Physical properties

Hardness: 7 (Quartz); Color: Neon yellow-green (artificial); Luster: Vitreous/glassy; Structure: Trigonal/hexagonal crystals; Cleavage: None

Formation & geological history

Natural quartz crystals formed over millions of years by hydrothermal activity in a geode cavity, subsequently chemically dyed to enhance color for decorative purposes.

Uses & applications

Home decor, beginner mineral collections, and decorative gifts.

Geological facts

Most neon-colored geodes found in souvenir shops are natural clear or white quartz that has been soaked in dye. If the color is too bright or concentrated in cracks, it is likely dyed.

Field identification & locations

Identify by the unnaturally uniform or neon color. Real sulfur is yellow but smells of eggs and is much softer. Often found in gift shops globally.
