The Emerald Abyss 1-5/8"

The Object A masterclass in optical depth, this signature Vortex marble by Kevin O'Grady pulls the viewer into a spiraling singularity of light and color.

The interior structure resembles shimmering dragon scales that shift from deep ocean teal to emerald green depending on the angle of light. The "Vortex" technique—pioneered by O'Grady himself—creates an illusion of infinite depth, making the sphere appear far larger on the inside than the outside.

This is not merely glass; it is a portal. The termination of the vortex creates a perfect "black hole" effect at the base, anchoring the chaotic brilliance of the walls in absolute silence.

The Artist Kevin O'Grady (Roswell, NM) is widely recognized as the "Father of the Vortex." Since 1993, he has been one of the most influential figures in the American borosilicate movement. His work is held in major museum collections and is prized for its clean optical termination and heavy use of precious metals.
