Blue stone has been one of the most popular materials in Belgian construction for centuries. But when choosing your patio tiles<\/a> or sills<\/a> You'll quickly come across two types: Belgian and Vietnamese blue stone. The price difference is significant, but what exactly do you get for your money? As a family-owned business with more than 100 Years of Experience with Natural Stone<\/a> We'll lay out the facts clearly.<\/p>\n\n\n\n

What is the difference between Belgian and Vietnamese blue stone?<\/h2>\n\n\n\n

The main difference lies in the geological composition. Belgian blue stone (also known as \u2018petit granit\u2019) is a compact, non-porous limestone that formed 345 million years ago in the subsurface of our Hainaut region. Asian varieties have a different mineral composition with a higher dolomite content (calcium and magnesium) and are therefore less suited to our climate.<\/p>\n\n\n\n

How can you tell the difference? Crinoids vs. oolites<\/h3>\n\n\n\n

You can recognize Belgian blue stone by its crinoids<\/strong>: fossilized sea lilies that appear as small white dots or lines. These are authentic indicators of its Belgian origin. Vietnamese stone, on the other hand, contains o\u00f6lietes<\/strong>: round, whitish calcium carbonate pellets that can oxidize over time and form brown spots.<\/p>\n\n\n\n

Tip:<\/strong> Soak a small piece of stone in water for a long time. Do rings appear? If so, it\u2019s not Belgian bluestone.<\/p>\n\n\n\n
