GASPRO Fire Glass Diamonds for Gas Fireplace & Fire Pit — Caribbean Blue 1in, 20 lb, Tempered High-Luster

GASPRO Caribbean Blue 1-inch fire glass diamonds are decorative tempered glass pieces that replace lava rock to create brighter, cleaner flames and a jewel-like look in gas fireplaces and fire pits.

These one-inch, high-luster glass diamonds are designed for use with gas fire features to conceal burners and reflect flame light without producing ash or soot. The Caribbean Blue color gives a vivid, gem-like appearance whether the fire is lit or unlit, while tempered construction resists melting and degradation. Delivered in a 20-pound bag, they’re sized for easy placement and redistribution when you’re styling a fire bowl, table, or pit.

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

The Caribbean Blue glass catches and reflects light, making flames appear more colorful and dynamic. When unlit they resemble polished gems; when lit they magnify flame movement for a sparkle effect that’s visible from a distance.

• Vivid gem tone enhances visual contrast with orange flames
• High-luster finish increases light reflection for a brighter fire
• Uniform 1" size creates an even, tiled appearance across the burner

Are these safe and compatible with gas fireplaces and pits?

These pieces are tempered glass made for gas fire applications and do not produce ash, soot, or smoke. They won’t melt under typical gas flame temperatures and effectively hide burner components for a clean installation—confirm your unit supports fire glass before use.

• Tempered to withstand standard gas flame heat
• No ash or smoke keeps the fire feature cleaner
• Cover burner lines and burners for a finished look

How much do I need and how do I maintain them?

A 20-pound bag covers many standard-sized fire pits depending on depth; plan on increasing quantity for deeper bowls. Maintenance is simple: rinse and allow to dry before first use, and occasionally remove and rinse to clear dust or debris.

• 20 lb bag provides practical coverage for most fire tables and medium pits
• Rinse and fully dry before placing over burner
• Periodic rinsing keeps the glass sparkling and free of dust

Will these glass diamonds affect flame performance?

Properly installed, they improve flame presentation without altering burner operation. Keep glass depth appropriate to your burner specifications so airflow and gas flow remain unobstructed for safe, consistent flames.

• Place to manufacturer-recommended depth to avoid smothering flames
• Do not pile high over vents or ports—maintain clearance
• Use on gas-only fire features; not for wood-burning fireplaces

Who is this for: The GASPRO Caribbean Blue fire glass is aimed at homeowners and designers who want a low-maintenance, visually striking upgrade for gas fire pits or tables. It’s ideal for outdoor living spaces, patios, and hospitality settings where a clean, gem-like aesthetic and easy upkeep are priorities. Confirm your fire appliance supports decorative fire glass, rinse and dry the pieces before first use, and enjoy a brighter, cleaner flame presentation.
