Inderite and Ulexite. R. Currier collection. The scale at the bottom of the image is an inch with a rule at one cm. When the Inderite crystals were found at Boron, they were white/transparent. After a few years in the air of the Los Angeles basin, they turn white on their surface. The white mineral can be removed by soaking them in water for a few minutes.
