During the latter part of the 19th century, garnet bracelets and brooches were particularly popular. Most familiar during the peak of popularity were varieties of pyrope. The hardness of garnets and their sharp fracture make them suitable as abrasives for wood, leather, glass, metals, and plastics. Garnet varieties have become known by misleading names, frequently consisting of a locality with the name of another mineral variety, such as Uralian emerald or Cape ruby.
The versatile garnet comes in a virtual rainbow of colors, including pink, red, purple, orange, yellow, violet, green, colorless, occasionally black, brown and many shades of red and green. The most common color of garnets is reddish brown. Garnets are a group of common silicate minerals that have similar crystal structures and chemical compositions.

Most natural garnets are mixtures of two or more of the following pure species: pyrope, almandine, spessartine, uvarovite, grossular, andradite. Garnets occur in a very wide variety of formations, colors, and clarities. Garnets were so called by the ancient Greeks since color reminded them of the pomegranate seed or granatum. The garnet is considered to be the birthstone for Capricornus (Goat): Dec. 22 - Jan. 19.
