Green Tourmaline and diamond square Bombe style ring, 14kt yellow gold

smoke-free home. this is a 14 karat gold square Bombe style ring featuring one center round diamond set in four prongs with a prong set of Marquee Green tourmaline at each corner. a very unusual piece. appraisal attached and was $85. will include when shipped. it was appraised October of 2020 so probably gone up a little bit in value. Posh will also authenticate anything over $500 so please buy with confidence. they take 20% of sale price so please keep that in mind when purchasing. thanks! just thinning out my jewelry a bit. this is a rare piece. not sure you will see another one like it.
