Decoding Basalt: Tips to Identify Authentic Basalt Stones

Basalt is a volcanic rock that has been used for centuries in construction, sculptures, and decorative items. However, due to its increasing popularity, there are many imitations of the authentic stone available in the market. Hence, it is essential to know how to identify genuine basalt stones before making a purchase. Here are some tips to help you decode basalt.

1. Look for pores: Basalt stones have a porous surface due to the presence of air pockets created during the cooling process of volcanic lava. These pores are visible under a magnifying glass and are an excellent indicator of the authenticity of the stone.

2. Check for weight: Basalt is a dense rock and is heavier than most other stones of the same size. Pick up the stone and feel its weight. If it feels lighter than it should be, it may not be genuine basalt.

3. Examine the texture: Basalt has a fine-grained texture that is smooth to the touch. It should not have any rough or jagged edges. If the stone has a coarse texture or is rough, it may be an imitation.

4. Look for uniformity: Authentic basalt stones have a consistent color and texture throughout the surface. If you notice any variations in color or texture, it may be an indication of an imitation.

5. Conduct a water test: Basalt is an igneous rock and is non-porous. It does not absorb water. If the stone absorbs water, it is not authentic basalt.

6. Seek expert advice: If you are unsure about the authenticity of a basalt stone, seek the advice of an expert. They can help you identify genuine stones and distinguish them from imitations.

By following these tips, you can confidently identify authentic basalt stones and avoid purchasing imitations. Remember to always do your research and purchase from reputable suppliers.
