Large freeform shaped stone with a smoky-white parent material.
One face is carved into a curved shape revealing broad areas of rolling fire in green-gold, rich red, light green, and cobalt blue. The reverse face is almost flat with swirling fire in rich red, blue, and green.
This face has a few thin inclusions of soft ochre material, however they are not very noticeable.
There is much richer colour than captured in the picture.
And… it really does weigh over 10 grams.
