How to buy a diamond online
After determining your budget and the criteria of weight and quality of the ideal diamond for you, there are still a few questions before you can take the step of buying from an online diamond dealer. On the internet, you will find a diamond made to measure and at the best quality/price ratio. But nothing is more delicate than buying a diamond online. How to buy your diamond with confidence?
Get advice from a diamond dealer
The Internet offers many advantages at your fingertips. You can read numerous guides on diamonds with complete peace of mind and browse through several diamond catalogs with prices displayed in complete transparency. But to help you make a vast choice, nothing beats the precious advice of an expert. By email or by phone, talking to a diamond dealer is a real plus to refine your choice and make the most relevant decision. At i-diamants, founded and managed by a family of diamond dealers present in Antwerp for four generations, we also offer you a selection of diamonds carefully selected, our core business.
Demand a certified and engraved diamond by GIA, HRD or IGI
It is essential to buy a natural diamond certified by one of the 3 unique gemmological laboratories recognized worldwide: the GIA, the HRD or the IGI. On the certificate issued by these laboratories, are indicated all the criteria indicated above (weight in carat, color, purity, quality of cut...). Each diamond is unique and has a certification number. This number can also be inscribed on the diamond's roundel, which attests to the good correspondence stone/certificate.
