Personal Note From Natural Gems Belgium:

This oval shaped cabochon has very good polish grade, good symmetry, and has a nice natural variation of orangy red, deep orangy red and greyish grey as well as orangy white color tones in straight and curved lines. Very nice pattern, very good distict color
