The 1 1/8 inch diameter laser etched shell buttons come from a shop in Paris. Th striking black and white laser etched design has a matte finish. The earring wires are handmade sterling silver, stamped “925”, designed by my Australian friend Sonia Collard. Almost any sew-through buttons will fit on these wires as long as they are smaller than about 1 1/4”. That means a big earring wardrobe for us button collectors!
