When it comes to choosing a gemstone for an engagement ring or a special piece of jewelry, many people are torn between moissanite and lab grown diamonds. Both options have their unique characteristics, advantages, and disadvantages. In this article, we’ll delve into the world of moissanite and lab grown diamonds, exploring their key differences, features, and cons to help you make an informed decision.
Moissanite vs Lab Grown Diamonds: Key Differences

The main differences between moissanite and lab grown diamonds lie in their composition, brilliance, durability, and price. Moissanite, made from silicon carbide, stands out for its fiery sparkle and high refractive index, creating a bold, colorful brilliance.
Lab grown diamonds, composed of pure carbon like natural diamonds, offer a refined, white-light sparkle with exceptional hardness. While moissanite scores 9.25 on the Mohs scale and lab grown diamonds a perfect 10, both are durable enough for everyday wear, making them excellent choices for fine jewelry.
