Personal Note From Natural Gems Belgium:

This oval shaped cabochon has good polish grade, very good symmetry, and has a nice natural variation of centered deep Brownish red and grey to orangy silk surrounding the brownish red. Very nice pattern, very good specific color make it a unique agate cabochon
