Secure and accent your cuffs with these cufflinks, handmade from sand gathered from your choice of one of thousands of picturesque world beaches. Jewelrymaker Holly Daniels Christensen sets a pinch of sand from your favorite seaside spot in silver bezels sealed with resin. Organic and utterly modern, they're a unique sculptural way to add a tangible reminder of a laid-back, sunny day at the beach to an occasion that's more buttoned-down. Handmade in Massachusetts, the cufflinks come with a card that indicates the source of the sand.
