This coaster is the first design their company ever created. It has become a signature design for the company, and an embodiment of everyday luxury. Hand-sculpted from agate gemstone which formed inside ancient lava streams, and painstakingly matched into sets of 4. Beloved as gifts for hostesses, hosts, brides, and grooms-to-be. Rubber feet on the underside of each coaster protect the table. Made of natural gemstones, the pattern, color, and shape will vary, and each set is as unique as the recipient. Gift boxed.
