How to Spot Fake or Dyed Granite

Not everything sold as "granite" is real granite. Some products are laminates, resin composites or tiles printed to look like stone, and some black granites are dyed to look darker and more uniform. Here is how to tell real granite from fakes before you buy.

What Real Granite Is Like

Appearance

Real granite has three-dimensional depth, visible crystals and natural variation. Patterns never repeat exactly.

Durability

It is very hard, scratch-resistant and heat-resistant.

Maintenance

Light granites need sealing; dark granites need little.

Where Does Granite Come From?

Real granite is quarried from natural rock, in Pakistan and around the world. FB Marble stocks Pakistani granites and imports from India, Brazil, Norway, Finland and Ukraine.

What Is Fake Granite?

Laminate printed with a granite pattern
Cultured granite — resin with stone dust and a gel coat
Printed tiles — ceramic or porcelain with a granite design
Dyed granite — real stone (often a lighter or cheaper rock) treated with dye to look black or uniform

How Can You Spot Fake Granite?

Check for Repeating Patterns

Step 1: Acetone test on black granite – fake granite — Step 1: Acetone test on black granite

Step 2: Scratch test – fake granite — Step 2: Scratch test

Printed products repeat their pattern. Real granite does not.

Look at the Edges

On laminate and tile, the edge often reveals a different core or a printed strip. Real granite looks the same through its thickness.

Feel the Temperature

Real granite feels cold to the touch.

Tap It

Real granite sounds solid. Laminate over board sounds hollow.

Scratch Test (on a sample)

Real granite resists scratching from a steel knife; laminate and resin scratch easily.

The Acetone Test for Dyed Black Granite

Rub a hidden corner with a white cloth dampened with acetone. If the cloth turns black, the stone has been dyed. Real black granite will leave the cloth clean.

Check the Cost

If the price is far below the market, be cautious.
