How do we know if a diamond is real?

You don't need to be an expert to determine if a diamond is real. However, if you suspect that the diamond you have might be fake, you can try the following methods. Remember, the most reliable way to verify a diamond's authenticity is to seek help from a professional jeweler. Here are some simple tests:

Newspaper Test:

Place your diamond on a newspaper. If you can read the letters through the stone, it is likely a fake diamond made of glass or quartz. Real diamonds have a high refractive index, which bends light and makes the letters difficult to read.

Weight Test:

If you are familiar with carat or gram measurements, you can use the weight test. Fake diamonds are usually heavier than real diamonds.

UV Light Test:

Using a UV light or black light in a dark room, you can test your diamond. Real diamonds typically emit a blue fluorescent light. However, if there is no blue light, it might indicate a higher quality diamond. If you see green, yellow, or gray fluorescence, the diamond might be fake.

Rainbow Test:

If your diamond's sparkle shows many rainbow reflections, it could be fake. Real diamonds reflect shades of gray.

Flaw Test:

Diamonds usually have small flaws like carbon traces or slight deviations. You can check these flaws with a magnifying glass. If your stone has no flaws, it might be either a very rare diamond or a fake one.

The Most Important Test:

The most reliable way to determine if your diamond is real is to consult a professional jeweler.
