Composed of silver, lacquer and reverse painted and engraved crystal, this exceptional ring was a collaboration of two French modernist artists, Despr??s and Cornault. The ring centers a glass crystal prism above a polychrome abstract-design painting in miniature by Cornault, mounted by Despr??s within a silver and black lacquer surround, flanked by stepped and incised chevron form shoulders with subtle dark patination. Uniting an intriguing abstract painting with the geometry of interlocking planes and layered strata, this rare ring is powerful work of painterly and sculptural modernism.
