ABOUT: I love this ornate Victorian setting.  The prongs look like the top of a crown and there are ball rivet details at each shoulder.  Nice sized piece leading up to a very blue glowing opal.   Stamped 18k twice inside.  Please note the measurements as I have small fingers and it can be difficult to determine scale from pictures. Antique box is not included. MEASUREMENTS: Ring is currently about a size 8 1/4.  The ring face is 16.5mm north south.  The opal is about 14x10mm and the piece stand Oval Cabochon Opal Ring Fine Jewelry, Fine Jewelry Oval Cabochon Opal Ring, Oval Cabochon Opal Ring In Fine Jewelry, Luxury Oval Opal Ring With 17 Jewels, Classic Oval Cabochon Jewelry For Formal Occasions, Classic Yellow Gold Oval Cabochon Jewelry, Heirloom Gold Opal Cabochon Ring, Heirloom Gold Opal Ring With Cabochon, Formal Oval Cabochon Opal Ring
