Artisan Made Silver Tone Earrings with Amber Type Stone

Gypsy style artisan made earrings featuring filigree metalwork, a silver loop around a central amber-coloured stone and a silver tone leaf drop at the bottom. The stone has a milky white colour running through it creating an interesting design and the silver tone wire wraps around the sides to secure the stone. The fishook fitting is also silver-toned. This is artisan made as I purchased it about 15 years ago from the vendor selling her handmade jewellery in New Orleans. There is a matching bracelet in my closet as well. These earrings looks like sterling silver, but I cannot find any stamps or marks on it to indicate so. Therefore, I assume it is simply a silver-tone costume jewellery in excellent condition with no wear. I cannot recall what she said it was made of. Material - unknown silver-tone metal, stone - unknown Measurements. Length of earring, not including fishhook or leaf drop at bottom is 4 cm - add 1.3 cm for leaf drop.
