Quartz Var. Amethyst — Buck Mtn, Oregon

This enchanting amethyst cluster from Buck Mountain, Oregon is a masterclass in subtle beauty. The main crystal rises with excellent hexagonal form, displaying soft lavender-to-violet coloration that concentrates near the termination and deepens in zones through the body of the crystal. Surrounding it is a constellation of secondary crystals — some clear, some touched with pale purple — that fan outward in a natural, organic arrangement. Several faces catch the light with brilliant iridescence, flashing blue, gold, and rainbow hues across the facets. Inclusions of golden and dark metallic minerals (likely iron oxides or small mica flakes) are visible inside the crystal body, adding depth and natural character. The base of the specimen is textured with smaller companion crystals and matrix material, grounding the whole piece beautifully. Buck Mountain in Oregon is known for producing amethyst quartz in hydrothermal vein systems associated with volcanic and metamorphic terrains. The pale, pastel coloration typical of Pacific Northwest amethyst — rather than the deep purple of African or Brazilian material — is a regional signature caused by lower concentrations of iron and natural irradiation during crystal growth. The iridescent surface effects, often called 'iris quartz,' result from microscopic fractures or twinning planes within the crystal that diffract light like a prism. The presence of metallic inclusions suggests this crystal grew in a minerally rich hydrothermal environment, perhaps with pyrite or mica nearby. This style of amethyst has a quiet, ethereal quality that collectors prize for its Pacific character. This specimen comes from the C.W.B. Minerals collection, as noted on the labeled placard, and has been carefully curated as part of Brian's traded and collected mineral holdings at Iron Mountain Ranch in the Tunk Valley. It's the kind of piece that rewards close inspection — the more you look, the more it gives back.
