Flowering Tube Onyx

The family that found this material in central Utah called it Flowering Tube Onyx and usually just called it Tube Onyx. Tube onyx is beautiful worked into cabs. It is tricky to work, because heat buildup while grinding it causes it to separate along the distinctive banding. You can stabilize the material to get past this issue, or you can try backing it with a thin slab of a more stable rock, such as petrified wood or bassanite, or epoxy.

Please enlarge and view the photographs for more detailed views. Shown wet to simulate polish. As with all natural rock, there may be fractures or pits to seal or work around. Each slab has the approximate dimensions listed. I use the longest and widest point and the thinnest, it’s not averaged.

We have worked hard with the lighting and the settings on the camera so that the colors are very accurate. Individual settings may affect color viewing on various devices and I cannot predict what your device will do, but on my computer, they’re dead on for color. I appreciate your business!
