Natural Amethyst Appraisal

Aura Amethyst Geode/Cluster

This stunning piece is an Amethyst Geode or Cluster with an apparent aura coating, exhibiting a captivating play of iridescent colors. The specimen features a raw, irregular shape, consistent with natural crystal formations extracted from a geode. Its physical characteristics include numerous pointed crystal terminations of varying sizes, densely packed on one side of a larger, lighter-colored matrix. The primary color of the crystals ranges from a delicate, pale lavender to a richer purple, typical of amethyst. However, the most striking feature is the vibrant metallic sheen across the crystal faces, displaying Hues of electric blue, fuchsia, gold, and green. This iridescence suggests an 'aura' treatment, where the amethyst has been bonded with metallic vapors (like titanium or niobium) under high heat, creating a thin, permanent layer on the surface that diffracts light. The underlying matrix appears to be a lighter quartz or possibly the outer crust of the geode, varying from an opaque white to a translucent, grayish-purple. The reverse side of the specimen, partially visible, appears rough and unpolished, consistent with the natural rock from which the crystals grew, showing some dark gray or black inclusions or rock material. There are no visible signs of significant damage such as large chips or cracks, and the crystal points generally appear intact. The craftsmanship lies in the natural formation of the crystals and the applied aura treatment, which offers a uniform and vibrant coating. The estimated age of the mineral formation itself is millions of years, while the aura treatment would have been applied recently, likely within the last few decades, as a modern enhancement technique. This piece exemplifies a high-quality display specimen due to its vivid coloring, well-formed crystal points, and the eye-catching aesthetic provided by the aura treatment. No specific maker's marks or signatures are discernible, which is typical for natural mineral specimens.
