Art Deco Platinum Diamond 1.58ct Ring with GIA certificate

Art Deco Platinum Diamond 1.58ct Ring with GIA certificate~This is an early Art Deco diamond engagement ring, circa 1920-25. The center is an Old European cut weighing 1.58ct with a GIA certificate stating G color and VS2 clarity. The diamond is so white, it's almost blinding. It's a gorgeous diamond, my favorite cut, a small table and small culet. The center diamond is by single cut diamond, going down the shank and in the square box of the mount. Ring size is 7 1/2, can be sized.
