Quick answer: Yooperlite is a rock containing fluorescent sodalite that glows orange under UV light; opalite is a man-made glass with an opal-like glow; a prophecy stone is a natural iron-manganese nodule from the Egyptian desert. Each is labeled for what it is on our product pages.
Yooperlite
Discovered on Lake Superior beaches in Michigan, yooperlite looks like plain gray rock until you shine a UV flashlight on it — then orange specks light up.
Opalite
Opalite is glass, not a natural opal. It is loved for its soft blue-gold shimmer and we label it clearly.
Prophecy stone
Prophecy stones are natural nodules of iron and manganese oxides found in the Egyptian desert.
Aura quartz
Natural quartz with a thin metallic coating for a rainbow or colored finish — keep it dry.
Frequently asked questions
Do I need a special light to see yooperlite glow?
Yes, a longwave UV (365 nm) flashlight works best.
Is opalite real?
It is real glass, but it is not a natural stone.
Are aura crystals painted?
No — they are coated by bonding a very thin layer of metal to the quartz surface.
