Description

Tanzanite is found in only one location in the entire world — Tanzania, in Eastern Africa. Discovered in 1962, tanzanite is a relative newcomer to the gemstone market, yet it has grown incredibly popular among jewelers and collectors alike. This gem is strongly pleochroic, displaying different colors when viewed from different directions. Pure blue or violetish-blue hues are prized over bluish-purple hues. Tanzanite should be handled with care, as it is sensitive to temperature changes. Tanzanite is the birthstone of December.

Features

  • Strongly pleochroic — displays varying color from different viewing angles
  • Eye clean quality with a blue to violetish-blue color range
  • Heat treated for enhanced color
  • Available in a range of round faceted sizes from 1.5mm to 6mm
  • Sourced from Tanzania, the only known location in the world for tanzanite

Unfinished

Only one out of three stones was finished. The girdles on two were wide, extremely uneven, and not polished. Easy to see this even on 2mm stones. The one stone that was finished is excellent.
