You may experience uncertainty when purchasing a diamond, particularly an engagement diamond. This is not unjustified with the increased incidence of treated diamonds, synthetic diamonds and diamond simulants, no to mention incorrectly certified or graded diamonds
Some Quick Tips
Buy from a reputable jeweller. A reputable jeweller sells with genuine diamond grading certificates.
 
Buy with a diamond grading certificate from an independent and recognised diamond grading laboratory. This ensures you have a natural, untreated diamond that has been graded accurately.
 
Note that a valuation or appraisal is NOT a certificate.
 
Read the certificate carefully to ensure that you make an informed decision
 
Price comparison is only possible if you are comparing certified diamonds. Diamond Certification allows you to compare prices without unknowingly sacrificing quality or natural origin.
 
Be cautious of sales which appear to be genuine but are nothing more than a large discount off an inflated price. If it seems to good to be true, it probably is.
 
Be cautious of internet retailers offering a huge selection of diamonds. Often many are not available - this is a classic baiting scam.
 
Buy a diamond that is cold laser inscribed. This identifies the diamond and ensures you get the one described by the diamond's certificate.
 
Do not buy your diamond overseas, buy locally. This ensures you have recourse if anything is wrong.
 
Diamonds are priced the same way worldwide -there are no cheap diamonds, only lower quality.
 
Never buy a diamond without seeing it first. The internet has become the perfect marketplace for selling the leftovers, which are impossible to sell for the asking price through traditional diamond channels.
 
Do not buy a diamond with a bogus or in-house diamond certificate. If you are unsure, do your research on the laboratory that issued the report. Examples of in-house certificates are manufacturer reports and appraisals generated by the seller.
 
The seller's valuation or certificate it is not independent and may be overstated. Genuine diamond grading laboratories do not sell diamonds nor do the employees have any interests in the jewel lery trade, as this represents a significant conflict of interest.
 
Do not accept unknown diamond certificates or photocopies of the original diamond certificate.
 
Never shop based on price alone - this generally results in a lower quality, not a better deal. Generally speaking, you will get what you pay for.


Knowledge is key to any decision. Certification is vitally important to ensure you make an informed diamond purchase.
