3 simple tips to ensure the authenticity of the stone:
The authentic fossils
The visible presence of fossilized crinoids gives Blue Limestone Hainaut its incomparable character and charm and is proof of the authenticity of this local stone, which is far more resistant than any other stones of similar appearance. The Asian dolomitic rocks have no fossils, but they do have oolites that oxidize over time. Look closely, touch and compare. The authenticity of formerly living organisms makes all the difference.
Tip: Soak the stone in water. If it shows rings or brownish zones of a different shade, it is dolomitic stone, most of the time from Asia.
