Lab Grown Diamond vs Moissanite
Lab grown diamonds and moissanite are both brilliant lab created stones at different prices. Compare hardness, fire, color and value to choose the right one.
What Is a Lab Grown Diamond
A lab grown diamond is a real diamond created in a laboratory using HPHT or CVD methods. It has the same carbon crystal structure, hardness and brilliance as a mined diamond, and it is graded with the same 4Cs. Lab grown diamonds cost 30-50% less than natural diamonds but remain the premium choice among lab created stones.
What Is Moissanite
Moissanite is a silicon carbide gemstone, originally discovered in a meteorite and now produced in labs. It is nearly as hard as diamond at 9.25 Mohs, and it has higher fire than diamond, producing a rainbow-like sparkle. Moissanite costs a fraction of the price of a lab grown diamond, making large stones very affordable.
| Feature | Lab Grown Diamond | Moissanite |
|---|---|---|
| Hardness | 10 Mohs | 9.25 Mohs |
| Fire | Classic white sparkle | Stronger rainbow fire |
| Price | 30-50% below natural | Fraction of diamond price |
| Best for | Traditional diamond look | Maximum sparkle on budget |
