They were on necklaces and bracelets. But carnelian beads were worn exclusively by women.
Gemstones are identified by gemologists
Gemstones are identified by gemologists. The first characteristic a gemologist uses to identify a gemstone is its chemical composition. Gems are characterized in terms of refractive index, dispersion, specific gravity, hardness, cleavage, fracture, and luster. They may exhibit pleochroism or double refraction. Who describe gems and their characteristics using technical terminology specific to the field of gemology.
Next, many gems are crystals which are classified by their crystal system such as cubic or trigonal or monoclinic. They may have luminescence and a distinctive absorption spectrum. For example, diamonds are made of carbon (C) and rubies of aluminium oxide (Al2O3). Another term used is habit, the form the gem is usually found in. For example diamonds, which have a cubic crystal system, are often found as octahedrons.
Gemstone is desirable for its beauty
A gemstone is the naturally occurring crystalline form of a mineral. Gemstone is desirable for its beauty. It is valuable in rarity. A gemstone or gem also called a precious or semi-precious stone is a piece of attractive mineral, when cut and polished it is used to make jewellery or other adornments.

Gemstone is durable enough to be enjoyed for generations. However certain rocks, such as lapis-lazuli and organic materials are not minerals, but are still used for jewelry, and are therefore often considered to be gemstones as well. Most gemstones are hard, but some soft minerals are used in jewelry because of their luster or other physical properties that have aesthetic value. Rarity is another characteristic that lends value to a gemstone.
