Does moissanite fade or yellow?
**NOT**. High quality moissanite has a stable colour and will not yellow or fade over time or light. However, low quality moissanite may have a light yellow/grey tint on its own, it is recommended to choose **D-F colour (colourless grade)** when purchasing.
How can I tell a moissanite from a diamond?
- **Diamond detector pen (thermal conductivity meter)**: moissanite also passes (because it conducts heat).
- **Magnifying glass observation**: moissanite has birefringence, diamond does not.
- **Comparison of fire colours**: moissanite has more intense fire colours, especially in bright light.
