This article aims to discuss the properties, origin, history, and uses of Chrysoberyl gemstone and jewelry.

Properties of Chrysoberyl Gemstone: 

Chrysoberyl is a beryllium aluminum oxide mineral with a chemical formula (BeAl2O4). It has a hardness of 8.5 on the Mohs scale, which makes it a durable and hard-wearing gemstone. Chrysoberyl has an adamantine luster that makes it extremely reflective and shiny. The mineral is transparent to translucent, depending on the specific type.

Moreover, Chrysoberyl exhibits pleochroism, which refers to its color-changing property in different lighting conditions. For instance, the gemstone appears greenish-yellow in daylight, while under artificial light, it appears reddish-brown. This unique property makes Chrysoberyl a highly sought-after gemstone for jewelry.

Chrysoberyl's crystal system is orthorhombic, which means it doesn't form in perfect symmetrical shapes. The gemstone is typically 9-10% beryllium and 89-90% aluminum, with trace amounts of chromium, iron, and titanium that give it its distinctive colors. The green Chrysoberyl gemstones get their color from the presence of iron and chromium, while yellow and brown Chrysoberyls get their color from iron and titanium.
