Skyflame Black Natural Lava Rock Pebbles
Best for base-layer use and hiding pipes, these lava rocks provide a natural aesthetic with a porous surface. They work well as a fire pit foundation or mixed with glass for texture. Suitable for indoor or outdoor fire features. Caution: avoid over-packing in tight burner zones to prevent airflow obstruction.

Best for modern gas fireplaces and small to medium fire pits, these flat amber beads deliver a high-lustre, jewel-like glow. They are non-toxic and designed for gas use. Choose this if you want a bright daytime sparkle and a warm amber hue at night. Limitation: glass beads can settle and require occasional rearrangement for even flame spread.
Ausluru Flat Glass Marbles (Cobalt)
Best for decorative fire pits and vases, cobalt glass marbles provide a cool-toned contrast that can enhance blue or white flame accents.

Ausluru Flat Glass Marbles (Amber)
Best for adding warmth and a golden glow, amber glass marbles suit both indoor and outdoor settings. They pair well with warm flame colors and lighter fire features. Limitation: lighter colors may show soot with heavy use; regular cleaning helps maintain their reflective quality.

Choose this if you want a dynamic, multicolor display. Caution: color mix may shift visually with different flame colors and lighting conditions.
Buying Guide
What to consider when choosing flat stones or glass for a fireplace or fire pit:
- Purpose: Base layer, decorative topping, or accent lighting. Base layers should be heat-resistant and non-reactive with flame sources.
- Material: Glass beads provide reflective glow and color; lava rock offers a natural, matte backdrop and can conceal pipes.
- Size and shape: Flat or faceted beads distribute heat and flame visually; ensure size is compatible with burner gaps and security guidelines.
- Color and finish: Luster and color affect daytime aesthetics and nighttime glow. Consider how colors interact with flame colors.
- Maintenance: Some beads require periodic repositioning to maintain even flame spread; others are low-maintenance.
Practical considerations and tips
- Always follow manufacturer guidelines for the specific fire feature, including burner type and maximum load.
- Maintain safe clearance around gas lines and ensure proper ventilation for outdoor installations.
- For a cohesive look, pick one color family and a texture that matches your fireplace surround.
