The increasing question of those who are about to buy coral stone about how to detect the original coral stone from the fake, so we discuss in this article the most effective ways and means to do this diagnosis based on known and confirmed tests in the middle of the gemstones.
By performing a series of tests or based on one of them individually, it depends on how determined you are to ascertain whether the coral stone in front of you is genuine or a fake made in a laboratory. The more tests you perform, the more certain you are of the results. Therefore, we review the most successful and reference tests with an explanation for each of them, knowing that they are very simple and do not require the availability of in-depth experience in the field of gemstones or even special tools. Where these tests are conducted using tools available and found in every home.
1. Coral stone test by milk
Examination of natural coral jewelry
This test is simple and easy, so you can apply it at your home without the need for expensive special means. Well, get a cup and pour the milk in it until it is full to the center and note the color of the milk in the cup, now put a coral stone inside it. You can now notice the change in the color of the milk to the color of the coral used in the most common cases, its color is red, so we will notice in this example that the color of the milk changes to a red color gradually as the milk absorbs the original and natural color of the coral stone. Whereas if the stone is fake and artificial, the color of the milk will not change and it will remain on its color as it is white.
2. Wear Test
Wear the coral stone for several days, you will notice that it affects your health condition. When your health is not good, you will notice that the color of the stone has become faint or becomes very pale once you are affected by a health problem. In addition, there is something special about this stone, it is supposed to restore its basic color once you recover from this health problem. The property of discoloration is normal for the original coral stone, while it is the opposite in the case of artificial coral, so this is a simple and good way to detect the quality of the stone.
3). Friction test

When we perform this test by rubbing this stone, we notice a change in the sound that it emits compared to the sound The result of the process of friction of the fake stone, where the unnatural coral is often made from one of the materials close to glass. When the non-original coral stone is rubbed, it produces a sound like the sound of glass rubbing, while the case is different for the real stone.
4. Lens Magnification Test
Detection of original and natural coral by a magnifying glass test
Bring a magnifying lens, if possible. In the gem store, use the lens to set the coral stone you wish to view or purchase on one of the white cloths, provide adequate lighting, and then examine the stone via the magnifying glass. The original red stone, for example, does not have any unnatural-looking granules on its surface. It should seem smooth without them, but in order to complete that test more correctly, the quality of those grains must be determined, and this is one of the most difficult tests to discern between a real coral stone and a fake. 5. Turmeric examinationReal Blue Coral
Bring some natural turmeric and then rub it against the coral stone; if the coral is natural, it will not turn the turmeric red; if it is not natural, you will detect red streaks on the turmeric or it will be on its way to redness. (It is also regarded one of the exams with a particular level of difficulty.)
