Cultured Opals are a lab created stone. It was a project started some 20 years ago by a turquoise fanatic and chemist. Lab created opal is pretty but gets dull, and it just doesn’t really capture the light dispersement that real opals do. This was because no one was really getting those silica dioxide particulars small enough to mimic Mother Nature. The nano particles of silica dioxide are just the same as natural opal. They are almost as small as an atom. The matrix is a nod to turquoise and the two together are magic. It takes about a year to grow. It is more durable than natural opal and this makes this material ideal for rings and bracelets as detergents won’t hurt it. It has a hardness of 5.5 on the Mohs scale.
