Light Transmission: Moderate translucency — light passes through the slab, making backlighting a highly recommended installation technique to bring out its warm amber and honey tones

Appearance

Lava Onyx features a base color of rich amber to warm honey, intersected by a dramatic, web-like network of dark brown to near-black veining. The pattern is reminiscent of cooled lava flows, giving the stone its name. No two slabs are alike — each piece is a one-of-a-kind natural composition.
