Diamonds are truly precious because only about 20% of mining output meets the standards for jewelry making, while the rest is used in industry. The value of diamonds lies not only in their eternal beauty but also in the harsh formation conditions that have lasted for billions of years underground.

The article below will have Jemmia analyze in detail the quantity, formation process, and special values that diamonds bring to their owners.

Are diamonds really precious?

The rarity of diamonds is not in the total mining output but in the extremely low percentage of diamonds that meet jewelry quality standards. According to gemstone industry reports, although millions of carats are mined each year, in reality, up to 80% of the output only meets industrial standards due to dull color or containing too many impurities.

Only about the remaining 20% possess the purity and color that qualify for high-end jewelry making. Among these, diamonds with D color grade (colorless) or FL/IF clarity (flawless) are even rarer, creating unique and expensive value for this stone in the global market.

Why is the price of diamonds so different from other gemstones?

The value of a diamond is determined by the infinite variation of factors in the 4Cs standard, making no two diamonds exactly alike. The price difference comes from the combination of weight (Carat), color (Color), clarity (Clarity), and most importantly, the cut (Cut).

A diamond only needs a slight improvement in clarity from SI1 to VVS1 or to have an Excellent cut instead of Good to increase its value by tens, even hundreds of millions of VND. In addition, diamonds with certificates from reputable gemological institutes such as GIA (Gemological Institute of America) often have higher liquidity and listed prices than stones of unknown origin.

How harsh are the conditions for diamond formation in nature?

Diamonds are the result of a harsh geological transformation process that has lasted from 1 to 3.5 billion years deep within the Earth. They are formed from the element Carbon under pressure up to 5 gigapascals and temperatures exceeding 1,300°C at depths of about 140km to 190km.

To bring these "essences of heaven and earth" to the surface, ancient volcanic eruptions acted as elevators, transporting diamonds through Kimberlite pipes. Due to the formation process spanning billions of years and the complex, costly, and technical extraction required, diamonds have always maintained their position as the rarest and most sustainably valuable gemstone on the planet.
