Lot includes five quartz crystal specimens. Crystals are individual. 1) large prismatic crystal (approx. 3.5x1.75x1.5"), rhombohedral, very large x-face (1), crystal at top transitioning to milky at base, iron staining, minor sprouting on one facet; 2) large (3.25x1.5x1.25") prismatic crystal, rhombohedral, light citrine appearance despite very minor iron staining, iridescence patches, milky at base, few daughter crystals and sprouts, has 4-facet negative imprint with what appears to be Tessin habit (steep rhombohedral faces alternating with m-faces, showing shiny surfaces instead of striations. 3) beautiful prismatic crystal intergrowth cluster tabular crystals (approx. 2.75x1.75x1.5"), very minor iron staining but shows slightly citrine appearance, chip at top facets, daughter crystals forming show rhombohedral habit! This is a unique example of multiple crystal habits in one specimen; 4) beautiful prismatic crystal cluster (approx. 2.5x2x1.75"), very minor iron staining, chip at top facet, larger crystals display rhombohedral habit with crystal sprout displaying Dauphine habit, with some iridescence patches. This is a unique example of multiple crystal habits in one specimen; 5) very large prismatic crystal cluster (7.75x4.75x3.25") on host rock, displaying both trigonal and Dauphine habits, with clear, slight citrine appearance to crystals, slight iron staining, milky at base, split and intergrowth crystals sprouts, nearly radial, with few iridescence patches. This is an excellent specimen needle growth ('needle' quartz is grown quickly at relatively low temperatures, with quick growth caused by quickly falling temperatures and/or pressures, indicating a tectonically active environment or rising brines that cooled quickly. Natural growth lines evident on all facets. Chunlin Collection.
