Description

Lab-created opal is a type of synthetic opal that is created in a laboratory setting rather than being formed naturally in the earth's crust. The process involves growing tiny particles of silica in a controlled environment to form opal. The resulting lab-created opal has physical and chemical properties that are very similar to natural opal, including its color, hardness, and chemical composition. However, lab-created opal can also have some advantages over natural opal, such as being more durable and having a more consistent color and pattern. Lab-created opals are often used in jewelry-making and are a popular choice for people who want the look and beauty of natural opal but at a lower cost. They can also be used in scientific research, as their properties can be controlled and studied more easily than those of natural opals.
