Is a heat treated Pariba Tourmaline still valuable?

Question

I mean Paraiba

Answer 1

The short answer is yes. Heat treatment will enhance the color and may make the stone more brittle. You should fully understand what you are buying with Tourmaline as there are many varieties and prices. Heat treatment is common but good looking stones without enhancement should command the best prices although treated ones are still just about the same price. Know your source before buying.
