Have you run your hand across a granite countertop and felt tiny dips or holes? Then you have found what the trade calls pits. Pits in granite countertops are common, and in almost every case they are completely normal. In fact, they are part of what makes natural stone truly natural. So before you worry, here is a clear, no-jargon look at what pits are, why they happen, and whether they matter — from Maranatha Granite in Birmingham, AL.
What Are Pits in Granite Countertops?
A pit is a small, natural indentation on the surface of the stone. Think of it as a tiny gap between the mineral crystals that make up granite. Most pits are smaller than a pinhead. Because granite is a mix of many minerals, these little gaps form naturally as the stone cools deep underground. As a result, you will spot them on many slabs — especially the coarser, more speckled ones.
Are Pits in Granite Normal?
Yes. Pits are completely normal in natural granite. They are not a sign of poor quality, and they are not a manufacturing mistake. Instead, they are simply how the stone formed over millions of years. In fact, for many granite colors, a slab with zero pits would be the unusual one.
What Causes Pits in Granite?
Granite is a blend of minerals — quartz, feldspar, mica, and more. During formation, these minerals crystallize at different rates. So small gaps naturally appear where the crystals meet. Coarse-grained, heavily speckled granites tend to show more pits. Finer-grained stones show fewer. Either way, the pits are part of the natural structure, not damage.
Are Pits a Defect?
No. Pits are cosmetic, not structural. They do not weaken the countertop, and they do not spread or get worse over time. Your granite is just as durable with them as without. For that reason, the natural stone industry does not treat pitting as a defect.
Pits vs. Cracks vs. Fissures
These three often get confused, so here is the quick difference:
- Pits — tiny surface gaps between crystals. Completely normal.
- Fissures — natural hairline lines that follow the mineral pattern. Also normal, and not the same as a crack.
- Cracks — actual damage, usually from impact or stress. This is the only one worth real concern.
If you are unsure which one you are looking at, a fabricator can tell you in seconds.
How to Care for a Pitted Granite Surface
Good news: pitted granite needs no special care. First, clean it like any granite — mild dish soap and water, no harsh chemicals. Next, keep it sealed so liquids do not settle into the pits. Finally, if a pit ever bothers you, a fabricator can fill it with a color-matched resin. For the full routine, see our granite maintenance guide, which follows Natural Stone Institute best practices.
So, Should You Worry About Pits?
In short, no. Pits are a normal, cosmetic feature of natural granite. They do not affect durability, value, or lifespan. So if you love a slab that happens to have some pitting, that is simply the character of real stone. Still choosing your countertop?

Frequently Asked Questions
Are pits in granite countertops normal?
Yes. Pits are a natural feature of granite, formed as the stone’s minerals crystallized. They are not a defect and do not affect durability.
Do pits mean my granite is low quality?
No. Pitting is unrelated to quality. Many premium granites show pits simply because of their coarse, crystalline structure.
Can pits in granite be filled?
Yes. If you prefer a smoother look, a fabricator can fill pits with a clear or color-matched resin.
Do all granite countertops have pits?
Not all, but many do — especially coarse, speckled colors. Finer-grained granites tend to show fewer.
Are pits the same as cracks?
No. Pits are normal surface gaps between crystals. Cracks are actual damage. The two are not related.
