Physical properties
Mohs hardness 3.5–4.5; light green artificial dye with brownish veining; dull to porcelain-like luster; fine crystalline/massive structure.
Formation & geological history
Formed via alteration of magnesium-rich rocks or sedimentary borate deposits, subsequently carved, drilled, and dyed artificially.
Uses & applications
Commonly used in fashion jewelry, bead crafting, ornamental carvings, and as an affordable imitation of turquoise or gaspeite.
Geological facts
Naturally white and porous, magnesite and howlite absorb dyes exceptionally well, making them popular worldwide for cheap decorative carvings.
Field identification & locations
Identified by low hardness, lack of natural gemstone luster, and dye pooling in the engraved grooves or matrix cracks.
