Platinum and 18k Yellow Gold Rubellite Tourmaline and Diamond Ring

We just upcycled this vintage 1990s 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 Rubellite Tourmaline. The color of this Rubellite gives off a purplish-red color.
