Moissanite, lab-grown diamond, or natural diamond – which one to choose?
When choosing an engagement ring or other piece of jewelry featuring a gemstone, one of the most common questions is: moissanite, lab-grown diamond, or natural diamond? All three stones are beautiful, yet they differ significantly in terms of origin, price, and optical properties. In this article, we explain the differences and help you decide which one is the best fit for you.
What is a moissanite?
Moissanite is a lab-created gemstone composed of silicon carbide. Although moissanite was originally discovered in meteorite fragments, it is extremely rare in nature; therefore, all moissanite used in jewelry today is grown in a laboratory. Moissanite is known for its impressive brilliance and "fire," which are often even more pronounced than those of a diamond.
What is a lab-grown diamond?
A lab-grown diamond is a real diamond. It has exactly the same chemical composition, hardness, and optical properties as a natural diamond. The only difference is that it was not formed deep within the Earth over millions of years but was grown in a laboratory over the course of a few weeks. Even a professional jeweler cannot distinguish a lab-grown diamond from a natural one without specialized equipment.
What is a natural diamond?
A natural brilliant is a diamond that formed in nature billions of years ago and was subsequently cut into a brilliant shape. It is one of the most valuable gemstones in the world and remains a classic choice for engagement and wedding rings.
Main differences:

Which one shines more?
This is one of the most common questions. In fact, moissanite reflects more light than a diamond, resulting in a more pronounced rainbow effect. A diamond, on the other hand, has a more subdued and classic sparkle. It is a matter of taste.
Which one is more durable?
Both lab-grown and natural diamonds are the hardest materials in the world (10 on the Mohs scale). Moissanite, at 9.25, is only slightly softer and is perfectly suitable for everyday wear. All three stones will last for many years.
What is the price difference?
Moissanite is significantly more affordable. For the same budget, you can choose a much larger stone. A lab-grown diamond costs more than moissanite but significantly less than an equivalent natural diamond. Natural diamonds remain the most expensive.
Which one should you choose?
