They are also known as diamond simulants, diamond imitations, or imitation diamonds. Simulated diamonds are often much less expensive than natural diamonds, but they are not as durable or valuable.

Are diamond simulants expensive?
Compared to natural diamonds, simulated diamonds are much less expensive. For example, a 1-carat simulated diamond may cost around $500, while a 1-carat natural diamond may cost $5,000 or more.
Will simulated diamonds last?
Simulated diamonds can last for many years, but they are not as durable as natural diamonds. Natural diamonds are the hardest natural substance on Earth, while simulated diamonds are made from softer materials, such as cubic zirconia or moissanite. This means that simulated diamonds are more likely to be scratched or chipped.
Simulated, Natural, and Lab-created Diamonds
Here is a table that summarizes the key differences between simulated, natural, and lab-created diamonds:
Characteristic | Simulated diamonds | Natural diamonds | Lab-created diamonds |
---|---|---|---|
Composition | Different materials, such as CZ, moissanite, and white sapphire | Carbon | Carbon |
Hardness | Softer than natural diamonds | Hardest natural substance on Earth | Hardest natural substance on Earth |
Durability | Less durable than natural diamonds | Highly durable | Highly durable |
Value | Less valuable than natural diamonds | Most valuable | Less valuable than natural diamonds |
Cost | Much less expensive than natural diamonds | Most expensive | Less expensive than natural diamonds, but more expensive than simulated diamonds |
What is the difference between simulated and natural diamonds?

Natural diamonds are formed under extreme heat and pressure over millions of years. Simulated diamonds, on the other hand, are created in laboratories using a variety of methods.
One of the main differences between simulated and natural diamonds is their chemical composition. Natural diamonds are made of carbon, while simulated diamonds are made from a variety of materials, such as cubic zirconia, moissanite, and white sapphire.
Another difference is their hardness. Natural diamonds are the hardest natural substance on Earth, while simulated diamonds are made from softer materials. This means that simulated diamonds are more likely to be scratched or chipped.
Simulant diamonds vs lab created

Simulated diamonds are different from lab-created diamonds. Lab-created diamonds are real diamonds that are grown in a laboratory environment. Simulated diamonds, on the other hand, are not real diamonds. They are made from different materials and do not have the same chemical or physical properties.
Will simulated diamonds pass a diamond tester?
Most diamond testers will be able to distinguish between simulated diamonds and natural diamonds. However, there are some simulated diamonds that are so well-made that they may be able to fool a diamond tester. If you are unsure whether a diamond is real or simulated, it is best to have it evaluated by a professional gemologist.
Simulated diamonds can be a good option for people who are looking for a beautiful and affordable diamond alternative. However, it is important to be aware of the differences between simulated and natural diamonds before making a purchase.
