Recognizing fake stones is a necessity that can happen in life on several occasions. We can buy jewels or choose coatings or other types of furnishings such as marble. In these cases, the scam is always around the corner. A dishonest seller knows many techniques to persuade the customer to buy seemingly real stones. Often this expense is linked to the emotions of the object. The feeling is likely to focus attention more on aesthetics than on the quality of the stone. So it is useful to know how to tell if a gemstone is real at home, to avoid the so-called "scams".
