What Is Strong Blue in Diamonds?
Are you wondering what strong blue in diamonds is? Does this factor affect the value of a diamond? If you are researching diamonds and gemstones, you definitely need to read this entire article.
What is strong blue in diamonds?
Strong blue is also called Fluorescence or diamond fluorescence. This is the light we can see when a diamond is exposed to ultraviolet rays. It is known as a distinctive characteristic of some natural diamonds.
According to research, more than 30% of natural diamonds fluoresce blue at different intensities. Diamonds in the D to H color grades with high fluorescence will turn milky when exposed to ultraviolet light. At this point, the diamond becomes less brilliant, and its value also decreases by 5 to 15%.
Diamonds in the I to J color grades are usually white or off-white. When they interact with ultraviolet rays, they gain superior brightness. Along with that, the value of these diamonds also increases by more than 5% and can reach up to 15% compared to the original value.
In diamond certificates, strong blue is noted in the color section. The fluorescence levels increase gradually as Inert, Faint, Slight, Medium, and Strong blue.

Which diamond is the most expensive?
After learning what strong blue in diamonds is, you surely have one more criterion for choosing a diamond. The value of a diamond lies not only in its appearance but also in the mysteries inside. Over time, professional organizations have established many criteria to evaluate diamonds.
Criteria for evaluating natural diamonds
Currently, diamond enthusiasts use the 4C criteria to measure and determine the most accurate price. The 4C criteria correspond respectively to color, Clarity, Cut, and Carat Weight.
Each criterion has gone through extensive testing to ensure the highest quality.
- Color: diamond color is divided into grades from D to Z. The color here actually refers to the transparency of the diamond. The highest color grade is D, characterized by being colorless, extremely rare, and highly valuable. Meanwhile, Z is the least valuable diamond color grade.
- Clarity: this is the measure of the cleanliness of each diamond. Small imperfections such as inclusions, air bubbles, stains, etc. are divided into many different grades. They can only be fully seen under a microscope.
- Cut is the soul of each diamond. A beautiful, high-quality cut helps the diamond sparkle under light. Diamond cut quality has 5 grades: Excellent, Very good, Good, Fair, and Poor. This criterion is very important because it affects the brilliance and fire of the diamond.
- The larger the diamond, the higher the value. Large and rare diamonds carry very great value.
The value of a 3-carat diamond cannot simply be three times that of a 1-carat diamond. This is because it also depends on other factors. A 1-carat diamond can be more valuable if it has an exquisite cut, D color grade, and IF clarity.
