PAVILION

CROWN

Addition # 10 - This is nice and the crown will appear to float. Note: The C2 depth can vary a bit, but I tend to like it like the diagram. You can see the "float" but it is not too deep. This is ideal in light to medium colors. The table can be left off on small stones. Cut in refractive indexes 1.62 to 2.14 with no changes.
