Colour
Different types of granite are characterized by different colors. It depends on where they came from. If there is any doubt in the authenticity – find out where it came from.
All large deposits are known, and each of them gives a stone a characteristic pattern and color, and you can easily find this information and compare the sample you are offered with the standard.
Uneven coloring
Granite has a granular structure and uneven color. Combination of various colors is perfectly normal for this rock.
However, if in such a combination of two or three primary colors there is a single odd impurity, it means that the structure includes some different rock.
The inclusions are different from the natural fragments, and the fragment may eventually fall out of the final product.
Chips and cracks
Chips are visible to the naked eye.
Natural cracks appear from the displacement of tectonic plates while technical cracks appear due to inaccurate transportation or during the process of extraction.
Large cracks are quite noticeable. To detect smaller ones, moisten the surface of the plate and wait for drying: the cracks will become more contrasting on the background of the plate.
Microcracks cannot be easily noticed. Just bear in mind: the granite with larger grains is more prone to the appearance of microcracks than the fine-grained. type.
Authenticity
Be careful when buying finished products from granite: they can be cast from granite chips and binder.
It is better to order final products at factories since the casting with subsequent processing would minimize all the savings of using granite chips.
However, the safest guarantee will still be ordering from a reliable manufacturer.
In a reliable workshop you can always check the certificates listing the characteristics of the materials used. Comparing them with widely available reference data, you can always check the authenticity of granite yourself!
