Bismuth Crystal (Lab Grown)– Iridescent Hopper Crystal
Dimensions: 4.4 x 3.5 x 2.7 cm

A dramatic lab-grown bismuth crystal specimen featuring exceptionally pronounced hopper growth and deeply stepped geometric architecture. Layer upon layer of angular bismuth creates an almost architectural formation, with large terraced faces surrounded by smaller square and rectangular hopper crystals.

The highly reflective metallic surface displays iridescent shades of gold, silver, pink, violet, green, and blue, with the colors shifting as the specimen is viewed from different angles. Particularly striking are the deep recessed crystal faces, where the repeated stair-step growth is especially easy to see.

Bismuth is a naturally occurring metallic element. These distinctive crystals are produced by melting bismuth and allowing it to cool and crystallize. A thin oxide layer that develops on the surface during cooling produces the characteristic rainbow iridescence.

Disclosure: This bismuth crystal is human-grown (lab-grown) from bismuth metal and is not a naturally formed mineral specimen. Its distinctive geometric “hopper” crystal structure develops as molten bismuth cools and crystallizes. The iridescent surface colors are produced by a thin oxide layer that forms on the bismuth during cooling.
