These cufflink buttons are made of solid sterling silver and natural gemstone. The elegant design in grey with green yellowish reflections colour is an ideal accessory to wear with a French shirt. I would recommend them for occasions such as a wedding, a business meeting, a party or simply as a gift for a special person. The upper part with the stone has the size: 16x16x5 mm (0.63x0.63x0.2"). This original jewel is handmade. You will receive the item as pictured
