VESUVIUS Men’s Polished Black Ceramic Wedding Band with Black and Gray Lava Rock Stone Inlay and Polished Beveled Edges From the volcano to your finger. This stylish and handsome Ceramic wedding band has glossy, polished edges with bevels. It’s the inlay that takes center stage, however, with a mashup of black and gray lava rock. It looks as if a channel of lava once flowed through the band, only to harden, leaving it in its current state. Polished beveled edges encase a stunning gray and black lava rock inlay. Ceramic has much higher durability than gold, platinum, and steel. Since Ceramic does not contain nickel it’s hypoallergenic.
