I attempt to accurately represent and describe cut stones and rough
as to appearance, size, origin and fully disclose any known
treatments in its description. Because you view the images on a
different monitor with different settings, color is particularly fickle
to represent, but I do my best.

designed for a large piece of aquamarine.  This design is not especially difficult to cut, but the pavilion can be trying at times.
