Our logo-embellished coasters are handmade by highly trained artisans from tumbled Botticino marble quarried in Italy. Each is cork backed to prevent any damage to fine home furnishings. The elegant winery logo in 4 different label designs gives each one a distinct old-world look and feel. The color refers to the cross in the logo design. Our Sauvignon Blanc Marble Coaster (light green) is one of four different styles to choose from.
