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 opal does not fall victim to color fading and is resistant to chemicals such as acetone and alcohol.
