How to Know If Your Diamond Is Real or a Simulant?
Ever wondered if your diamond is real? Here’s a simple way to find out — no tools needed!
Try the Newspaper or Line Test
Place your stone over a newspaper, a piece of text, or even a thin black line drawn on white paper.
If you can read the letters or see the line clearly, it’s probably a simulant like cubic zirconia (CZ).
If the text looks blurry or disappears, it’s likely a real diamond — real diamonds bend light so intensely that you can’t see straight through them!
This quick test is just for fun, but it’s a great way to learn about how diamonds interact with light — one of the secrets behind their brilliance.
✨ Fun fact: Diamonds have one of the highest refractive indexes of any gemstone, giving them their signature sparkle.
