How to Spot a Quality Diamond: 5 Red Flags to Avoid

Choosing the perfect diamond can feel overwhelming, especially with so many options and sources available today. While sparkle and size often steal the spotlight, the real value of a diamond lies in its quality. At Freya Jewellery, we want you to buy with confidence. Here are five red flags to watch for when choosing your diamond.

1. No Certification

A reputable diamond should always come with an independent grading report from a recognised institution, such as GIA (Gemological Institute of America) or IGI. If a seller offers a diamond without certification—or provides one from an unknown lab—it’s a clear warning sign.

At Freya Jewellery, we only sell certified diamonds with documentation you can trust.

2. Cloudy Appearance

A diamond should be bright and brilliant. If it appears dull, milky, or cloudy—even under standard lighting—it may have inclusions or poor clarity. Ask to view the diamond under magnification and different light settings. Trust your eyes as much as the grading report.

3. Vague or Incomplete Descriptions

Terms like “high quality” or “excellent sparkle” mean nothing without detailed specifications. A trustworthy jewellery will always provide clarity, colour, cut, and carat details, as well as the diamond’s grading certificate.

If you feel like you're getting more sales pitch than information, it’s time to walk away.

4. Unusually Low Prices

If a diamond seems too good to be true, it probably is. Bargain prices can indicate lab-grown stones being misrepresented as natural, poor quality cuts, or unethical sourcing. Always compare prices across reputable sellers to understand fair market value.

5. No Return or Warranty Policy

Reputable jewellers stand behind their products. Be wary of anyone who won’t offer returns, exchanges, or warranties. You should be able to examine your diamond in peace—without pressure—and return it if it doesn’t meet expectations.
