Tourmaline

Tourmalines showing striking “neon” colours of blue, green-blue, green and violet first appeared in the trade in 1989 when a single deposit was unearthed in Paraíba State, Brazil.

Paraíba tourmaline is rare and incomparable to any other gem. Uncommon in sizes over 2 carats, the stones are always in high demand, attracting steep prices not seen with any other tourmaline variety.
In contrast to Paraíba tourmaline, other cool-hued varieties are more readily available and at far lower prices. These gems carry trade names such as ‘indicolite’, the name given to a range of blue tourmalines, and ‘verdelite’, the name given to a range of green tourmalines.
