What comes to your mind when you hear the word ‘diamond’? For many, it’s a sparkling gem that stands out among other gemstones. However, diamonds are far from being as uniform as they might seem. There is a wide variety of diamonds, each distinct in its own way.
These gems come in different colours, clarity, carat weight, and shapes. Their origins, whether from deep within the earth or even from space, add to their unique stories.
Understanding these different types of diamonds is crucial, as it influences the choice of diamonds for rings, earrings, bracelets, or necklaces. There’s a lot to learn about diamonds before embarking on the journey of buying them.
In the next few minutes, you will know more about how many types of diamonds there are. Welcome to the world of diamonds!
Types of Diamonds by Origin
Diamonds don’t always come from a single location, different diamond types come from different geographical locations. Their sources vary, affecting the environment and people’s lives differently.
Mined Diamonds
Mined diamonds, obtained through traditional methods, involve using bulldozers, blasting, hydraulic equipment, and other intense means to extract the stones from the ground. Though costly, this method provides many jobs and boosts local economies, especially in regions where diamond mining is prevalent.
Benefits of Mined Diamonds

Additionally, lab-grown diamonds offer consistency in quality and availability. The ability to produce diamonds on demand ensures a stable supply, avoiding the price fluctuations often seen in the mined diamond market due to geopolitical issues or supply chain disruptions.
Lab-grown diamonds present a compelling alternative to mined diamonds. They offer ethical production, reduced environmental impact, cost-effectiveness, and consistent quality, making them the preferred choice for conscientious consumers looking for sustainable and affordable luxury.
Types of Diamonds by Categories
Many people think that diamonds come from coal, but this is a misconception. In reality, diamonds can contain various chemical elements like boron and nitrogen, which significantly influence their characteristics. Scientists classify diamonds into four main types based on these chemical impurities.
Type Ia Diamonds
Type Ia diamonds, often called "cape" diamonds, comprise about 95% of natural diamonds. They range in color from nearly colorless to light yellow due to the presence of nitrogen atoms that are tightly clustered within their structure. This nitrogen bonding affects the diamond's color and can give it a slightly yellowish tint. These diamonds are the most common and are found in many of the natural diamonds on the market.
Type Ib Diamonds
Type Ib diamonds, also known as "Canary" diamonds, are extremely rare and renowned for their intense yellow color. Unlike Type Ia diamonds, the nitrogen atoms in Type Ib diamonds are dispersed rather than grouped closely together. This spread of nitrogen leads to their distinctive, vivid yellow hue. Most fancy-colored diamonds available for purchase fall into this category, making them highly sought after for their vibrant coloration and rarity.
Type IIa Diamonds
Type IIa diamonds, sometimes referred to as "Golconda" diamonds, are prized for their exceptional purity. These diamonds are typically colorless because they lack both nitrogen and boron impurities. The absence of these elements means Type IIa diamonds are the purest form of diamonds, often displaying extraordinary clarity and brilliance. Their rarity and purity make them highly desirable, and they are frequently featured in high-end jewelry.
Type IIb Diamonds
Type IIb diamonds are known for their striking light blue or gray colors, a result of having high levels of boron. The presence of boron in these diamonds gives them their unique hues, distinguishing them from other types. These diamonds are relatively rare and can exhibit a beautiful range of blue shades, making them a captivating choice for those seeking something unusual and distinctive. Their color and scarcity contribute to their special appeal.
Types of Diamonds by Condition
Another way to classify diamonds is by their natural features and whether any modifications have been made.
Natural Diamonds
Natural diamonds form deep within the Earth under extreme pressure and heat, resulting in their unique and often irregular shapes. Each natural diamond is distinct, with its own set of natural inclusions and imperfections, making every gem one of a kind.
Characteristics
- Unique Formation: Each diamond has distinct natural inclusions and growth patterns.
- Natural Color Variations: Colors can range from clear to shades of yellow, brown, or even rare colors.
- Inclusions and Flaws: Internal flaws, known as inclusions, are natural and contribute to the diamond’s uniqueness.
- Irregular Shapes: Often have unique, irregular shapes due to their natural formation process.
- Authentic Appeal: Retains natural characteristics and authenticity, reflecting its geological history.
Treated Diamonds
Treated diamonds are natural diamonds that have undergone enhancements to improve their appearance. These treatments can include high-temperature, high-pressure processes or laser drilling to remove imperfections and enhance color.
Characteristics
- Enhanced Clarity: Treatments can reduce or eliminate visible inclusions and improve transparency.
- Improved Color: Color can be enhanced to achieve a more uniform or vibrant hue.
- Uniform Appearance: Often have a more consistent appearance compared to natural diamonds.
- Modified Features: Treatments can include laser drilling or high-pressure, high-temperature processes.
- Maintained Fundamentals: Despite enhancements, they retain the fundamental properties of natural diamonds.
