WHY CHOOSE ONYX?
Onyx is a rare, exotic stone. The beauty about onyx is that it is semi-translucent, meaning that light can shine through parts of the stone. Browse some of our most popular onyx colors for countertops and other projects. Remember that as a natural stone, onyx slabs may vary from the images you see online. No two slabs of natural stone are identical. Book an appointment to visit our showroom, conveniently located between Greensboro and Winston-Salem!
How durable is onyx? Onyx is an exotic stone composed mostly of silica and quartz. It is a fragile stone, which makes it useful for high-end, low-traffic uses. Thanks to its translucent qualities, onyx is perfect for back-lit applications, such as bar tops, backsplashes, tables, and desks. Onyx slabs tend to be found in shades of white, cream, pink, and green. Onyx countertop slabs are generally available in a polished finish.

CARE & MAINTENANCE
Cleaning your marble, travertine, or onyx countertops after each use (or at least daily) is recommended. Use warm, soapy water or any ammonia-free and bleach-free cleaning solution to wipe up dirt, spills, or any other residue. Feel free to also use any product specifically marketed as a marble cleaner or marble-safe product. You can also ask us about our 3-in-1 “Cleaner, Protector, Polisher”, available for purchase!
Sealing
In order to help protect your marble, travertine, or onyx, a sealer solution applied (either the standard 1-year or upgraded 15-year option, depending on your selection) at the time of fabrication. The sealer prevents liquid absorption and staining. If you select the standard 1-year sealer, you must remember to re-seal the stone one year after our factory sealer was applied. A properly applied sealer will cause water to bead up on the surface of the stone, rather than penetrate the stone.
Heat
Marble, travertine, and onyx are heat-resistant stones. This gives you the ability to place hot pots directly on the surface. However, it is best practice to use a heat trivet as extra protection. As with any product, marble and travertine are not indestructible.
Scratching
Marble, travertine, and onyx are very prone to scratching. Avoid using sharp knives and other sharp objects directly on your countertops. Also avoid dragging or rubbing coarse/sharp items across your countertop. When cutting/chopping, it is best practice to use a cutting board. Expect that your natural marble or travertine countertops will show signs of wear and tear with time.
Staining & Etching
Marble, travertine, and onyx are very porous stones, thus susceptible to staining and etching. Etching is when a very acidic or basic product erodes the minerals in the stone, thus creating a dull spot. Sealer helps prevent liquid absorption, thus preventing staining; but it does not always prevent etching. Thus, it is best practice to clean up liquid spills immediately, especially spills such as coffee, red wine, vinegar, lemon juice, or strong soaps and detergents. If you begin to notice discoloration or watermarks on your marble, travertine, or onyx surface, please contact us as soon as possible.
Durability
Marble, onyx, and travertine can chip or break if impacted by a heavy object. Do not stand on your countertop or bang items against it. Use care when placing large or heavy objects on your countertops.
