Moissanite and lab grown diamonds are excellent alternatives to mined stones, providing a similar look but without the ethical concerns. Those in the market for luxury jewelry might question how these substitutes compare and which one is superior.
Â
Explore the differences between lab grown diamonds and moissanite and find out why our lab created gems at Grown Brilliance excel in quality, brilliance and durability, making them the perfect choice for your jewelry.

What is a Lab Grown Diamond?
Lab grown diamonds are real diamonds created in controlled laboratory environments using responsibly sourced raw materials like carbon and methane gas. Â
Â
Growers use High-Pressure High-Temperature (HPHT) or Chemical Vapor Deposition (CVD) to mimic the natural conditions under which diamonds develop, exposing a carbon seed to extreme heat and pressure until it crystallizes into the gemstone. The result is a real diamond with the same structure and composition as its natural counterpart.Â
Â
Mined diamonds and lab grown diamonds share the same purity and brilliance, but grown stones provide a more responsible alternative without compromising on quality. Unlike moissanite, which just imitates the appearance of diamonds, lab grown diamonds are real stones, offering unmatched sparkle and genuine authenticity in every aspect.

What is Moissanite?
Made of silicon carbide, moissanite is a naturally occurring mineral. This gemstone is remarkable for its brilliance and fire, characteristics that closely resemble those of natural diamonds, making it a popular alternative.Â
Â
Natural moissanite is incredibly rare, so most of the moissanite on the market today is created in dedicated facilities. This process involves using high temperatures to vaporize silicon carbide, which then recrystallizes to form man-made moissanite stones. The result is a lustrous gem that looks similar to diamonds and can be used in jewelry like rings, necklaces and bracelets.Â
Differences Between Moissanite and Lab Grown Diamonds
When selecting a stone for fine jewelry, evaluating the different characteristics of moissanite and lab grown diamonds can assist you in making an informed choice.
Feature | Moissanite Gemstones | Lab Diamonds |
---|---|---|
Composition | Composed of silicon carbide, which forms a complex crystal structure that offers exceptional hardness. | Made from carbon atoms arranged in a diamond cubic crystal structure, identical natural diamonds ensuring ultimate durability and shine. |
Hardness (Mohs Scale) | Very hard at 9.25, resistant to scratches. | Score of 10, the hardest mineral, ideal for everyday wear. |
Brilliance | High brilliance can sometimes appear more sparkly than diamonds, which can appear manufactured. | Matches the brilliance of natural diamonds, providing authentic sparkle. |
Fire | High fire, shows colorful flashes of light, which can be overwhelming. | Lower dispersion of light mirrors the subtle and sophisticated fire of natural diamonds. |
Authenticity | A popular diamond alternative but not carbon-based, often used for its unique properties. | Genuine diamonds with all the properties of mined stones, preferred for authenticity in high-end jewelry like lab grown diamond rings. |
Price | Generally affordable, appeals to budget-conscious buyers. | Can be priced higher than moissanite but offers a true diamond experience at 50% to 60% of the cost of mined diamonds. |
