Bulgari Doppio Blue

For sale, my vintage Bvlgari ring. It's from years 1990.
The stones are pear-shaped rubellite and blue topaz. The ring is in yellow and white gold 18 carats with herringbone accents. The size is about 55,5, or UK O 1/2.
He weighs 17,22 grams.
Signed Bvlgari and 750. On the opposite side are two other features: what looks like a triangle and a number, perhaps 11.
The ring is delivered without box. I described it as an "acceptable" condition, because the two stones are striped. visible to the naked eye when looking closely. The price reflects this, but it's still a beautiful ring.
