Deep red-orange core ringed by tight salmon and white concentric bands — that classic eye pattern Laguna is known for. The white chalcedony rind is thick and clean, cut is flat and even. At 24g this is a solid hand-piece for the price. 🔴

Black Tourmaline (Schorl) — one of the most geometrically striking varieties of the tourmaline group. Tourmaline itself is a complex boro-silicate, and schorl is its iron-rich end member: Na(Fe²⁺)₃Al₆(BO₃)₃Si₆O₁₈(OH)₄. The black crystals are prismatic, striated lengthwise, and often terminate in trigonal pyramids.

This Namibian specimen forms an X-shape — two crystals interpenetrating at an angle, a natural expression of the hexagonal crystal system’s threefold symmetry.

Why collectors love schorl:

• Piezoelectric and pyroelectric — it generates electric charge under pressure or temperature change

• Pegmatite-formed — grows slowly in boron-rich granite melts

• Universally associated with “grounding” energy in metaphysical circles

• Perfectly paired with smoky quartz and feldspar in raw matrix

Schorl is the most common tourmaline on Earth, but quality aesthetic clusters like this one — sharp, glossy, undamaged — are surprisingly rare.

Was debating whether or not to actually go agate hunting today because I was sure it'd be crowded and full of bugs but I'm very glad I went. Obsessed.
