  • - a clean glass vessel;
  • - water;
  • - cow's milk;

Step 1

A large, deep, bloody ruby ​​and a low price are nonsense. Such stones are very rare (as a rule, these are the famous Burmese rubies) and are close in value to diamonds. If you are offered to buy a large stone of intense red color for a small price, be sure that they are trying to sell you a fake.

Step 2

Place the ruby ​​in a clean glass jar. A reddish spread on the glass will indicate that this is a real stone.

Step 3

Dip the ruby ​​in the cow's milk. If the ruby ​​is genuine, the milk will take on a pinkish tint. If the milk remains naturally yellowish, the ruby ​​is fake.

Step 4

Place the stone in your palm and, slightly swaying on the weight, feel its mass, weight. Natural ruby ​​is noticeably denser, heavier than glass.

Step 5

Our eyelids are very sensitive to heat and cold. Considering this property, do the following experiment: put the ruby ​​on the eyelid and concentrate, listen to the sensations. A trinket imitating a ruby ​​(glass, plastic or pebble) will quickly heat up and you will no longer feel it for your eyelids. While an authentic ruby ​​stays cool for a long time.

Step 6

Place the ruby ​​under a UV lamp. The real stone will remain the same color, the fake one will change color. It will most likely turn orange.

Step 7

Look at the facet of a ruby ​​first from one angle and then from another. In one case, this part will be dark red, in the other it will be paler.

Step 8

In a real ruby, the bubbles, if any (which is very rare), have a round shape and the same color as the stone itself. In fakes, the bubbles are white, often empty, "opened".
