I was born in May. As the birthstone for May, the emerald, a symbol of rebirth, is believed to grant the owner foresight, good fortune, and youth. Emerald, derived from the word smaragdus, meaning green in Greek, was mined in Egypt as early as 330 B.C. Today, most of the world’s emeralds are mined in Colombia, Brazil, Afghanistan, and Zambia.

Amethyst is the birthstone for February! That's my stone. Amethyst is a purple color gemstone.Amethyst ranges in color from pale lilac to deep purple. Its color is as unique as it is seductive, though in fact this gemstone of all gemstones is said to protect its wearer against seduction.

Garnet is a group of minerals that have been used since the Bronze Age as gemstones and abrasives. Today, it is widely known as the birthstone for January.[1] Garnets are most often seen in red, but are available in a wide variety of colors spanning the entire spectrum. The name "garnet" comes from the Latin granatus ("grain"), possibly a reference to the malum granatum ("pomegranate"), a plant with red seeds similar in shape, size, and color to some garnet crystals.
Six common varieties of garnet are recognized based on their chemical composition. They are pyrope, almandine, spessartite, grossular (varieties of which are hessonite or cinnamon-stone and tsavorite), uvarovite and andradite. The garnets make up two solid solution series; 1. pyrope-almandine-spessarite and 2. uvarovite-grossular-andradite.
