How to Tell the Difference Between Quartz and Corian Countertops

Quartz and Corian countertops are two of the most popular countertop materials on the market today. Both offer sleek, modern designs and have many similarities, which can make telling the difference between the two difficult. However, there are some key differences between quartz and Corian that can help you determine which material is right for your home.

What is Quartz?

Quartz countertops, also known as engineered stone, are made from ground natural quartz crystals combined with polymer resins and pigments. The quartz content typically makes up 90-94% of the material, while the rest consists of the binding polymers.

Here are some key facts about quartz:

  • Extremely durable and scratch resistant surface
  • Non-porous – resists stains
  • Available in wide range of colors and patterns
  • Requires minimal maintenance
  • Heat and scorch resistant
  • Not completely seamless – may have small seams between slabs
  • Resists most acids and chemicals
  • Made in slabs and cut/fabricated for installation

The durability and low maintenance of quartz make it an excellent choice for busy kitchens. The seamless look gives it a sleek, contemporary style. While more expensive than materials like laminate, quartz counters are an investment that can significantly increase home value.

What is Corian?

Corian is a solid surface material created by DuPont consisting of natural minerals and acrylic polymer. First introduced in 1967, Corian was one of the first “solid surface” countertop materials on the market.

Here are some key facts about Corian:

  • Made of natural minerals and acrylic
  • Available in wide range of colors/patterns
  • Can be fabricated seamlessly with inconspicuous seams
  • Scratch and stain resistant with proper care
  • Non-porous surface resists bacteria growth

  • Quartz is generally more expensive than Corian.
  • Corian used to be pricier but costs have come down in recent years.


  • Quartz requires very little maintenance aside from cleaning.
  • Corian needs regular upkeep to maintain its appearance.

As you can see, quartz tends to be the more durable and low maintenance option, while Corian offers more customization and can be repaired and refinished. Both materials have their pros and cons.

How to Tell the Difference Visually

Unless you know a countertop’s material already, it can be tricky to identify quartz from Corian at a glance. Here are a few tips to distinguish the two:

Check for visible seams

  • Quartz slabs will have a slightly noticeable seam where they meet. It may be small but can ususally be seen on close inspection.
  • Corian can be fabricated into seamless designs using inconspicuous seams. Check corners and edges for any visible seam lines.

Look closely at the surface

  • Quartz has a sparkly, granular appearance when viewed up close. You can see the flecks of quartz crystals.
  • Corian has a more consistent, smooth and even solid surface with no sparkling grains.

Examine edges and thickness

  • Quartz slabs are usually 1.25 inches thick. Edges are cut straight.
  • Corian can be customized into thinner sheets around 0.5 inches thick. Edges can be curved and shaped.

Consider sheen and gloss level

  • Quartz has a brighter sheen and reflectivity from its resin binders.
  • Corian tends to have a flatter, matte finish unless polished to a gloss.

See if it can be scratched

  • Quartz is extremely hard and scratch resistant. Attempting to scratch it with a knife should leave no mark.
  • Corian is softer and prone to scratching. Try lightly scratching a small hidden spot. Corian will show light abrasions.

With some careful examination, you should be able to spot key differences between quartz and Corian. When in doubt, asking a homeowner or checking installation paperwork can provide a definitive answer.
