About the Diamond design

Across the top sit three openings, a squared trapezoid in the center with a slanted parallelogram leaning against each side, all cut off below by one long horizontal band of steel. Under that band the stone drops in two tall triangles split by a single vertical stroke, and those triangles stop well short of the bottom point, leaving a solid wedge at the tip. The crown takes barely a third of the height, leaving the long taper below to do the rest.
