Sleepers composed of natural shell heshis and gold-plated spacers For information, all primers are made of brass without nickel or lead and are plated in France. The gold-colored metal is gilded with 24-carat fine gold above 1 micron. All my jewelry is designed and assembled by me in my workshop in the heart of my shop. Each model is unique but I can offer you a new model with the same pearls but worked differently.
