When you're taking a look at a diamond through a loupe, a real stone is going to have sharp edges, and a fake stone will have rounded edges.
If the metal used for detting diamond is gold plated or silver, chances are it's not a diamond because Most diamonds are mounted in gold or set in platinum.
If the setting of a diamond looks like it's of poor quality, that probably means it's not going to be a real diamond either.
Rub a sandpaper with your stone.If it's a diamond, it will remain perfect, if it's a cubic zirconium, it will scratch it up.
Breathe hot air on your stone.A fake diamond will fog up for a short period of time whereas a real diamond will not because it won't retain the heat.
Diamonds reflect light uniquely.A fake diamond will have rainbow colors that you can see inside the diamond whereas the real one sparkles grey and white colors inside the stone.
