About this specimen
A single black tourmaline blade lies across the top of a cream feldspar crystal, glossy where the light rakes it and striated along its whole length like the shaft of a file. At one end a smaller glassy crystal, colourless and faintly clouded, has grown hard against it. The feldspar underneath is half the appeal: a blocky crystal with a broad stepped cleavage face, cream turning to rust-orange where iron has stained the surface, freckled with tiny dark tourmaline chips.
Both minerals came out of a pegmatite pocket, the blade settled along a feldspar face rather than buried in it. The striations running parallel to the tourmaline’s long axis are the group’s signature, and at Mohs 7–7.5 that blade will outlast everything near it; the feldspar, softer and readily cleaved, is the part worth protecting on the shelf.
5.6 × 3.3 × 4.3 cm, 140 g. Shown in hand so the scale is plain, with the acrylic block below only steadying it for the camera. This is the specimen you receive.
