Cultured Opal

Easy Inlay’s jewelry-grade cultured opals contain the fire typically seen in rare opals and are optically, physically, and chemically identical to those found in nature. No one else sells 2-3 mm grains, large brilliant facets of noticeable fire that fill larger voids. They're versatile and are easy to crush to fill smaller spaces, too. (Learn how to make your own DIY mortise and pestle here.)   

Unlike natural stones, the color, luminosity, and brightness of these opals will not fade over time. Our opals add a pop of color that catches the light and the eye; professionals and crafters alike simply insert the grains into any void, small crack or knot; or blend with Easy Inlay’s mother of pearl to add visual depth and dimension. They're contained in easy-to-store jars, too.

In the lab, these opals can take about a year to grow. Made from approximately 80 percent silica, scientists arrange spheres in a lattice pattern to imitate the structure of a jewelry-quality opal. Then they stabilize the pores of the structure with silica gel; the result is an opal that exhibits the fire and iridescence of their natural, more expensive counterparts.
