Our coaster gets its unique beauty from inlaid tiles of natural horn, prized for centuries for its distinctive markings and translucent warm color. Artisans hand polish the select pieces of salvaged water-buffalo horn and set them in gleaming nickel plate, creating an appealing contrast in texture and an elegant presentation for wine and Champagne. Skillfully hand inlaid with salvaged buffalo horn. Crafted of durable sand-cast aluminum. Hand wash or wipe clean.
