Distinguishing between Silestone and granite countertops can be challenging, especially if you are not familiar with their characteristics. Here are some ways to help you identify whether your countertop is made of Silestone or granite:
Appearance: Observe the overall appearance of the countertop. Silestone is an engineered quartz product, meaning it is made of natural quartz crystals mixed with resin and other materials. As a result, Silestone often has a more consistent and uniform appearance with fewer natural variations in color and pattern compared to granite. Granite, on the other hand, is a natural stone and typically exhibits more prominent veining, color variations, and natural patterns.
Texture: Run your hand along the surface of the countertop. Silestone generally has a smoother and more uniform texture due to its engineered nature. Granite, being a natural stone, can have a slightly rougher texture and may contain natural pits and fissures.
Temperature: Touch the surface of the countertop with your hand. Silestone tends to feel warmer to the touch than granite. Granite has excellent heat resistance, and its natural stone properties make it feel cooler at room temperature.
Weight: While not always easy to determine without experience, granite countertops are typically heavier than Silestone countertops due to the density of the natural stone.
Appearance of Seams: If you can locate the seams where two pieces of countertop are joined, it might give you a clue. Silestone's uniform appearance often means less visible seams, while granite may have more noticeable seams due to its natural patterns.
Color and Pattern: Pay attention to the color and pattern of the countertop. Silestone offers a wide range of colors, including solid colors and patterns that mimic the look of natural stone. Granite, being a natural material, will have a more varied color and pattern selection.
Acid Test (For Experts Only): This method is not recommended unless you have consulted a professional and know the potential consequences. Silestone is highly resistant to acids due to its engineered composition, while granite may be affected by acids and etch if exposed to them. An inconspicuous spot can be tested with a mild acid (like vinegar) and monitored for a reaction.
If you are still uncertain about the material, the best way to identify your countertop is to check any documentation or paperwork from the previous owner, builder, or installer. You can also consider consulting with a professional stone fabricator or installer who can assess the material and provide a definitive answer.
