The main problem of a person buying a ruby is to determine its authenticity. There is a simple and reliable solution to this problem - consultation of an experienced jeweler or gemologist. You can also give the stone to experts who will check, evaluate it and issue a conclusion using professional equipment. However, you can do it yourself and, knowing several ways to determine the authenticity, save yourself from buying a fake stone.
Necessary
- - a clean glass vessel;
- - water;
- - cow's milk;
- -
Instructions
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".
