With the advanced technology, synthetic or man-made gemstones are as beautiful as the genuine ones. Fake opals are fairly difficult to identify. Some dealers may offer fake gemstones instead of natural one. Here are some ways from experts for you to identify a fake opal.
Obviously, the first sign of a fake opal is the low price, which is important to attract people. Use a loupe to look at the opal closely. With the loupe, you can find out more intricate details inside the gemstone. The higher your magnification, more apparent it will.
Look at the gemstones at all sides. You will have more chances to find the differences.
Look at the color. The uneven color means a poor dye or paint job. It is easily to mistake dyed opals for the higher priced blue opal.
Consider taking a gemstone class or workshop to gain experience. Try to compare real opal with fake to get first-hand information.
Don't hesitate to ask information from dealers or jewelers.

Knowing these, you will find your favorite opals at good price. And you can help your friends to identify the gemstones before buying.
