Diamonds have always attracted attention with their sparkling beauty and luxury, but not every diamond is the same. Each type of diamond has its own distinct characteristics and can be crafted into many styles of beautiful diamond jewelry, unique pieces that highlight the owner's style. Diamonds with large sizes and perfect shapes are always sought after by the elite at sky-high prices. Let Jemmia help you learn more about the common types of diamonds on the market today.
How many types of diamonds are currently on the market?
There are currently two main types of diamonds on the market: natural diamonds and artificial diamonds. Among them, natural diamonds are considered the rarest type, standing out with magnificent beauty and high durability, making them a top choice among gemstones.
Natural diamonds
These are diamonds formed naturally over millions to billions of years under conditions of extremely high temperature and pressure deep within the Earth. This process occurs naturally without human intervention.
After being formed, diamonds are mined from diamond mines around the world. Each natural diamond is unique, highly valuable, and evaluated based on factors such as weight (carat), color, clarity, and cut (cut).
Compared to artificial diamonds that can be mass-produced, natural diamond prices are many times higher thanks to their rarity and the billions of years required for formation deep underground. This is not only luxury jewelry but also a "hard currency" with extremely high liquidity.
Natural diamonds are extremely rare
Artificial diamonds
Artificial diamonds, also called synthetic diamonds, are created in laboratories by recreating temperature and pressure conditions similar to the natural diamond formation process. This production process may take a few weeks instead of millions of years.

Chemically and physically, artificial diamonds have the exact same structure and composition as natural diamonds, but because they are man-made, they are usually more affordable. Although they have a similar appearance and properties, artificial diamonds are often more accessible thanks to their faster creation process and better quality control.

How many types of diamonds are there according to GIA experts?
According to GIA, diamonds are classified based on color and physical composition, helping distinguish between natural diamonds, treated diamonds, and artificial diamonds. Based on chemical composition and structure, diamonds are divided into two main types, I and II, with smaller subgroups such as Ia, Ib, IIa, and IIb.
Type Ia diamonds
Type Ia diamonds are the most common, with about 95% of natural diamonds belonging to this group. This type contains clusters of nitrogen atoms, which affect the diamond's color. Most Type Ia diamonds range from colorless to light yellow. These diamonds are often called “Cape Diamonds” because many are found in the Cape region of South Africa. The presence of nitrogen reduces clarity but still maintains the characteristic beauty of natural diamonds.

Type Ib diamonds
Type Ib diamonds are much rarer than Type Ia, accounting for less than 1% of all natural diamonds. This type contains isolated nitrogen atoms, creating a striking vivid yellow color. Type Ib diamonds are often called “Canary Diamonds” because of their characteristic intense yellow hue. The vivid color and rarity of this type make them a favorite choice for those seeking diamonds with unique colors.
Type IIa diamonds
Type IIa diamonds contain no measurable nitrogen or boron impurities, making them one of the purest types of diamonds chemically. These diamonds may be colorless or have shades of gray, light yellow, light brown, or pale pink. Thanks to their high purity and few impurities, Type IIa diamonds have superior transparency and are considered the most valuable among diamond types.
Type IIb diamonds
Type IIb diamonds are very rare and contain the element boron, which gives them electrical conductivity. Boron is also the factor that creates the characteristic blue or grayish-blue color of this diamond type. Blue diamonds, such as the famous blue “Hope Diamond,” belong to the IIb group and often have high value thanks to their rarity and distinctive beauty.
According to GIA, diamonds are classified based on color and physical composition, helping distinguish between natural diamonds, treated diamonds, and artificial diamonds.
