“Play-of-color” is the most important feature to differentiate lab-made opal from the other man-made opals as it resembles the beauty of natural precious opal. For example, you may see plastic or glass being claimed as man-made opal. But they do not have any opal’s color effect.

Lab-grown opal is the only man-made opal which has vertical fire pattern, the unique growth pattern. For cabochon or sheet product, you can easily observe if there is any columnar structural growth horizontally.

Lab-grown opal quality will not change over time. Unlike natural opal which may have dehydration or cracking problem. Lab-grown opal is also easier to preserve over time.

Bello Opal and Bello Jelly Opal contain 20% resin, so they cannot apply to glass blowing art. If you are looking for glass compatible product, please inquire for "Bello Galaxy Opal” which is resin free.

Bello Opal, Bello Jelly Opal and Bello Galaxy Opal , which are classified as high quality lab-grown synthetic opal, will not be damaged by jewelry plating process.
