fluorescent gemstones

There are some gemstones that emit a neon color when exposed to ultraviolet light. It is thought that the fluorescent substances contained in these materials emit light in response to ultraviolet light. When illuminated with black lights in a darkened room, the neon glow is truly a mystical world. There are many fluorescent gemstones, and they come in a variety of colors. From famous stones that everyone knows to rare rare stones. I think it's fun to collect various things and compare them.
