These are vintage Swarovski rhinestones. They are in beautiful, almost royal emerald green color! Shape reminds me of kite. I don't have the right setting for them so I need to improvise.
These rhinestones are definitely old, with K. S & Co Edelweiss logo and two digit article code. The faceting is perfect and the gold foiling backing these stones mint! Just look at these perfect cuts! These look brand new!!!
