How to distinguish a fake

Before buying, pay attention to some important points. Chalcedony is easily affected. For example, they can change color to almost any other. They absorb the paint well, completely changing the shade and preserving the transitions from dark to light tones. Heating to high temperatures also affects color. From some rocks in this way you can get stones that are very similar to carnelian.

Sometimes it looks pretty good. But true connoisseurs prefer the natural palette. In addition, unscrupulous sellers often simply hide this fact.

Another type of fake is also common. For example, a highly regarded variety of chalcedony, which jewelers call "grapes." Nuggets are a cluster of red-brown balls and have high decorative properties. For the purpose of falsification, grinders simply grind such a form from low-quality rock, passing it off as a natural original. This phenomenon is especially common in the Far East.

Well, of course, do not forget about the certificate. In most cases, this is a sufficient guarantee of quality.

Selection rules

In order not to doubt the quality of the purchase, treat it carefully and responsibly. Remember that natural stone cannot be perfectly smooth. This applies to both shape and color. Screaming shades are a sign of fake. And just coloring natural gems is not the only way to cheat! The stone may generally be made of plastic or glass.

Chalcedony Care

Buying natural stone is not all. Absolutely all chalcedony needs care. Varieties of green stones, for example, are afraid of high temperatures. And black ultrasonic cleaning is contraindicated.

There are general rules for all minerals. Jewelry with chalcedony should not be stored in the bulk, because the stones can be damaged on the sharp edges of more durable gems. It is recommended to remove jewelry during sports - the effect of sweat adversely affects this stone. In no case should you clean chalcedony with acetone, alcohol, aggressive chemistry. Their wonderful coloration may suffer from this. And noble translucency will turn into a banal turbidity.

If the product is stained, it is best to clean it with soap and water. After completing the procedure, traces of the solution must be carefully washed off with running water.
