Lalaounis 22K Mesopotamia Ring

I simply HAD to buy this gorgeous ring I found while sourcing in Paris! Not only is Lalaounis one of my favorite designers, but this bypass style is both chic and comfortable. I adore the textured finish. It fits about a 7.5, and I would not recommend sizing this one. It weighs 13.1 grams. This is circa 1980 and is part of their Mesopotamia collection. I've searched online, and the only one I found sold for much more than I'm asking.
