Grossular is the garnet mineral that shows the widest range of colors. As pure calcium aluminum silicate it is colorless, but impurities can tint it shades of pink, orange (hessonite), yellow, brown and green (tsavorite). This group of 39 grossular garnets, averaging about 0.50 carat each, range in color from light orange to colorless to medium dark green. These gems were found in Kenya along the border with Tanzania.
