UNUSUAL PROPERTIES: These lab-created and manufactured forms of opal result in stronger beads and stones, opening up creative options for jewelry makers. Opals are occasionally treated with soaking in waxes or synthetic lubricants to enhance luster and stability. Opal is a stone of inspiration which enhances imagination and creativity. It can bring inspiration to projects and to life and Spirit.
TREATMENT: Man-made simulated opals are manufactured in two ways. Some opals are cut from opaline silica grown in a laboratory, taking over a year to grow and come into their colors. This slow growth results in a similar structure and material balance as natural precious opals, but with increased durability and structural stability. Gilson opals contain approximately 70-75% silica (similar to natural opal) within a trade secret base of translucent plastic or resin. Simulated opals do not contain water like natural opals do–making them less vulnerable to changes in temperature, humidity and heat.
USAGE: Earrings, bracelets, beads and any other jewellery
