Abstract

A gemstone is a physical material that has intrinsic value and possesses fundamental qualities such as beauty, durability and rarity. Gemstone identification might seem like a niche skill, relegated to the world of gemologists and jewelers. However, understanding how to identify gemstones is far more relevant than one might think. Identifying gemstones helps to protect one against fraudulent purchases to appreciating the natural beauty of the Earth's treasures. The ability to distinguish between genuine and synthetic stones, or even identify different varieties of the same gemstone, adds depth to our understanding of materials and enhances our critical thinking skills. To scientifically identify different precious stones found around Zagga Bali Local Government of Taraba State, the physical properties such as specific gravity, cleavage, hardness, durability or toughness, twinning, crystal habit, crystal system and colour were used in analyzing selected special stones. The results were compared to other precious stones found in the literature. This research work verified and authenticated the presence of the ten (10) special stones within Bali Local Government of Taraba State. These gemstones are rich in Lithium which could be used in the production of batteries and even applied in optical technology.
