KILAUEA Men’s Polished Tungsten Wedding Band with Black and Gray Lava Rock Stone Inlay and Polished Beveled Edges - 8mm. A volcano that now sits dormant on your finger. This stylish and handsome Tungsten 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. Tungsten has much higher durability than gold, platinum, and steel.
