Color Description:



Pearl White Lab Opal is inspired by the glistening Pearl birthstone. This white opal is complexly layered with red, green, and blue fire. A deep dive into the vast ocean could be the only way to recover one of the most mesmerizing materials in the world. This could be your next big catch of the season.

What is Pearl White Lab Created Opal?

Pearl White 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 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 stones. The stones are cut and perfected into the many different sizes we offer. Due to the layering of vibrant bursts of color this makes each stone unique with it's 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.
