Is your outdoor fire pit looking stale? Instead of buying a new one, get your DIY on the easy way with Celestial Tempered Fire Glass in Diamond Starlight. This clear glass emulates crushed diamonds — you'll love the way it catches the light when your fire is ablaze!

Celestial Tempered Fire Glass was developed specifically for fire pits and their extreme heat. It's rigorously quality tested to provide season after season of elegant beauty. Why choose plain, dull lava rocks when you can bring your fireplace to shimmering, sparkling life? Watch it instantly turn into the showpiece of your patio or deck.

The Celestial difference:

  • More luminous than other brands. Since our crushed fire glass is not tumbled, its smooth, flawless surface reflects more light.
  • Won't melt or discolor. Your Celestial fireplace glass is designed to withstand extreme heat. It won't fade or melt and retains its brilliant shade over time.
  • Non-polluting. This heat-resistant glass is safe to use outdoors — no need to worry about toxic, smelly fumes being released into the air.
  • Doubles as a decorative accent. Have the do-it-yourself bug? Add a few handfuls of our fire pit glass to water features, clear vases, and decorative bowls to lend style and visual pizzazz to your surroundings.
  • No-mess container. Celestial fire glass is packaged in a reusable plastic jar with a convenient carry handle to make your life easier.
