Pair of vintage retailer sparkle glass vases

gorgeous set of black sparkle glass vases peacock bronze, deep blue (or violet), emerald green.
searching for an identification, no marks were found but one was listed on retailer ebay as "vintage Murano." In searching recently they have been described as "vintage Dale Tiffany Mardi Gras Favrile Art Glass Vase."
You decide. I just know they are beautiful and there are two.
