The material
One of a kind, every slab.
Quartzite, granite and marble are cut from the earth, not made in a factory. No two slabs repeat, the colour runs through the full thickness, and a polished surface can be refinished decades later. Each stone behaves a little differently, so we tell you what to expect before you choose.
- Best for
- Kitchen islands and counters, fireplace surrounds, bathroom vanities and full-height feature walls. Quartzite and granite for hard-working kitchens; marble where the look matters more than a knife-proof surface.
- Durability
- Granite and quartzite are among the hardest materials you can put in a home. They resist scratches and hold a crisp edge for decades. Marble is softer and develops a patina with use.
- Heat & stains
- Quartzite and granite offer excellent durability and heat resistance, though trivets are recommended for hot cookware.
- Maintenance
- Warm water and a pH-neutral cleaner. A penetrating sealer every 12 months; we apply the first coat at installation. Keep vinegar, lemon and bleach away from marble.
- Look
- Movement, veining and depth that engineered products imitate but do not match. Honed, leathered or polished finishes change how the same stone reads. Book-matched pairs turn two slabs into one dramatic piece.

Natural stone by type
Quartzite, marble and granite
Quartzite
Quartzite is natural stone, quarried and cut into one-of-a-kind slabs. It is very hard, takes heat straight from the pan and resists the etching that marks marble, which makes it a favourite for hard-working kitchens across Northern Virginia. Like all natural stone it is porous, so we seal it at installation and re-seal once a year. If you are choosing between it and engineered quartz, read quartzite vs. quartz: how to choose.
Marble
Marble is prized for its soft veining and the patina it earns over time. It is softer than granite or quartzite, so it scratches more easily, and acids such as lemon, wine and vinegar can etch the polish. Many clients love how it ages; others prefer a marble-look quartz or quartzite for the same veining with less upkeep. For a kitchen specifically, see whether marble is a good idea.
Granite
Granite remains one of the most durable countertop materials. It handles heat, holds a crisp edge for decades and is one of the few surfaces we also install outdoors, around Sterling and across the DMV. Every natural stone slab is scanned at 12K the day it arrives, so you approve the exact layout before we cut.
Good to know
Natural stone, in detail
For most busy kitchens, quartzite. True quartzite is much harder than marble, takes heat well and resists the acid etching that lemon, wine and vinegar leave on marble. Marble is softer and develops a patina over time, which some people love and others do not. Both are natural stone and are sealed at installation. Some stones are sold under trade names that blur the line between the two, so ask us about the specific slab you are considering before you commit. More on marble in a kitchen
Quartzite is far less absorbent than many natural stones, but it is still natural stone, and porosity varies from slab to slab. We seal every natural quartzite countertop with a penetrating sealer at installation and recommend re-sealing once a year, which takes a few minutes with an over-the-counter product. Wiping up oil, wine and coffee promptly keeps it looking new. The once-a-year sealing routine
Taj Mahal is a natural quartzite, quarried as stone and cut into slabs, so every slab is different. Some engineered quartz products use similar names to describe a look-alike pattern. If a sample is labelled Taj Mahal, check whether it is natural quartzite or engineered quartz. The two differ in heat resistance, sealing and price. Quartzite vs. quartz: how to choose
Yes. Granite remains one of the most durable countertop materials. It handles heat, holds an edge for decades and is one of the materials we install outdoors. Today's range runs from quiet, uniform stones to dramatic exotic slabs, and like all natural stone it is scanned at 12K so you can approve the exact layout before we cut. How layout approval works
