Hessonite

Description

A golden brown to red color gemstone composed of grossular (calcium aluminum garnet) which has a small portion of iron. Hessonite resembles yellow zircon in color and both were called hyacinth in ancient times because they were found in the same gem-bearing gravels of Ceylon. Hessonite is softer than quartz and less brittle than zircon and hence, was used in ancient engraved gems (Ogden 1982).
