Kryptonite (Glow Stone)
This man made glow stone also called kryptonite is in raw form and perfect for fairy gardens, indoor decor, crafts, and lots more. Absolutely amazing. Shine some light on it for a few minutes or leave it to 'charge' in the sun, and then watch it glow when placed in the dark. Glows longer when placed in direct light for long periods of time. These all vary in size and style.
