How to tell if a diamond is real?
With a variety of diamond simulants on the market including cubic zirconia, moissanite, it can be hard to tell if your stone is a true diamond.
Follow our 3 simple tests outlined below to tell if a diamond is real or a fake.
Diamond home tests vs expert evaluation
Our experts shared their top tips and home tests for spotting a fake diamond. While there are many more tests to spot a fake diamond some can be problematic.
For example thermal conductivity tests and scratch tests. While these would not damage a real diamond but could impact gemstones. Diamonds score 10 on the Mohs Scale of Hardness, however other gemstones do not.
However, it is always recommended to have a GIA trained gemologist examine any stones you are unsure about. Why? An important distinction a gemologist will be able to make beyond whether your diamond is real or not is:
- The type of diamond
- The quality of the diamond
Types of diamonds
After establishing that your diamond is real, a trained gemologist will also establish what kind of diamond you own. This could be a:
- Natural diamond
- Treated diamond
- Synthetic/lab created diamond
While these will all look the same to the naked eye, they are in fact very different. It is also important to note that have different values.
1. Natural diamonds:
- Definition: a diamond mined from the Earth.
- Value: resale value of a natural diamond typically 25%-40% of what is what is was purchased for at retail.
2. Treated diamonds:
- Definition: a diamond that has undergone a treatment of some description to enhance either the color or clarity of the stone.
- Value: treated diamonds are typically worth half the amount of natural, non treated diamonds.
3. Synthetic diamonds:
- Definition: a diamond that was man-made, i.e. created in a laboratory and not mined from the Earth.
- Value: synthetic diamonds are typically worth half the amount of natural, non treated diamonds.
A gemologist can also ascertain the quality of the diamond which will help establish its worth.
Gemstones that look like diamonds
There are many stones that frequently get confused with diamonds. Common diamond simulants and diamond substitutes include:
- Cubic Zirconia: often abbreviated to CZ, cubic zirconia is a popular diamond substitute. A low cost, highly affordable alternative to a diamond, cubic zirconia is a man made mineral. To the untrained eye, cubic zirconia strongly resembles a diamond.
- White Sapphires: A colored sapphire with a much lower price point than a natural diamond. The gemstones often have noticeable cloudiness.
- Moissanite: Naturally occurring moissanite is extremely rare. Moissanite used in jewelry is lab created and very affordable.
- White Topaz: Topaz has an 8 on the Mohs Scale of Hardness whereas a diamond has a 10. Which simply means that Topaz is far more likely to scratch than a diamond. This will go on to affect the gemstone’s sparkle over the years as the stone scratches with daily wear and tear.
HOW MUCH IS A DIAMOND WORTH?
When a gemologist analyzes a diamond, they will establish the 4 C’s of the stone. These are:
- Diamond Carat Weight: the weight of the diamond measured in carats (ct). The larger the carat size, the more valuable the stone. You can also calculate your diamonds’ carat weight by using our online diamond calculator.
- Diamond Color Grade: this measures how much yellow there is in the stone. Diamond color grades in white diamonds range from D (colorless) to Z (faint yellow). The less color in the diamond, the more valuable it is.
- Diamond Clarity Grade: this is an indicator as to how flawed the stone is but internally and externally. Note that most flaws in a diamond cannot be seen by the naked eye. Although a diamond may seem flawless, this is most likely not the case as flawless diamonds are very rare. And therefore very valuable.
- Diamond Cut Grade: this refers to how well a diamond was cut and the overall proportions of the stone. A well cut diamond emits light more effectively and creates the sparkle that diamonds are known for.
These 4 C’s will play a pivotal role in establishing how much your diamond is worth. Professional diamond buyers will take these characteristics into account to calculate the value of your stone on the secondhand market.
A good rule of thumb is the following: you can typically expect to receive 20% to 50% of what was paid at retail. Jewelers have high mark ups as diamond jewelry is slow moving inventory and they have high overhead costs such as rent and insurance. This means that the diamond will be marked up to cover these costs.
