About Excelsior Gold Radianz
Excelsior Gold Radianz quartz - what to know
Character
How Excelsior Gold Radianz reads in a kitchen
Excelsior Gold Radianz is a gold-toned quartz that adds warmth and a touch of luxury — pairs especially well with cream or off-white cabinetry and brass or champagne hardware.
South Florida fit
Why quartz works in our climate
Quartz is one of the strongest countertop choices for Palm Beach County kitchens. The surface is non-porous (so it won't absorb spills the way a natural stone can), it's highly heat-resistant up to the typical countertop range, and it shrugs off humidity — no sealing required, ever. Excelsior Gold Radianz ships with the same maintenance profile as every other quartz in this catalog.
Pairings
Cabinetry, hardware, and design context
Excelsior Gold Radianz pairs especially well with brass or champagne-bronze hardware, warm-white or cream cabinets, and rift-cut oak or natural-walnut accents. We always recommend laying the actual slab next to your cabinet sample before final commitment — quartz photographs differently from how it reads in person under your kitchen's actual lighting.

Frequently Asked Questions
Common questions about Excelsior Gold Radianz
Does Excelsior Gold Radianz need to be sealed?
No. Quartz is engineered (roughly 90–93% natural quartz aggregate bound with resin) and is non-porous, so it never needs sealing. Wipe daily with mild soap and water; avoid harsh abrasives and leaving acidic spills (citrus, vinegar) sitting on the surface for extended periods.
Is Excelsior Gold Radianz heat resistant?
Quartz handles brief heat contact well, but the resin binder can discolor under prolonged direct heat. Use a trivet for hot pots and pans straight off the stove. Don't set a heat-treated cast-iron skillet directly on the slab. No quartz is heat-proof in the way a true natural stone or solid-surface stone like soapstone is.
What's the warranty on Excelsior Gold Radianz?
Excelsior Gold Radianz ships with the Radianz manufacturer warranty. We'll confirm the exact current warranty terms with the distributor during your project so you have the current language in writing.
