What type of tourmalines are most commonly found in the gem market?

Elbaite is indeed the most commonly found type of tourmaline in the gem market. This variety encompasses a range of colors and is well-known for its stunning vibrancy and ability to exhibit a variety of hues within a single crystal. Elbaite serves as the main tourmaline species from which many gemstones are cut, contributing significantly to its prevalence in the jewelry market. Its occurrence in a wide spectrum of colors, such as green, blue, pink, and colorless, makes it particularly popular among gem enthusiasts and jewelers.

While other types of tourmaline like rubellite (which refers specifically to red elbaite), watermelon (which features both green and pink colors within the same stone), and Paraiba (known for its neon blue and green colors) are highly regarded and sometimes command higher prices, they are less commonly available compared to elbaite. Each of these varieties is valued for unique characteristics, but the extensive range and accessibility of elbaite make it the most commonly found type in the market.
