This Black Tourmaline specimen features a compact, well-defined cluster of schorl crystals with strong vertical striations and a gemmy luster. The crystal faces are sharply formed, with subtle natural highlights along the ridges that emphasize the tourmaline’s prismatic structure.
Under ultraviolet light, a patch of hyalite opal activates dramatically, fluorescing a vivid neon green across the crystal surface. The hyalite occurs as thin coatings and small nodular deposits, creating a striking contrast against the dark tourmaline host. In natural light, the opal remains nearly invisible, making the UV transformation especially compelling for collectors.
This specimen comes from the Erongo Mountains, a locality celebrated for producing some of the world’s finest tourmaline–opal associations.
Dimensions: 2” x 1.75” x 1.5”
Weight: 124g
This piece is particularly appealing for collectors who appreciate clean, concentrated UV activity without overwhelming surface coverage. The hyalite fluorescence is bright and sharply defined, activating instantly under blacklight and shutting off just as quickly when the light is removed — a classic hallmark of quality hyalite opal.
Its compact size and strong crystal form make it ideal for UV cabinets, focused mineral displays, or as part of a curated Erongo suite.
Natural black tourmaline (schorl) from Namibia
Hyalite opal with intense green UV fluorescence
Sharp prismatic crystal form with strong striations
UV-reactive opal is subtle in daylight, vivid under blacklight
Famous Erongo Mountains locality
Black Tourmaline is commonly associated with grounding and protection, while hyalite opal is often linked to clarity and heightened perception. Together, they are thought to support energetic stability while enhancing awareness — particularly symbolic in specimens that reveal hidden beauty under ultraviolet light.
