A Gemstone Spectrum
In the gem and mineral world, the word tourmaline is synonymous with color. Tourmaline is found in almost every imageable hue from ruby-red to emerald-green to electric blue. Amazingly, two or more intense and highly contrasting colors can even be found in the same stone making tourmaline a spectacular display specimen and gemstone.
Tourmaline has been cherished in Europe´s royal treasuries for centuries but until relatively recently was assumed to be ruby or zirkon.
