How to Check if your Quartz Slab is Real or Fake? (Aviod Fakes)

Quartz slab is a highly popular material for kitchens, bathrooms, wardrobes, and commercial interiors because of its durability, modern finish, and low maintenance. However, rising demand has led to the sale of fake or low-grade materials that are often marketed as genuine quartz slab, as factory production allows manufacturers to alter composition and reduce quality.

Therefore, homeowners, architects, and contractors must know how to verify quartz slab authenticity before making a purchase.

In this article, we explain how to identify real quartz slabs and differentiate them from fake or low-grade alternatives available in the market. We also cover practical inspection methods, key quality indicators, and buyer tips to help you make an informed purchase decision.

Fake Quartz Slabs in the Market

Today, many stone yards are filled with slabs that look like quartz slabs but are actually something else. Since actual quartz slabs are costly, some sellers try to fool buyers by showing cheaper stones in its place. These slabs may look similar, but they are not the same in terms of quality, strength, or lifespan.

In most cases, sellers use ceramic slabs, nano marble, vitrified slabs, or low-grade engineered stone and sell them as quartz slabs.

These materials may look glossy at first, but they chip easily, absorb stains, crack under heat, and lose shine over time. Real quartz slabs, on the other hand, is dense, strong, non-porous, and made to last for years without trouble.

This is how many buyers get fooled! So, you should always ask for proper material details, brand name, and warranty before buying. 

How to Check If Quartz Slab Is Original or Fake?

Are you confused and couldn’t pick between the fake and the original quartz? Well, when visiting local stone yards in Pune, you can use these practical checks to identify real quartz:

1. Size of the Slab – The First Thing You Should Always Check

One of the easiest ways to spot fake quartz slab is by checking the slab size. If the slab size is 800 × 2400 mm or 800 × 3200 mm, there is a very high chance that the material is not original quartz slab. Sellers use these slabs for alternative materials because they are easier and cheaper to manufacture.

Original quartz slabs are produced only in large formats, typically:

• 1400 × 3000 mm
• 1600 × 3200 mm

Smaller slab sizes are commonly used for alternative materials because they are cheaper to produce and easier to transport. So if someone claims it’s ‘premium quartz slab’ but offers it only in small sizes, that’s your first warning sign.

Additionally, large-format quartz slabs are manufactured using high-pressure vibro-compaction technology, which requires specialized machinery and quality raw materials. Smaller slabs often indicate simplified production methods that cannot achieve the same structural strength or consistency. Larger slabs also reduce joint lines in countertops, which improves both durability and aesthetics in finished installations.

Slab Size Authenticity Check

2. Polish Quality – Shine vs Over-Shine

Many buyers usually believe that a shiny surface and better quality go hand in hand. But in reality, this is the opposite when it comes to quartz slabs. Fake quartz slabs usually has a mirror-like reflective finish that comes from a coating applied on top. It does not come from the material itself.

And, on the other hand, Original quartz slabs has a clean and elegant finish. It reflects light softly and does not act like a mirror.

The shine of real quartz slabs feels natural and premium, not glossy or artificial.

Another important check is to observe the surface under different lighting conditions. Artificial coatings often create uneven reflections, streaks, or cloudy patches when viewed from different angles. Genuine quartz slab maintains consistent polish across the slab because the shine is achieved through mechanical polishing rather than chemical surface coatings. This consistency improves scratch resistance and long-term appearance retention.

Polish Quality Comparison

3. Quartz Chips – Look Closely for Natural Texture

One of the most reliable ways to identify real quartz slab is by closely examining the surface. Original quartz slabs are made using natural quartz crystals, which means you will see:

• Tiny quartz chips are embedded in the surface
• Sometimes even larger chips, depending on the design
• These chips add depth and texture to the slab.

In fake quartz slabs or artificial materials, chips are usually missing. Even if chips appear to be present, in 99% of cases, they are either printed or extremely minimal. So, run your eyes and fingers over the surface, as real quartz slabs has depth and texture.

You can also examine the slab edge or cross-section for confirmation. In genuine quartz slabs, the chips and pigments continue throughout the slab thickness, showing uniform composition. In contrast, printed or coated materials usually reveal a different inner structure when viewed from the side, indicating surface-only design. This simple edge inspection is one of the most trusted verification methods used by industry professionals.

Quartz Chip & Texture Verification

4. Pattern Check –  ‘Too Perfect’ can be Fake

This might sound strange, but it’s true. If the slab pattern looks exactly like natural marble, with dramatic veins and a highly detailed design, it is most likely not real quartz slab.

Quartz slabs do not naturally replicate marble patterns. Real quartz designs:

• Are simple and balanced
• Look slightly handmade
• Have a low-resolution, natural appearance

On the other hand, fake materials often use high-definition printed marble designs because they are visually attractive and easier to sell. Ironically, when quartz slabs looks ‘too beautiful,’ it is often a warning sign.

Another useful method is to compare multiple slabs from the same batch. Genuine quartz slabs usually show slight variation in vein flow and pattern placement, whereas printed slabs often display identical or repeated patterns. Repetition in design is a strong indicator of digital printing or surface lamination rather than engineered quartz manufacturing.

Pattern Authenticity Test

5. Quartz Thickness – A Small Detail with a Big Impact

Thickness is another major giveaway. It plays a major role in quality and durability.

• Fake quartz is commonly 15 mm thick
• Original quartz is typically 20 mm or 30 mm thick

Thinner slabs are cheaper to manufacture and easier to handle, but they compromise strength and durability. If a seller avoids discussing thickness or insists 15 mm is ‘standard,’ be cautious.

Moreover, thicker quartz slabs provide better load-bearing capacity, especially for kitchen countertops, island tops, and commercial installations. They also reduce the risk of cracks during fabrication, transportation, and installation. High-quality quartz slabs manufacturers maintain strict thickness tolerances, ensuring uniform structural performance across the slab.

Thickness Quality Check

6. Documentation – Never Skip This Step

Buyers must always ask for proper documentation before purchasing.

This includes:

• A valid invoice
• Product certification
• Brand details

Check that the brand name and HSN code are clearly mentioned on the invoice. Genuine quartz slab suppliers are transparent with documentation, while fake products often come with vague or incomplete paperwork.

You can also request technical data sheets and warranty details from the supplier. Authentic quartz slab brands usually provide information about resin content, quartz percentage, stain resistance, and heat tolerance. These documents confirm product authenticity and help buyers understand long-term performance and maintenance requirements.

Documentation & Certification Verification

7. Packaging – How the Slab Is Delivered Tells a Back Story

Packaging is another important clue that buyers often overlook. It tells you a lot about the product’s authenticity.

Original Quartz Slabs:

• Come with a protective plastic film on the surface
• Are not packed in cardboard or wooden boxes

Fake Quartz Slabs:

• Are often packed in cardboard boxes
• Usually lack a protective surface film

Manufacturers of genuine quartz protect their slabs carefully because of their value. Premium materials are handled and transported with care, and their packaging reflects that.

Additionally, original quartz slabs usually carry manufacturer branding, batch numbers, and barcode labels on the protective film or slab edges. These identifiers help trace product origin and quality control records. Absence of branding or traceability markings can often indicate unverified or duplicate materials in the market.
