The Edelstein Effect, also known as the Edelstein Phenomenon, is a phenomenon in which certain gemstones exhibit a change in color when viewed under different light sources.
The Edelstein Effect is caused by the interaction between the gemstone's crystal structure and the light that passes through it. The crystal structure of the gemstone acts as a filter, allowing only certain wavelengths of light to pass through, resulting in the observed color change.
The Edelstein Effect can be observed in various gemstones such as alexandrite, opal, and labradorite. However, it is most commonly associated with the gemstone phenomenon known as "color-change", where the gemstone appears to change color when viewed under different light sources.
The Edelstein Effect is highly valued in the gemstone industry as it adds a unique and desirable quality to gemstones. Gemstones that exhibit the Edelstein Effect are often more valuable and sought after by collectors and buyers.
While the Edelstein Effect is a natural phenomenon, it can also be artificially created through various treatments and enhancements. However, these artificially created effects are not as highly valued as the natural ones and can often be easily detected by experts.
