Color Change Garnet is sometimes mistaken for alexandrite. A rare type of gem, the color change can be intense like in alexandrite from green to red. Lesser changes are from Yellow/browns to red and seen under fluorescent light and incandescent light. The strength of color-change will determine the value of the gem. Much sought-after by collectors and connoisseurs alike.
