Other Highlights of Understanding Diamonds - Fluorescence
Diamond fluorescence is a light with a different color when exposed to UV (ultraviolet light).
Diamond fluorescence is a phenomenon that occurs when a diamond is exposed to ultraviolet light and emits visible light. Most diamonds emit blue light when exposed to ultraviolet light, but some diamonds also emit yellow, green, orange, red and other colors of fluorescence.
The fluorescence of diamonds is caused by the presence of impurities in them. These impurities absorb ultraviolet rays and re-emit visible light after absorbing energy. Fluorescence has an effect on the value and quality of a diamond because it may change the appearance and color of the diamond. Some people like the fluorescence of a diamond because it adds to the mystery and glamour of the diamond, while others dislike fluorescence because they think it makes the diamond look unnatural.
About 50% of all diamonds on earth have fluorescence. Diamonds have a variety of colors, but most of them are basket-colored and have different strengths and weaknesses, and are classified by the GIA into five grades.[ No fluorescence, weak, medium, strong and very strong ]In the market, the stronger the fluorescence, the lower the value. In the market, usually the stronger the fluorescence, the lower the value.
