Color Change Garnets are very unique stones. The color
change in seen when viewing the stone in incandescent
light comparted to daylight or florescent light. While
every garnet does display some color change, these are
pronounced. I basically have 2 types, the first change
from a redish to bluish color, and the others go from a
pink bronze to golden brown. The hardness of garnets is
7 to 7.5, and Garnet is the birthstone for January.
