberg Crystals and the fascinating 'moving bubble' phenomenon
Brandberg crystals from the Gobobos diggings in the shadow of the great Brandberg Mountain in Damaraland, Namibia, are widely known as being some of the finest Quartz crystals in the world. They have a range of amazing and unusual features including their super-shiny vitreous luster, which gives them an almost polished look, although they are 100% natural and straight from the African earth! Some are water-clear while others have amazing phantoms (areas of color within the crystal which often follow the contours of the point) either of amethyst (purple) or of a smoky color. Still others have bright red or metallic flecks within the crystal, made up of Hematite or Lepidocrocite, both forms of iron oxide.
Another amazing feature is the Enhydro crystal with tiny moving bubbles that slide and dance about in little water-filled chambers within the crystal. Enhydro means: ‘water within’. Numbers of theories have been advanced by Geologists to explain the source of the these fascinating moving bubbles. Here is one of our favorites: crystallization occurs from a slow cooling process of the mineral Quartz solution after volcanic activity. When, as the result of a freak occurrence, this cooling process is greatly accelerated, a small amount of water is sometimes trapped within the crystal as it solidifies. Sometimes a little air is trapped within this water, resulting in the formation of a moving bubble inside a water-filled cavity within the crystal. When the crystal is rotated, or gently moved from side to side, the bubble moves! This amazing, almost unbelievable sight is endlessly fascinating and intriguing to watch!
Some crystals are ‘floaters’, which means that they are completely formed, whole crystals, without any attached matrix or rocky material.
For these, and many more reasons, Brandberg crystals have become famous and highly sought after by enthusiasts and collectors the world over.
