These cufflink buttons are made of solid sterling silver and natural gemstone. The elegant design in blue and green 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: 20x14 mm (0.79x0.55") in diameter. This original jewel is handmade by me. You will receive the cufflinks from the photo. They come packed in a box.
