What is fancy color diamond?

Fancy diamonds are a type of diamond. Usually diamonds have a transparent color, but colored diamonds are diamonds other than transparent. Colored diamonds in the world are also called fancy colored diamonds. The main cause is the color produced by the changes in the particles in the colorless diamond. Different changes produce different colors. Therefore, the rarer the color, the higher the value.

The colors of colored diamonds are golden yellow, brown, and green. Others such as pink, red, and blue are rare, and they are often encountered but not available. Like the blue Hope diamond, it is a rare treasure, and it is of course not cheap. High-quality pink diamonds are also regarded as rare and precious, and Australia is the only fixed source of pink diamonds in the world.

The world of diamonds is not only one color, but also colorful. Most people think that the whiter the color of the diamond, the better. In fact, the economic value and collection value of colored diamonds are also very high, because she is rarer and more precious than white, creating her extraordinary charm.

Diamond, also known as "pure carbon", is generally called diamond in chemistry. Diamond is a colorless octahedral crystal, linked by carbon atoms with four valence bonds, and is currently the hardest substance known to exist naturally. Generally speaking, diamonds refer to diamonds that have been polished, and diamonds refer to rough diamonds.

In diamond crystals, carbon atoms are connected to each other in a tetrahedral bond to form an infinite three-dimensional framework, which is a typical atomic crystal. Each carbon atom forms a covalent bond with the other 4 carbon atoms via sp3 hybrid orbital to form a regular tetrahedron. Since the CC bond in diamond is very strong, all valence electrons participate in the formation of covalent bonds, and there are no free electrons, so the hardness of diamond is very large, the melting point is 6900 degrees Fahrenheit, and the ignition point of diamond in pure oxygen is 720 ~ 800 ℃ , It is 850～1000℃ in air, 2000～3000℃ under vacuum, and it is not conductive. In industry, diamonds are mainly used to make probes and grinding tools for drilling, and diamonds with complete shapes are also used to make high-end ornaments such as jewelry, and their prices are very expensive.

Colored diamonds are very rare diamonds in the world. According to statistics from relevant experts, for every 100,000 gem-quality diamonds produced, only one colored diamond is possible, and the probability of being unearthed is only 1 in 100,000. The pink, green, red, and fancy yellow diamonds are more precious and rare with their unique brilliant colors and brilliance. They have deadly magic power and make the world obsessed. So owning a colored diamond is a dream dream of many people, of course, this is not something everyone can achieve! But I don’t think there is any need for you to regret it. In many cases, knowing how to appreciate is a kind of enjoyment.
