The Quantum Pack of these glow stones come in a lovely aqua hue reminiscent of bioluminescent organisms such as fireflies, jellyfish, and some species of fungi. According to Core Glow, after 10-20 minutes of exposure to daylight or lamplight, the CORE Glow products can maintain its afterglow in the dark for about 10-12 hours.

Core Glow Stones are featured at our Giovale Open Deck Observatory. They are imbedded into our concrete walkway and help to provide a lit pathway during the night.
