Victorian garnet bracelets

Garnets are very beautiful by nice deep colors. That's why I love garnets. As you know there are different garnets and in various colors between pink red till deep red/brown. Here I show you two of my garnet bracelets. The first one is Victorian with a rose gold clasp. This clasp is decorated with little garnets and pearls. The second bracelet is of old garnet beads with a modern yellow 14 k gold clasp. As you can see on my other garnet jewelry. I showed you already a garnet necklace and pendant. These garnet beads have a more deep red/brown color .

Recently placed on this side. Also my garnet ring has deep colored garnet http://www.collectorsweekly.com/stories/38260-garnet-and-pearl-18ct-gold-ring.
Perhaps there is somebody who can tell me more about the origin and difference in colors of garnets?
