A highly aesthetic lab-grown bismuth crystal featuring perfectly terminated, stepped hopper formations with a brilliant metallic rainbow sheen. The iridescent colors range from deep purples and blues to golds and greens, subtly shifting as the specimen is rotated under light. This piece is self-standing and beautifully balanced, requiring no support for display. Its striking geometry and vivid coloration make it an eye-catching addition to any mineral collection or decorative space. While artificially grown, bismuth crystals like this are appreciated for their intricate structure, vivid colors, and metallic brilliance — a true fusion of science and art.
