4" GRAYSTONE VF SPHERES

Who says a fireplace has to follow the rules? The Real Fyre 4" Graystone Vent-Free Fyre Spheres (Set of 24) trade traditional logs for a striking, contemporary aesthetic — 24 refractory ceramic spheres in a refined Graystone finish that look like they belong in an art gallery as much as a firebox.

But these spheres aren't just a pretty face. Engineered for performance, this set is capable of delivering up to 37,000 BTU/hr of radiant heat output — plenty of warmth to take the edge off even the most stubborn winter evening. Whether your home runs on Natural Gas or Propane, these spheres are ready to work with your existing fuel supply.

Crafted from refractory ceramic, each sphere is built to withstand the rigors of repeated heating and cooling cycles without sacrificing its clean, geometric form. The Graystone colorway is a versatile, premium neutral — sophisticated enough to complement modern interiors, yet grounded enough to feel at home in transitional or even rustic-contemporary spaces.

Installation is straightforward when paired with the correct burner system. These spheres are designed specifically for use with the Real Fyre G23 Vent-Free Burner system (available in 18" and 24" sizes) and are also compatible with the Real Fyre P45 Vented Burner system. Please note: these spheres are intended exclusively for use with Real Fyre Vent-Free Fyre Sphere-compatible systems — not a universal fit for every burner on the market.

Planning to use the 24" G23 system? Make sure your fireplace meets the minimum opening requirements: 30" wide (front), 22" wide (rear), 16" depth, and 17" height. A little measuring now saves a lot of headaches later.

Whether you're refreshing an existing fireplace setup or building out a new one from scratch, the Real Fyre Graystone Fyre Spheres are the kind of finishing touch that guests will notice — and ask about. Refinement, warmth, and a quietly confident design statement, all in one package.
