onlyfire Fire Glass Diamonds for Fire Pits, 10 lb 1 inch Diamond-Cut — Tempered Reflective Sparkle

Onlyfire 10 lbs Fire Glass Diamonds are tempered, one-inch faceted glass pieces designed to replace lava rock for gas fire pits and decorative displays, offering high-heat durability and jewel-like sparkle.

This 10-pound bag contains uniform, one-inch diamond-cut fire glass engineered for propane and natural gas burners. The faceted shape multiplies reflections so the glass looks bright and gem-like in daylight and transforms into warm, dancing points of light when the flame is on. Each piece is tempered to resist extreme temperatures and arrives pre-washed with rounded edges for safer handling and lower maintenance than raw crushed glass or lava rock.

How will these glass diamonds change the look of my fire pit?

The multi-faceted cuts reflect light from many angles, producing a layered, sparkling appearance both with and without flame. Color options let you coordinate the glass with your outdoor design scheme.

• Faceted surfaces increase sparkle compared to smooth glass beads.
• Vibrant color during the day, warm ember-like glow at night.
• Available in single colors and designer blends to match décor.

Are these safe for use with propane or natural gas?

Yes — these diamonds are industrially tempered to tolerate high heat without cracking, melting, or producing soot or odors. They are specifically made for gas-fired applications, offering a cleaner, longer-lasting alternative to wood or lava rock.

• Tempered to withstand temperatures up to approximately 1300°F.
• No smoke, soot, or toxic fumes when used correctly with gas burners.
• Compatible with both propane and natural gas fire pits and tables.

How much glass do I need and how easy is installation?

Each twenty-pound equivalent in coverage depends on the fire pit size and burner depth; this 10 lb bag is portioned for many standard fire pits and fire tables. The product ships pre-washed so you can pour and arrange immediately.

• 10 lb bag is suitable for many small to medium fire pits or as a top layer over an existing bed.
• Pre-washed and ready to pour—no initial cleaning required.
• Rounded edges make handling safer and placement simpler.

How do I clean and maintain the fire glass so it keeps its shine?

Maintenance is low: routine rinsing restores sparkle and removes dust or residue. For fuller cleaning, a gentle vinegar-and-water soak removes buildup without dulling the glass.

• Quick rinse with hose or bucket for light dust and soot removal.
• Vinegar and water soak restores factory shine when needed.
• Non-fading and UV-resistant for long-lasting outdoor color.

Who this product suits: homeowners or renters with gas fire pits, outdoor living enthusiasts, landscape designers, and creatives seeking a low-maintenance decorative element. If you want a safer, cleaner, and more visually striking alternative to lava rock or plain glass beads—whether for a backyard fire table, a patio centerpiece, aquarium substrate, or vase filler—Onlyfire 1" Diamond Fire Glass provides durable tempered performance and eye-catching color that elevates both daytime décor and nighttime ambiance.
