Moissanite vs Lab-Grown Diamond
Two modern, ethical stones — here's how they really differ.
Moissanite and lab-grown diamonds are the two most popular modern alternatives to mined diamonds. Both are beautiful and ethical, but they are different stones. Here is a clear, honest comparison to help you choose.
They are different materials
A lab-grown diamond is chemically a diamond, just grown in a lab instead of mined. Moissanite is a different mineral (silicon carbide) with its own optical properties. Both are lab-created, so neither requires mining.
Sparkle
Moissanite has more fire — those rainbow flashes — giving it a livelier, more colourful sparkle, especially at larger sizes. A lab diamond has the classic, more restrained diamond brilliance. It comes down to which look you prefer; see Moissanite Fire and Brilliance.
Price
| Moissanite | Lab Diamond | |
|---|---|---|
| Relative price | Lowest | Higher |
| Fire/sparkle | More fire | Classic |
| Hardness | Very hard | Hardest |
| Mined? | No | No |
Which is right for you?
Choose moissanite for the most size and sparkle per rupee and a lively look; choose a lab diamond if having a true diamond identity matters most. Both are durable enough for daily wear. More on value in Why Moissanite Is More Affordable.
