Quartz with Red Uvite Tourmaline - Doubly Terminated Crystal on Druse Matrix, Brazil

A Brazilian Quartz association of unusual chromatic drama: a water-clear, doubly terminated Quartz crystal laid across a white crystalline Quartz matrix that is studded with lustrous, wine-red Uvite Tourmaline crystals. The combination of colourless transparency, chalk-white druse and saturated red is the whole argument for the piece, and it is a combination that Brazil produces only sporadically. The architecture is simple and effective. The principal Quartz crystal is a slender prism with a well-formed termination, resting diagonally along the matrix so that it reads as a single dominant line across the specimen rather than as one point in a cluster. Behind and beneath it, the matrix is itself a mass of small white Quartz crystals, sharply terminated and tightly packed, giving the back and flanks a crisp sugary texture. The red Tourmaline crystals are scattered across that white ground in loose constellations, individually small but numerous enough to govern the eye. Colour is where the specimen earns its keep. In ordinary reflected light the Tourmaline reads as a deep brick to garnet red, almost opaque at the thicker growths. Turn the piece toward a light source and the thinner crystals and edges open to a hot, transparent orange-red, with a few flakes flaring nearly amber. The main Quartz is colourless and glassy, carrying internal veils and a scatter of reddish and dusky inclusions along its growth planes, some of which appear to be included Tourmaline captured during growth. Against the opaque white matrix, that transparency is emphasised rather than lost. Lustre is vitreous and bright throughout. The Tourmaline faces are the most reflective elements, throwing small hard glints that shift sharply as the specimen is rotated, while the white druse returns a softer, more diffuse sparkle. Scattered flecks of brassy metallic sulphide add occasional golden points among the red. The white Quartz druse is not merely a support. It supplies the tonal contrast that makes the red legible, and its fine-grained crystal cover gives the back of the piece interest in its own right. A specimen of this format is best appreciated in the hand, where small changes of angle bring different Tourmaline crystals alight in sequence while the central prism stays luminous throughout.
