The blue flame of psychic jewelry is a patented diamond of psychic jewelry. The patent lies in its cutting shape. He cut off all eight sides of the circle 8, and we can also describe it as an octagon.

Since it is called blue flame, his original intention was to choose fluorescent diamonds as the cutting object, but later it was found that it was not easy to find fluorescent diamond blanks, because from the proportion of diamond production, fluorescent diamonds only accounted for a small part of the total output.

Today's blue flame diamonds are both fluorescent and non-fluorescent. If this girl doesn't like fluorescent diamonds, she can tell the clerk when she buys them and ask them to choose a non-fluorescent diamond for you, which will not only satisfy you, but also avoid unnecessary trouble.

I hope it helps you.
