There are a lot of deceptive techniques that are used to mask over cheap jewelry to make them appear to be of more value. For instance, a single speck of paint placed in a strategic spot on a gem can make it reflect throughout the stone, giving it the illusion of value. Here are a few examples of these sneaky methods to look out for.

Painting and Foil Backing

Using paint or another colored material underneath the gemstone to improve its color is one method that some will use to make the diamond look more valuable. The right speck of paint placed in just the right spot on the diamond will cause it to reflect and shine throughout the entire stone.

Along the same lines as this, foil backing can also be used. This technique is akin to jewelry with closed back settings. To avoid being caught in these snares, simply avoid purchasing jewelry with closed backs. Unless, of course, the item in question is an antique. If you really want to be ensured that the gemstone you are purchasing does not have a foiled backing, check out these tension set rings.

Crackling and Composite Gemstones

Man-made jewels are worth far less than natural stones. They have a somewhat fake look to them as they do not contain the flaws you will find in natural diamonds. To make these stones look more natural a method known as "crackling" can be used by applying thermal shock to the diamond.

Another sneaky trick that can be played is actually gluing two or more stones together to make a bigger, and better looking gem. Although, this method is commonly used in assembly opals and is not considered to be a deceptive practice. However, this method is used with gemstones such as Sapphires or Rubies to trick the consumer into believing they are purchasing a single large stone. Some jewelers will even use a large, fake glass stone at the base, and glue a small geniune stone to the top.

How to Spot a Fake Stone

Spotting a fake stone for the average consumer is not easy. There are many, many more methods than listed above to watch out for. Unless your eye is professionally trained, you can easily fall into such snares. The only true way to ensure that the stone you purchase has not been treated using these sneaky methods is to buy from a reputable jeweler. Or if you have already made your purchase, such jewelers can spot these tricks from a mile away and will be glad to reveal to the consumer what treatments it has received.
