When rough diamonds are mined from various parts of the world—mainly Africa, Australia, and Canada—they undergo sorting and quality assessment by experts before being sent for cutting and polishing in different countries. One term you may have heard of is the "Belgian Diamond", which often raises a lot of questions:
What exactly is a Belgian diamond?
Is it real?
Is it good quality?
And how much does it cost?
This article will answer all your questions.
Is a Belgian Diamond Good?
Why choose Belgian diamonds?
Belgian diamonds refer to rough diamonds that have been cut and polished in Belgium. Around 30 years ago, Belgium was globally recognized as one of the top countries for expert diamond cutting. As a result, "Belgium Cut" diamonds became known for their exceptional craftsmanship and quickly gained high demand in the market.
In Thailand, most real diamonds over 30 points (0.30 carats) that come with certification from GIA (Gemological Institute of America) or HRD (Hoge Raad voor Diamant) are generally considered Belgian diamonds. However, owning a Belgian diamond doesn’t automatically guarantee high quality, since not all diamonds cut in Belgium are equal. That’s why it’s important to learn about Triple Excellent (3EX) diamonds, which refer to superior cut, polish, and symmetry—key indicators of a well-cut diamond.
Quick Note: What Is a Russian Cut Diamond?
You may have heard the term "Russian Cut Diamond" and wondered how it differs from Belgian Cut. The concept is simple: if Belgian Cut diamonds are cut in Belgium, then Russian Cut diamonds are cut in Russia. The difference between the two is minimal—mostly related to precision in angles and cutting sharpness. Without professional training, most people wouldn’t be able to tell the difference.
How Much Does a Belgian Diamond Cost?
The price of a Belgian diamond depends on multiple factors—not just where it was cut, but also the 4Cs:
A Belgian Cut diamond with Triple Excellent (3EX) grading, D Color (the highest, most colorless grade), and very few inclusions, can be extremely valuable—easily reaching millions of baht.
Buying a high-quality diamond is more than just a personal treasure—it’s also a smart investment. Beautiful diamonds are easy to sell or pawn at high value, and prices are projected to rise steadily in the future, making them a reliable long-term asset.
Conclusion
So, what is a Belgian Cut diamond?
Yes, it’s real, natural, and high quality, provided it meets the criteria of cut, color, clarity, and carat. The difference between Belgian Cut and Russian Cut is minimal and mostly technical.
