Tourmaline and opal, October’s birthstones and eighth wedding anniversary

The initial confusion of the Tourmaline stone’s identity is reflected in its name which derives from Sinhalese, the language of Sri Lanka Toramalli which means ‘mixed gems.’ It is also the gemstone that represents the eighth wedding anniversary.

Why we are in love with Tourmaline?

  1. Trigonal System: Tourmaline crystalizes in the trigonal system; no other common mineral has three sided prisms.

  2. Watermelon Variety: Watermelon Tourmaline is green on the outside and has a delicious pink colour on the inside.
