Aerin - Agate was given its name by Ancient Greek philosopher Theophrastus – who discovered it beside the Achates river in the 4th century BC – and Aerin’s brown coasters capture the fascinating irregular quality of the stone. They have intriguing asymmetric silhouettes that are made all the more captivating by the gold-plated edges. Place them on your coffee table to bring a sophisticated air to an intimate gathering at home.
