Gemstones

A gemstone is a naturally occurring crystalline form of a mineral, valued for its rarity and beauty and durable enough to be passed down from generation to generation. Often referred to as precious or semi-precious stones is cut and polished to make jewelry or other embellishments. Some rocks, lapis-lazuli for instance and some organic materials, amber for example are also considered gemstones. Rarity and lustre are often used to determine the value of the gemstone.

Gemologists, who study gemstones, identify them by chemical composition. Diamonds are made of carbon (C) and rubies are made of aluminium oxide (Al2O3). They are also identified by crystal system or shape: cubic, trigonal or monoclinic. Habit or the nature in which they are found is gemstone identification characteristic. Other classification and identification characteristics include: group, species and varieties, dispersion, specific gravity, hardness, cleavage, fracture and lustre as well as refractive index.

Since gemstones are considered very valuable and are sought after by many people, they are often written about extensively in blogs such as the Diamond Blog.

Diamonds remain one of the most coveted of the gemstones. Precious gemstones would include tanzanite, diamond, ruby, sapphire and emerald, and are often found in many types of rings including engagement and wedding rings. An inclusion or flaw is inherit in some stones; emeralds for instance.
