SQ Corundum

SQ represents square cut corundum, a classic cut with 90-degree corners. The stones have rows of trapezoidal and triangular facets beautifully arranged in symmetry. Light moves across these mirror-like planes producing exquisite brilliance. Square cuts like the emerald have graced fine jewelry for over a century thanks to their timeless appeal. The straight lines and geometric shape frame corundum elegantly. Square cuts make ideal solitaire engagement rings, with table dimensions tailored to each stone. For corundum’s remarkable hardness and clarity, the square cut is a perfect match.
