This Black Tourmaline specimen features well-formed prismatic schorl crystals partially embedded in a light-colored matrix, creating a strong visual contrast between the deep black crystal faces and the pale host rock. The tourmaline crystals display crisp edges and smooth, reflective faces, giving the piece a bold, architectural presence in natural light.
Under ultraviolet light, an extensive coating of hyalite opal activates across the matrix and crystal surfaces, fluorescing an intense neon green. Unlike specimens where hyalite appears only in isolated patches, this piece shows broader surface coverage, producing a vivid, almost electric glow that dominates the specimen under UV while sharply outlining the tourmaline crystal geometry beneath.
This association is characteristic of material from the Erongo Mountains, a world-renowned locality for tourmaline and rare opal combinations.
Dimensions: 2.75” x 2” x 1.75”
Weight: 100g
This specimen is especially appealing for UV-focused collectors due to the strength and surface area of its hyalite fluorescence. The contrast between the opaque black tourmaline and the glowing opal matrix creates a high-impact visual effect that is immediately eye-catching under blacklight.
Its elongated form and mixed crystal–matrix presentation make it an excellent display piece, particularly for cabinets or shelves where both natural and UV lighting can be showcased.
Natural black tourmaline (schorl) from Namibia
Broad hyalite opal coating with intense green UV fluorescence
Strong contrast between dark tourmaline and light matrix
Well-defined prismatic crystal faces
Famous Erongo Mountains Locality
Black Tourmaline is commonly associated with grounding and protection, while hyalite opal is often linked to clarity, heightened awareness, and illumination of subtle energy. Together, they are thought to support energetic balance while revealing hidden layers — mirroring the specimen’s dramatic UV response.
