What is Black Fire Lab Created Opal?
Black Fire Opal is a synthetic lab-made material that consists of Silica and Polymer rather than hydrated silica (natural opal). The polymer stabilizes our opal which in turn makes it easier for jewelry making. You will experience less cracking and crazing that can be detrimental when using natural opal in jewelry. By using a polymer it also creates a slightly softer product making it superior for turning and cabbing. Our crushed opal does not fall victim to color fading and is resistant to chemicals such as acetone and alcohol.
Our Lab Created Opal takes around one year to grow in a controlled environment. This is a complex process of layering to create the unique color patterns. This complex process is used to then create a rough cut of synthetic opal that is then made into cabochons. The cabochons are shaped and perfected into the many different sizes we offer. Due to the layering of vibrant bursts of color this makes each cabochon unique with its own blend of colors and patterns.
Please keep in mind that the material can only withstand heat up to a rough estimate of 250 degrees Fahrenheit. Please proceed at your own risk.

These are wonderful! I milled a flat bottom shallow hole in a ring channel to hold it. Then paired it with "Black Fire" and it's great! Lots of fire & color.
