Natural blue diamonds have particularly high asset value among "fancy colored diamonds" and are known as a gemstone sought after by VIPs, whose prices are rising again, and are highly regarded for their particularly beautiful color.
Because of their color vibrancy and clarity, and their rarity compared to colorless diamonds, natural blue diamonds are extremely expensive and highly sought after by collectors and gemstone enthusiasts due to supply and demand.

Natural blue diamonds are formed because of the interaction of boron and nitrogen in their crystal structure, which gives them their blue color.
Blue diamonds are formed in underground environments where specific formation conditions are present.
Boron, nitrogen, etc. are present, and high pressure and high temperature conditions are required.
It is extremely rare for these conditions to be present at the same time, which is why the formation of blue diamonds is so rare.
