Comments:
Sometimes chrome kornerupine comes in a lovely light, earthy, pastel version of green and purple. These gems tend to be very bright, with low-key mixing of colors to form gray, purple, green, and some light blue tones.
While these gems are not quite as vivid as the strongly colored ones, the trichroism is still readily on display.
