onlyfire Fire Glass Diamonds 1 in — 10 lb Reflective Tempered Fire Pit Glass, Pre-washed Sparkle

Onlyfire 10 lbs Fire Glass Diamonds are 1-inch, multi-faceted tempered glass gems designed to replace lava rock and create a sparkling, low-maintenance accent for gas fire pits and decorative projects.

These diamond-cut glass pieces combine jewel-like daytime color with dramatic nighttime sparkle. Manufactured from tempered glass, they tolerate high heat and are pre-washed for immediate use. The smooth, rounded facets catch and reflect flame light differently than round beads, producing a layered, shimmering effect while remaining easy to handle and simple to clean.

How do these glass diamonds perform in a fire pit?

Onlyfire diamonds are tempered to withstand the high temperatures produced by propane and natural gas burners without melting or producing soot. Their flat facets reflect flame and ambient light, creating a multi-dimensional glow that enhances the look of any burner system.

• Tempered to resist heat up to typical gas-fired temperatures
• Pre-washed and ready to pour over burner pans
• Compatible with propane and natural gas setups
• Won’t produce smoke, ash, or odor like wood fuels

Will these glass diamonds be safe and easy to maintain?

The diamonds feature smooth, slightly rounded edges for comfortable handling and are engineered not to shatter into sharp fragments under normal use. Maintenance is straightforward: occasional rinses or a vinegar-and-water soak restore shine without special cleaners.

• Rounded edges reduce the risk of cuts during handling
• Simple cleaning: rinse or vinegar solution for shine
• Durable finish: non-toxic and UV-resistant colors
• Low dust compared with crushed lava rock

How much coverage does a 10 lb bag provide and how do I use it?

A single 10 lb bag is sized for many standard fire pits and small fire tables as a top layer over the burner. For even flame performance, pour glass to manufacturer-recommended depths and keep glass clear of direct burner ports where specified.

• 10 lb bag intended for typical residential fire pits and tables
• Pour evenly across the burner pan to recommended depths
• Pre-washed pieces go straight into the fire feature
• Combine bags or colors to cover larger or deeper installations

How can I use these diamonds beyond fire pits?

Onlyfire glass diamonds serve as decorative accents in multiple settings. Use them in indoor vases, terrariums, water features, or aquarium displays (verify aquarium-safe labeling), and as a colorful top layer in planters and craft projects.

• Decorative filler for vases, bowls, and centerpieces
• Substrate or accent in water features and garden displays
• Colorful top layer for planters and tabletop décor
• UV resistant and color-stable for outdoor use
