This piece of amber onyx was cut from the mine in Utah recently. If you want, you can even go to the mine and choose what piece you want for your house. Notice how the sunlight shines through it. Be sure to think how this unusual material could really make your house stand out from the crowd. The cost is similar to granite. I have seen this used where a window would go to filter light into a bathroom. Small shelves can be made with a light underneath in an art niche.
