Moissanite and CVD diamond are fundamentally different in terms of their chemical composition, physical properties, and production methods. Moissanite is a silicon carbide and is considered a diamond simulant, while CVD diamond is a real diamond created through a chemical vapor deposition process.
Chemical Composition and Origin:
- Moissanite is composed of silicon carbide (SiC), a compound that is extremely rare in nature. Most moissanite available today is synthetic, created in laboratories to mimic the appearance of diamonds. Despite its diamond-like appearance, moissanite has a different chemical structure and different optical properties. It is double-refractive, meaning it splits light into two rays as it passes through, unlike diamonds which are single-refractive.
- CVD Diamond, on the other hand, is a real diamond. It is formed through a process called chemical vapor deposition, where carbon-rich gases are broken down to deposit carbon atoms on a substrate, forming a diamond layer. This process results in a diamond that has the same chemical composition (pure carbon) and crystal structure as natural diamonds.
Physical Properties and Appearance:
- Moissanite exhibits a different kind of brilliance compared to diamonds. It often has a more colorful sparkle due to its double refraction. While it is durable (with a hardness of 9.5 on the Mohs scale), it is not as hard as diamonds (which have a hardness of 10). Moissanite can sometimes be confused with diamonds due to its heat conductivity properties, which are similar to those of diamonds.
- CVD Diamond has the same optical properties, hardness, and durability as natural diamonds. It is indistinguishable from natural diamonds without specialized equipment and is considered a real gem in terms of quality, value, and price.
Production Methods:
- Moissanite is synthesized in a laboratory, typically using high-temperature furnaces to crystallize silicon carbide. The process is designed to produce a gemstone that closely resembles diamonds but at a lower cost.
- CVD Diamond is also grown in a laboratory but through a very different process. The CVD method involves a vacuum chamber where gases are ionized to release carbon atoms that then crystallize into diamond. This process can take about two weeks to form a diamond, much faster than the geological time scales required for natural diamond formation.
In summary, while both moissanite and CVD diamond are lab-created, moissanite is a diamond simulant with different chemical and physical properties, whereas CVD diamond is a genuine diamond with the same properties as natural diamonds.
