Item Description

Dramatic and sculptural large intergrown cluster of jet-black schorl crystals from the famous Erongo Mountains. The impressive large dominating terminated crystal at the crest is 11.3 cm long and complete all-around! All of the crystal prism faces are striated, wavy or nubby, adding much character to the piece. Many of the crystals have spiky, rod-like terminations or are rod-like by themselves. Some people consider such spiky terminations and rods to be Foitite, a rare Tourmaline Group species discovered in 1993 (perhaps these are, but you need analysis to be sure). Specimens of this quality IN THIS SIZE are rare from the Erongo Mountains. 100 percent identification is only possible by suitable analytical methods but well-known dealer and Africa specialist, Charlie Key, told us that all such crystals are either foitite or a foitite/schorl series. The bit of contrasting white Feldspar is a nice complement. An unexpected BONUS is on the back at the attachment. An aesthetic cluster of partially oxide-coated to coated gemmy, hexagonal, goshenite (colorless) Aquamarine crystals, to 1.5 cm, is nicely situated. Ex Colin and Helen Owen Collection of South Africa. 1874 grams or 4.1 pounds. An exceptional large museum quality, rare and aesthetic example of the species with aquamarine. Valued at $3000-5000. From the personal collection of longtime Kalahari and Namibia dealers.
