Bismuth Crystal Specimen 2.25" - Iridescent Metal Display Piece

Iridescent bismuth metal specimen for science decor, collection, or display.

Measures approximately 2.25" Height x 1.50" Length x 2" Width.

Material: Lab-grown bismuth metal crystal - Element #83 on the periodic table.

Bismuth is a naturally occurring brittle metal. This specimen was grown in a lab to form the colorful geometric hopper crystals. No dyes - the rainbow colors come from a thin oxide layer on the surface. Handle gently as the edges can be sharp.
