Stibnite is a classic mineral species with fine crystal clusters and long curved crystals being the pride of many collectors. The slender curved metallic blades of stibnite can resemble Arabian swords. The curving of the long bladed crystals is due to twinning where one twin plane bends the crystal one direction and another twin plane bends it in the other direction. This can occur numerous times down the length of one crystal.
