Simulated Diamond

What is a simulated diamond? When buying a piece of imitation jewelry we come across the word simulated diamond. But what does it mean? Diamonds are the most beautiful part of any jewelry whether they are real or imitational. So today let’s now about what is a simulated diamond?

What Is A Simulated Diamond?

Simulated diamonds are the same as real diamonds in looks but they are completely different in the make. They do not have the same chemical, physical or optical properties as real diamonds. Even they are cheaper than real diamonds.

Simulated diamonds are also known as diamond simulants.

What Are Simulated Diamonds Made Of?

Simulates diamonds are made of synthetic and natural gems that look like a particular gem are used in imitational jewelry. Natural materials like colorless quartz, topaz, sapphire, beryl, and zircon are used for simulant diamonds for centuries.

Most commonly the simulant diamonds like zirconia and moissanite are synthetic stones that are made in laboratories whereas cubic zirconia is an example of a diamond that is made by heating powdered ingredients at a melting point and then cooling the mix to a solid form.

Diamond Simulants

Below are some diamond simulant that not only looks real they can be cleaned easily

  • Cubic Zirconia (CZ)

Cubic Zirconia is a very affordable simulated diamonds. They have a hardness of 8.5 and are commonly colorless and flawless. They have a bit greater fire than diamonds

  • Synthetic Moissanite

Synthetic Moissanite is the hardest diamond simulants and has twice more fire than diamonds. These can be colorless and even nearly colorless. They have high clarity and are less likely to attract grease.

  • Zircon

Zircon is a natural stone and one of the oldest on earth. It has the fire same a diamond

  • Sapphire

The colorless Sapphires are both hard as well as tough. It is extremely durable and can be worn in a ring. The colorless sapphires are affordable and look like real natural stone

  • Gadolinium Gallium Garnet (GGG)

The Gadolinium Gallium Garnet has the same fire as the diamonds. They are often colorless.

  • Yttrium Aluminum Garnet (YAG)

The Yttrium Aluminum Garnet or YAG has good hardness and is highly clear. They are rarely used as simulant diamonds.

  • Synthetic Rutile

If you want a diamond that looks more brilliant than a diamond then Synthetic Rutile is the best choice. It has 7 times more fire than diamonds

Are Simulated Diamonds Worth Anything?

Simulated diamonds look gorgeous but they do not have the same chemical or physical properties as real diamonds have. They are relatively cheaper than the diamonds but are not outrageous.

The Difference Between Simulated Diamonds And Real Diamonds?

The simulated diamonds and real diamonds look the same but have different chemical and physical properties. Although the simulated diamond jewelry look no less than real ones

Do Simulated Diamonds Get Cloudy?

The synthetic diamonds that are grown or manufactured in the laboratory have very minor inclusions or blemishes. These imperfections can be the same as the ones that can be found in top-grade diamonds but are not visible and they won’t cause a cloudy appearance.

What Is The Best-Simulated Diamond?

  • Cubic Zirconia (CZ)
  • Synthetic Moissanite
  • Zircon
  • Sapphire
  • Gadolinium Gallium Garnet (GGG)
  • Yttrium Aluminum Garnet (YAG)
  • Synthetic Rutile

Do Simulated Diamonds Test Real?

Yes, lab diamonds have the same carbon composition as natural diamonds. Therefore, they have the same thermal conductivity. The test results are positive when exposed to the diamond tester, since the diamonds have the same physical and chemical properties as natural diamonds.

Does Simulated Diamond Mean Fake?

Simulated diamonds are generally identifiable as fake diamonds, even to the untrained eye. One of the most popular diamond simulants is cubic zirconia, which can be purchased at a low price in many big box stores. Moissanite, a newer simulant, is also used as a diamond alternative.

How Long Do Simulated Diamonds Last?

This means that—just like a mined diamond—a Lab Created Diamond will last a lifetime and beyond as long as they are cared for properly. This includes cleaning your ring regularly and—as you would with a mined diamond—protecting it from chemicals and lotions.

Will Simulated Diamonds Pass Diamond Test?

Yes, some diamond simulants can pass a diamond tester.
For example, moissanite, a man made gem, may pass as a diamond on a standard tester pen. This is because moissanite also has very high thermal conductivity! Other diamond simulants, such as CZ, will not pass the tester.


Diamonds are a women’s best friend no matter real or stimulate diamonds. Whenever you are about to buy a simulated diamond you must check the durability as it affects the price and the care of the diamond. No matter which is the diamond it will shine till you take proper care of it. We hope next time when you are about to buy a diamond you now know what is a stimulate diamond and will buy accordingly.
