Real agate slices are inlaid with a delicate brass bee for these super chic coasters. The agate is protected by an invisible slice of acrylic making these unique coasters feel substantial, despite how light they are. These are truly works of art. Agate is a semi-precious stone and has variations...so don't expect them all to look the same! Agate, brass and acrylic. 2.5" x 3.5" x 0.25". Packaged in a gift box.
