Vintage opal stud earrings set in 9 CT gold with a rope or "florette" border.

Vintage opal stud earrings set in 9 CT gold with a distinctive rope or "florette" border. Key Features Gemstone: The iridescent, milky appearance with flashes of color (play-of-color) is characteristic of opals. Similar visual effects can also be found in moonstones or "aurora borealis" crystals, though the specific fire in these suggests opal. Setting: The stones are held in a filigree or crown-style setting, featuring a scalloped metal edge that surrounds the gemstone. Metal: The metal has a warm, yellow-gold tone common in Victorian or Art Nouveau inspired jewelry and are marked as 9 CT. 2.85 gram total weight, see photos. Style: These are stud earrings designed with a standard post and a butterfly back, consistent with mid-to-late 20th-century or modern "estate" style jewelry.  I'm open to reasonable offers and bundles, please take a peek in my closet.
