A unique material with a unique mark

If you have doubts about your bluestone’s origin, you can always request a certificate of origin from the distributor, who will then contact Carrières du Hainaut to obtain it. Because we mark and certify all our products with a unique number and stamp, the certificate means your bluestone is authentic.

How to recognize Belgian bluestone

In addition to the certificate, there are other ways to recognize authentic Bluestone from Hainaut. The presence of crinoids, for example, is telling. Crinoids are clearly recognizable as fossil remains of marine fauna and flora. They are not to be confused with the white spots typically seen in similar types of stone from Asia. Those spots arise in dolomite-rich stones and are called oolites. Through oxidation, these oolites can change into rusty stains.

You can also put your bluestone to the test by immersing it in water. If circles start to form and the surface displays different shades of (rust-like) brown, then you are dealing with dolomite rock, which usually comes from Asia.

Finally, it is also important to make sure you are looking at the real deal and not ceramic counterfeit. Turn the stone over or try to take out a loose piece, and pay careful attention to the material inside. Bluestone is, of course, a solid material, while ceramic counterfeit tiles usually have a printed surface. Therefore, take a closer look at the stone, have a feel and compare. The authenticity of a living material makes a world of difference in interiors and gardens.
