What is Black Emerald Crushed Opal?

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

Crushed Opal takes around one year to grow in a controlled environment. This is a complex process of layering to create the unique color patterns. The first form of synthetic opal is a rough cut of stone. This rough cut synthetic stone is then crushed down and sifted into the desired stone sizes. After our testing we determined the perfect stone sizes to offer; Large, Medium, Fine, and Powder forms. 

Our crushed opal is weighted to be like natural stone, unlike a lot of glitters. Glitter is almost weightless, where our products are of a much higher quality than glitter.

Our photos are representing our crushed opal by what it will look like "wet" or when added to your project. Adding an adhesive, glue, resin, nail polish, and/or etc. to our opal brings it to life. Opal will look best in natural lighting or once added to your project. The crushing process may make the stone pieces appear less colorful to the naked human eye but do not be fouled this product comes to life once in use. Fine sized can look lighter in color due to the crushing process, but once again will brighten up with use. Our Crushed Opal may not be as vibrant until in use. Please try our products in your project for best color results. *Color on your screen can appear differently from device to device, please keep this in mind.

    Perfect for inlay projects

    These are as good as any of the higher priced crushed opals I have purchased elsewhere. The colors are brilliant and the various sizes available make them great for a range of projects. I purchased the medium for my inlay projects which allowed me to pack them tight in the groove to eliminate voids yet retain the brilliance of the opal color.
