Unveiling the Complexities of Stibnite

In the annals of history, the mineral stibnite (antimony sulfide, Sb₂S₃) has played a significant role, particularly in ancient Egypt where it was a key ingredient in kohl, a traditional eye cosmetic. This use dates back to the protodynastic period of Egypt, making it one of the earliest known cosmetic applications of a mineral substance.

Beyond its role as an eyeshadow or eyeliner, stibnite was also attributed medicinal properties. Ancient texts, including those by Pliny the Elder in the 1st century CE, describe multiple medicinal remedies involving antimony sulfide. The use of kohl containing stibnite was believed not only to enhance beauty but also to protect the eyes from infections, ward off evil spirits, and possibly provide therapeutic benefits.

Culturally, these traditional eyeliners—known by various names such as kohl, kajal, and surma—have been used widely across Africa, South Asia, and the Middle East. They continue to be used today in some communities for both decorative and perceived medicinal purposes, including to protect children's eyes and ward off the "evil eye."

However, it is essential to note that stibnite (and compounds containing antimony) can be toxic, and modern awareness emphasizes caution in its use as cosmetic eye makeup due to potential health risks.

The most spectacular stibnite specimen known today is displayed at the American Museum of Natural History. It has a metallic lustre, reflecting light perfectly like a mirror, and usually forms in hydrothermal deposits. Stibnite has one perfect cleavage direction and a hardness of only 2 on the Mohs scale, making it extremely soft and brittle.

Dark, slender, needle-like prismatic stibnite crystals are prized as inclusions in rock crystal quartz and calcite. Stibnite is lead-grey with a blue tint and can show some iridescence. The specific gravity of stibnite is 4.63, and it is a natural mineral source of the chemical element antimony (Sb).

Stibnite is rarely fashioned or used in jewellery due to its fragility and brittleness. It forms as orthorhombic crystals that can be heavily striated along the prism's length. Well-formed crystals of stibnite are usually found in intricate clusters of radiating crystals or nest-like formations.

The largest known deposits of stibnite are in China (Xikuangshan mine), as well as in Russia, USA, Japan, France, and Germany. The Greek word stimmis became 'stibium' in Latin. Dioscorides, the Roman naturalist, referred to stibnite as πλατυόφθαλμον (platyophtalmon) or στίμμις (stimmis).

In 1832, the mineralogist François Sulpice Beudant named the mineral stibnite. The dual role of stibnite-based kohl as both a cosmetic and a medicinal product illustrates its importance in ancient and traditional healthcare and cultural practices.
