The word tourmaline, originally from Sinhalese, means a gemstone that combines different colours. Tourmaline is widely regarded as one of the five leading gems.
Origins: Brazil and the United States are the main sources, followed by China, Sri Lanka, and Africa.
Exhibit Introduction: Green tourmaline and rock crystal form together symbiotically, displaying the most pristine status in the formation of precious stones. It is extremely difficult to find a high-quality stone, which may require an extensive search through tons of ore. As such, the value of tourmaline continues to increase.
