Glow in the Dark Gemstones: Luminescent Wonders of the Earth

Introduction
The world of gemstones is filled with dazzling hues and captivating brilliance. Among these treasures, glow-in-the-dark gemstones stand out as enigmatic wonders that captivate and enchant. These gems possess the extraordinary ability to absorb light and emit it as a soft, ethereal glow in the darkness, creating a mesmerizing spectacle.

Science of Luminescence
The luminescent property of glow-in-the-dark gemstones is attributed to the presence of trace elements within their crystal structure. These elements, such as manganese, chromium, or zinc, act as activators that absorb energy from various light sources, including sunlight, UV rays, and even artificial light. Once excited, these elements release the absorbed energy as a delayed emission of light, resulting in the characteristic glow.
