CHARACTER AND SETTING IDEAS
Broad steps catch bright blue reflections as the stone turns, alternating with deep, darker areas. This is a geometric, reflective look rather than the scintillation of brilliant-style faceting. A simple setting could emphasize the outline, while a surrounding frame could make its pointed ends part of the design.

CLARITY AND SETTING GUIDANCE
The close-up photographs and movement video show the facet pattern and appearance at different angles. Please have your jeweler check the measurements and setting fit, including protection for the pointed ends, before making a mount.

PHOTOGRAPHS AND VIDEO
