HOWLITE FOR SALE

Howlite is a white, gray, and brown calcium-based mineral that forms as a result of evaporation. It occurs when calcium, boron, and silicon are readily available in an aqueous solution that begins to evaporate. As the solution dries up, the minerals come together to form crystals, similar to the formation of halite. It typically forms in botryoidal masses that resemble cauliflower or as nodules. Small, individual translucent howlite crystals have been encountered, but this type of formation is quite rare.
