How does moissanite compare to diamond?
- Very similar hardness (9.25+ vs 10), but lower value makes moissanite a bit less brittle, less prone to chipping and more durable overall
- Higher refractive index (2.65–2.69 vs 2.42), which gives moissanite more brilliance and sparkle compared to diamonds
- Lower Abbe number. It means that moissanite tends to disperse light into colors more than diamond, giving moissanite more fiery or rainbow colors
- Usually lab-produced, so much more ethical in general, and much higher clarity on average
- It’s waaay cheaper
So for anyone going for a diamond ring, I suggest trying moissanite instead. The only thing that diamond has going for it in this comparison is just decades-long PR. It’s not even a fun gem chemistry-wise, it’s just carbon. Moissanite, on the other hand, is SiC :)
Thanks, that's interesting to know. Btw, do you mind sharing what felt oddly bright about moissanite specifically? Was it too noticeable/distracting in your periphery vision? Haven't heard someone comment that about them before.
