Platinum and 18k Yellow Gold Ruby and Diamond Ring

We just upcycled this vintage 199's mounting. The quality and condition is perfect other than the dated marquise head it originally had. We removed it and added the 18k yellow gold bezel with this old Ruby. The color of this Ruby gives off a purplish red color that resembles a Garnet.
