This captivating specimen features blue kyanite crystals embedded in schist, some of which are accompanied by garnet. The kyanite crystals originate from the Karoi deposits in Zimbabwe. Let’s delve into the details:

• General Description:

  • Kyanite is an aluminosilicate mineral, typically found in aluminium-rich metamorphic pegmatites and sedimentary rock.
  • In metamorphic rocks, the presence of kyanite often indicates high pressures exceeding four kilobars.
  • These crystals were sourced from fissures in the Karoi deposits, often filled with black mica.
  • Most of the crystals are small to medium-sized, with less than 5% yielding larger, specimen-grade crystals.
  • Kyanite is highly sought after for jewellery making and in alternative markets.

• Zimbabwean Kyanite:

  • The kyanite from Zimbabwe boasts a rich blue colour, although the gemmy clarity varies.
  • Other colours, such as black, green, and orange, have been reported in kyanite crystals worldwide.
