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. 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.
