Garnets

The garnets are an unexpected habitat for microbes because of their hardness.

Garnets were used as beads in ancient Egypt.

Garnets vary considerably in chemical composition, but the variation is limited within a certain range.

The garnets in the detritus are accompanied by zircon, spinel, corundum, cyanite, tourmaline, olivine, etc.

I like how the violets and garnets combine with the yellows, oranges and lime greens.
