Fluorescence

Fluorescence

The fluorescence effect of a diamond is very important because it affects the color of the diamond. The fluorescence of diamonds is mostly blue, and 90% of diamonds have a slight yellowish tint. Under the influence of ultraviolet rays from sunlight, the combination of blue fluorescence and light yellow will make the diamond appear milky white.

How to Take Care of Your Diamonds

When the diamond ring jewelry is not worn for a long time, it must be cleaned in time before storage. Because of the strong lipophilicity of diamonds, it is easy to be stained with oil stains and become dull, so dust and oil stains accumulate in every corner of the diamond jewelry, seriously affecting its brilliance.

How to clean a diamond ring yourself? Normaltan Jewelry propose to take a bowl of warm water, add a few drops of neutral detergent to it, then use cotton (or a small brush, etc.) dipped in water to gently wipe the diamond jewelry. After the dirt is washed off, rinse it in another bowl of clean water, and then put it in a ventilated place to dry, and the diamond ring can restore its bright original appearance.
