Palm-sized, with a defined eye socket, fenestra, and upper and lower tooth rows carved into the stone.\u003c\/p\u003e\n\u003cp\u003eIn daylight the piece reads as weathered bone. The matrix is gray and black speckled with rust-red iron staining running through it, and the pattern differs on every skull.\u003c\/p\u003e\n\u003cp\u003eUnder 365nm UV light, the sodalite inside the stone fluoresces bright orange. The glow follows the natural mineral veining rather than the carved detail, so the lit pattern is unique to each piece.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAbout the stone\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis is a new one for the store! Syenite is a coarse-grained igneous rock formed as magma cooled slowly underground. It resembles granite but contains little to no quartz, built instead from alkali feldspar with darker hornblende and biotite scattered through it. When sodalite is present in the matrix, the rock fluoresces orange under longwave UV. This material is also known in the collector market as Yooperlite.\u003c\/p\u003e\n\u003cp\u003eThe fluorescence comes from the mineral itself, not from a coating or treatment, and it does not fade with handling or time.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetails\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMaterial: fluorescent sodalite syenite, source unverified\u003c\/li\u003e\n\u003cli\u003eApproximate size: fits in the palm of the hand\u003c\/li\u003e\n\u003cli\u003eFluoresces orange under 365nm longwave UV\u003c\/li\u003e\n\u003cli\u003eHand-carved from natural stone\u003c\/li\u003e\n\u003cli\u003eOne piece, selected from current stock unless otherwise noted\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eNotes\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eBest viewed with a 365nm UV flashlight in a dark room. 395nm lights and standard blacklight bulbs produce a much weaker response.\u003c\/p\u003e\n\u003cp\u003eColor, glow density, and matrix pattern vary between pieces.
