Bright diamonds are rare in nature. Most crystals are almost transparent. A diamond gets its color when a foreign substance gets into its structure during its formation.

The most famous collection of colored diamonds is the Aurora Pyramid of Hope. It is stored in the London Natural History Museum.
⠀
Jewelers use a different cut for such diamonds, since the color is refracted differently in them. Such stones are also called Fancy.
⠀
Paradoxically, only completely transparent diamonds can compete in price with colored diamonds. Many jewelry houses have colored diamonds.
⠀
Many stars consider it a source of pride to have jewelry with colored diamonds in their wardrobe. Among such owners are Jennifer Lopez with a Harry Winston ring and Blake Lively with a Lorraine Schwartz ring.

Interestingly, the prototype of the famous jewelry from the movie "Titanic" became a real decoration - a large blue Hope diamond, which was long owned by Cartier and is now in the Smithsonian University.
