Ruby Gemstone Identification

How To Tell If A Ruby Is Real

Nowadays, the demand for rubies is very high in the market, and people fail to recognize the difference between real and fake rubies. When people don’t know the difference between natural and synthetic rubies, it becomes easy for a few sellers to sell duplicate gems at real gem prices and make money out of them. Here are some easy test by which you can identify real one. For this, first understand rubies type; 


Natural ruby, also known as Manik stone, forms beneath the earth’s surface under specific environmental and temperature conditions. Human involvement is limited to cutting and polishing, which gives the ruby its divinity, radiance, and vibrancy.


Synthetic ruby is made in a lab with the same chemical composition as natural ruby. It is made by melting aluminum oxide. The pulverization of the components, melting, and recrystallization in the same atmosphere and conditions as natural ruby are all part of the method. Since it is made from the same chemical composition as a natural one, the physical and chemical qualities of the ruby remain the same.


An imitation is something that does not fall into either of the above categories. Simply put, it imitates ruby but is a different stone, it can be natural as well as synthetic.

Now the thing worth noting here is that different methods are adopted while separating synthetic and imitation of Ruby. We cannot separate the two by the same tests. So let us know about these easy methods;

(How to Differentiate From Synthetic)

We will now discuss some tests, such as the ruby breath test, ruby light test, and fluorescence test, that can be used to determine the originality of a ruby.

1. Ruby Breath Test

The Ruby Breath Test is also known as the “fog test.” Since rubies are efficient heat conductors, this technique works best. Take a ruby in your hand and bring it close to your mouth by exhaling on it. If your ruby is real, it will evaporate within 2 seconds. mostly in a single second. If your ruby is fake, it will take 1 to 2 minutes, sometimes more than that.

2. Ruby Light Test

For the Ruby Light Test Get yourself into the dark room. Then take a sharp white light and keep it pointed towards the ruby. Observe the color that comes out of the ruby. It is real if there is a red flash; otherwise, it is not. This happens because it has high iron content and is naturally derived.

3. Check Fluorescence

Natural rubies typically show weak to moderate red fluorescence under longwave UV (ultraviolet) light. Some natural rubies from specific sources, such as Burmese rubies, may exhibit a stronger red fluorescence. Mostly synthetic rubies show no Fluorescence under UV light.

4. Microscopic Study

Examine ruby with a microscope, you will find little inclusions that are not visible to the naked eye. If you see fake rubies under a microscope, you will find them almost flawless. For this, hold your stone at a 45-degree angle in the light. Make sure you are able to see through it.

1. Color Comparison

Some stones look like rubies like garnet and red spinel. Real rubies have a deep red color with a slight purplish or pinkish hue as compared to red Garnet and red Spinels. Red garnets are lighter red with a purplish or Brownish Hue. Red Spinels are also lighter red with pinkish and Orange Hue.

It’s important to note that the ability to differentiate between these gemstones by color alone may require a trained eye and experience.

2. Observe Facets Closely

Examine the ruby’s surface with a 10-power handy lens and check the facets. If you find round, and smooth facets, it is a synthetic stone. Real ruby has always sharp edges.

3. Scratch Test

Ruby is among the hardest stones found on Earth. It is very hard to break them. Scratch it with a coin or any other hard surface, such as stone or hard metal. If you are able to do it, then it is certainly not a real one.
You can rub it harshly on a flat surface. If the ruby leaves any residue then it is a fake ruby. Always Remember the real Ruby Never Leaves residue on rubbing or scratching.
