Unless you have experience with jewelry, it's difficult to know.
If you do have experience, usually, you try to find reasons to believe it is not a diamond.
At first glance, does it look like it has rainbow colors coming out of it? If not, and it's just white light, it is probably a CZ or diamond look-alike.
To prove it to be non-diamond, look at it under a loupe (10x magnification) and search for:
- Scratches. A diamond can't be scratched, though it can be broken and can have natural crystal surfaces on it. If it looks "worn," it's most likely not a diamond.
- Rounded Facet Junctions. Where two facets meet, it will be "polished" or rounded. A diamond will have "sharp" junctions.
- Glassy or "watery" girdle. A diamond will have a "soft" looking girdle, little tiny facets all the way around, or a flat polished girdle. A CZ's polished girdle will look watery.
- Doubling (ghostlike images of the same facet doubled) when looking into the diamond.
To prove it to be a diamond, look for inclusions. If it has any mineral inclusions, it's most likely a diamond.
Breathe on the diamond. If the diamond fogs up, it is definitely a fake. If not, you have a real diamond in your hands.
It could be. It's almost certainly not, but it could be.
