How can I tell if a diamond is real at home?

You can check for reflections, fog test, and scratch test — but none of these methods are fully reliable. For 100% certainty, use a gemological certificate from IGI or GIA.

What’s the most accurate way to know if a diamond is real?

The most reliable method is checking a gemological certificate issued by a trusted lab like GIA or IGI. The certificate confirms if it’s natural, lab-grown, moissanite, or synthetic.

Are cheap diamonds real?

Sometimes yes — for example, lab-grown diamonds can cost much less than natural ones. But be cautious: if the price seems too good to be true, check the certificate to avoid scams.

“I paid $700 instead of $2,800 — and got the exact same pair”

I uploaded a photo of diamond earrings I saw in a store. Within 24 hours, I got three real offers from verified suppliers — and one of them offered the exact same pair for less than half the price.
I bought it. I wear them daily.

Why it’s smart to compare before buying diamond jewelry?

Same diamond, very different prices

The exact same diamond — same carat, color, and clarity — can cost twice as much depending on where you buy it.
Without comparison, you’ll never know.

Not all “deals” are real

Many “discounted” prices are still far above market value.
Seeing offers side-by-side helps you avoid overpaying.

Manufacturers vs. stores

Most jewelry stores buy diamonds from the same suppliers — and add large margins.
Comparing prices means seeing the true value before the branding.
