Bacon Opal / Candy Stripe Opal

Bacon Opal / Candy Stripe Opal is found in the Mineral Mountains north of Milford, Utah. The Thomas Mountains were formed as a result of Tertiary volcanic activity and mineralization in the mountains is very diverse. The opal is formed as a result of geothermal fluids flowing through volcanic rock layers. The bacon appearance is a result of various iron minerals such as hematite, which give the opal layers a red color. The color bands in this material are very unique and make fun, colorful cabochons. Although this material is found in Utah, it is not common on the market and most jewelry currently made from it is made over seas. Bacon opal is a hyalite opal, which is generally colorless, but the mineral impurities give it a wide range of colors. This opal is also UV reactive.

The layers of the bacon opal are very delicate and it is advised to stabilize this material before cutting for cabochons. I have made cabochons without stabilizing, but you have to be very careful.

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. This material has a lot of pits and druzy cavities between the layers. 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!
