Neon Green Fluorescent Hyalite Opal on Black Tourmaline - Height: 4.3 cm - Width: 3.2 cm- 46 g

Hyalite opal is a form of opal known for its distinctive glassy, transparent to translucent appearance. When fluorescent, as in this neon green example, it exhibits a captivating glow under ultraviolet light, which highlights its unique internal structure. This specimen is notable for being found on a matrix of black tourmaline, a mineral known for its rich black color and striated texture. The contrast between the vivid green hyalite opal and the dark tourmaline base creates an attractive mineral specimen for collectors and enthusiasts of fluorescent minerals. Minerals like hyalite opal form in volcanic environments and their fluorescence is due to trace elements or structural features at the microscopic level.
