A Jour
a·jour | ä-ˈzhu̇r
adjective
An open setting that leaves the pavilion facets open to the light
Punctured, cut away, or made colorless to such a degree to form a design, keeping the back of the stone open. This space allows additional light to pass into the gem so its shine and color appear more effervescent. In the 1800’s, a jour settings in fine jewelry gemstones quickly gained popularity, leading to its vast audience today. In effect, it is a scaled-down version of stained-glass and is deemed very laborious.
