Sardonyx - Calcite Onyx Slabs

Sardonyx – Calcite Onyx Slabs

This sardonyx is from the Thomas Mountains of Utah. The Thomas Mountains were volcanically active about 50 million years ago and the geothermal fluids from the magmas infiltrated the surrounding rock, depositing opal and chalcedony, micro-crystalline quartz, in the form of onyx.

The sardonyx has lacy bands of translucent white with orange and red or blue. It is a beautiful and elegant stone for that special night out. The orange sardonyx is reminiscent of a beautiful, bright sunset while the blue will remind you of the tranquil ocean waves.

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 I do my best to make the colors accurate. I appreciate your business!
