Developed by self-taught gem carver and visionary jewelry artist Glenn Lehrer, the TorusRing™ cut explodes the familiar model of the ‘expected’ gem cut. Drawn from “the most prevalent form in nature,” the TorusRing reflects the torus—and just what is a ‘torus’? Well, picture in your mind’s eye the center of a hurricane as viewed from outer space, or a galaxy as viewed from the Hubble telescope, or the water in a whirlpool, or even the brilliant iris of your own eye. Each TorusRing™ gemstone is hand-cut and hand-faceted to draw light from without the stone and capture it within, endlessly multiplying, flowing from curved facet to curved facet. Says Glenn, “I carve in light . . . bending light . . . turning each sparkling ray into an almost liquid medium.” A TorusRing cut takes about five times longer to create than a traditional round brilliant and features not only the ‘eye’ at its center, with a 1.3mm white diamond (SI clarity; H/I color) bezel-set in gold, but also a negative (inverted), faceted cone painstakingly carved into the back of the stone, behind the eye. The torus effect of the finished stone is hypnotic, heart-stopping and utterly heavenly.
