Whether you are purchasing diamonds as an investment, gift or a personal luxury, you need to be sure that they are real and the seller is not going to rob you of a large sum of money. The prospect of making an unworthy investment that can devoid you of your life’s savings is worrisome. Here, we have a few suggestions that can resolve this problem by helping you decide if a diamond is real or not.
The Dot Test
Here is an extremely simple test that can validate the authenticity of the stone.
Take a blank paper and make a dot on it with a pen. Now, take the stone and place it on the dot with the top side facing downwards. Make sure that the dot is in the center of the stone. Look at the dot directly from the top. If the stone’s a fake, you will see a circular reflection. If it’s real, you will see a broken reflection that covers almost the entire width of the stone.
Scratch and Scuff!
Checking the pureness of a stone is a lot easier if it is loose. There are a few non-scientific tests that can give you a peace of mind regarding the authenticity of the stone in question. Diamonds are the stones present on earth with a rating of 10 on Mohs scale. If you scratch it on a glass, it will leave a mark. But be careful because it’s a risky test as itcan destroy the appearance of the rock and render it worthless.
This test can also be conducted on sandpaper. Scratch your stone briskly on dry or wet sandpaper. If it tears up or leaves behind a scratched surface, it’s a fake!
The Fog Test
Bring the diamond close to your mouth and fog it like you would glass. If heat disperses, your diamond’s a real deal and vice versa. Pure diamonds clean up faster compared to fake ones and this will be evident if you fog a real and a fake diamond simultaneously. Secondly, if you fog the fake diamond repeatedly, you will notice that condensation will start to build up on the stone whereas a real diamond will clean itself instantly.
The UV Light Test
When a real diamond is kept under black light or UV light, it exhibits blue fluorescence. However, this property is only demonstrated by fluorescent diamonds. Therefore, the absence of blue only indicates that the diamond in question is a non-fluorescent one. If the light causes the diamond to exhibit yellow, green or gray fluorescence, the stone can be a Moissanite.
The Heat Test
This is one of the most effective diamond authenticity tests. Pure diamonds are resistant to heat because their composition causes it to disperse and hence, keeping the diamond cool. Take a heat probe and bring it in contact with the diamond for 30 seconds. If it doesn’t heat up, you have got the right stone! The best part about this test is that it can be conducted free of charge and several jewelers will allow you to do so because it causes no harm to the stone.
Look At the Mount and Setting
Expensive diamonds are complemented with expensive and quality setting. You will never find a quality stone set in a cheap metal setting. If you do, know that it’s a fake! Look at the stamps present inside the setting they will tell you the quality of the platinum or gold such as 10k, 14k or 585PT, 900 PT etc.
The Weighing Test
When you compare the weight of a fake diamond to a real one, you will find that the former weighs more. It has been observed that cubic zirconia weighs 55% more than the real diamond of same size and shape.
Consult a Gemologist
After you have selected the stone, ask the jeweler to allow a gemologist to examine the stone. They can provide you with a detailed report confirming the authenticity of the diamond and can even inform you about the quality of the stone.
When you are out to purchase diamonds, don’t go for just anyone available in the market; find a reliable seller or jeweler.
