Garnet Gemstone Beads and Charms from Rings & Things: Garnets come in a variety of shades, but generally when you hear the word "Garnet" you think of a deep rich red. Other colors of garnet usually include descriptive names. Garnets are named after punica granatum (pomegranate), due to garnet's resemblance to pomegranate seeds. Garnet is the most popular and well-known birthstone for January. We often have Kashgar, Hessonite and other colors of garnets but when we have garnets other than the standard red, they are likely to be limited availability -- so get them while you can!
