In Detail: Lab Grown Diamonds vs Natural Diamonds: Which to Buy?
Their identical crystal structure, comparable hardness, and captivating sparkle make them indistinguishable from earth-mined diamonds upon visual inspection. This makes them a sustainable, ethical alternative to mined diamonds.
Compared to natural diamonds, lab-grown varieties are not extracted from the earth, ensuring no impact on native communities or ecosystems. Environmentally conscious consumers find these attributes particularly compelling.
Consumers use the same 4Cs—color, clarity, cut, and carat—to assess the quality and authenticity of lab-grown diamonds, just as they do with natural diamonds.
In fact, when it comes to evaluating lab-grown diamonds, the same criteria apply as with natural diamonds, ensuring you get the same level of quality and authenticity. Let’s explore the different types of lab-grown diamonds and what sets them apart.
Types of Lab Grown Diamonds
When exploring the world of lab-grown diamonds, it's important to distinguish between simulant and cultured diamonds, as they are fundamentally different in composition and value.
- Simulant Diamonds
Simulant diamonds, often called imitation diamonds, do not consist of pure carbon and lack the chemical, physical, and optical characteristics of natural diamonds. These alternatives are generally less durable and hold a lower market value.
Common examples include cubic zirconia, which is made from zirconium dioxide, offering the lowest durability and cost, making it popular in costume jewelry. Another simulant, Diamond Nexus, combines carbon with other elements for improved durability compared to cubic zirconia.
Meanwhile, Moissanite, created from silicon carbide, presents a visually striking yet distinct option that is not considered a true diamond.
- Cultured Diamonds
Cultured diamonds are pure carbon, nearly identical to natural diamonds in chemistry and optics.
Cultured diamonds form in a lab under controlled conditions that replicate the natural diamond-creating process, resulting in stones indistinguishable from their mined counterparts to the untrained eye.
The defining distinction is that cultured diamonds possess the same intrinsic qualities and brilliance as those formed in Earth's mantle but with the added benefits of sustainability and traceability, often appealing to environmentally and ethically conscious consumers.

Now, let’s take a closer look at how lab-grown diamonds are made and the fascinating process behind their creation.
How Lab Grown Diamonds Are Made
Lab grown diamonds are created using two primary methods: the High-Pressure High-Temperature (HPHT) and the Chemical Vapor Deposition (CVD) processes. These methods mimic the natural conditions under which diamonds are formed, allowing us to produce diamonds in a more controlled environment.
- High-Pressure High-Temperature (HPHT) Diamonds
The HPHT method seeks to replicate how diamonds naturally form deep beneath the Earth's surface.
It involves placing a diamond seed inside a chamber with carbon and then subjecting it to extremely high pressure and temperature.
The carbon atoms begin to crystallize around the seed, eventually forming a diamond. One of the benefits of HPHT is the ability to modify the diamond's color by introducing different elements during the process, such as nitrogen for yellow diamonds or boron for blue ones.
There are various press types used in this method, like the cubic or belt press, each contributing to the diamond's quality in unique ways.
- Chemical Vapor Deposition (CVD) Diamonds
In the CVD process, a diamond seed is placed in a controlled vacuum chamber filled with carbon-based gasses. The process breaks down these gasses into plasma, causing carbon atoms to accumulate layer by layer onto the diamond seed.
This method is typically favored for producing larger and more uniform diamonds, which are particularly useful for industrial purposes. Treatments like annealing can refine the diamonds further, altering their colors through processes like irradiation.
While HPHT diamonds might contain metallic inclusions and CVD diamonds may have black graphite spots, these can be identified under magnification. These traits differentiate lab-grown diamonds from each other and from natural diamonds.
Their hardness and thermal properties make them valuable in technology, exemplifying the blend of science and beauty.
Deep Dive: Differences and Comparison: CVD vs. HPHT Lab-Grown Diamonds
Equally captivating is the wide array of hues they come in, showcasing the diverse colors of lab-grown diamonds that cater to different preferences and styles.
Colors of Lab Grown Diamonds
Lab-grown diamonds offer a spectrum of colors, presenting an appealing alternative. The variety results from the different types of trace elements present during diamond formation, and this section explores the prevalence and characteristics of some common types like IIa, IIb, and Ib.
- Prevalence and Characteristics of Types IIa, IIb, and Ib
Among lab-grown diamonds, Type IIa is known for its exceptional clarity and brilliance due to an absence of nitrogen and other impurities.
These diamonds usually appear colorless or near-colorless, but sometimes exhibit light shades like yellow or pink because of structural anomalies.
Type IIb diamonds, on the other hand, boast a rare and beautiful light blue hue, credited to the presence of boron impurities.
In contrast, Type Ib diamonds are characterized by their vibrant and diverse color palette, notably yellow. This variety arises from single nitrogen atoms embedded in their structure.
From rings to earrings, explore Everyday’s vibrant, and customizable collection of Type II lab-grown diamond jewelry.
- Color Varieties Such as Yellow, Green, Pink, Blue, and Colorless
Colored lab-grown diamonds reflect the marvel of modern science. Yellow diamonds are primarily Type Ib, due to nitrogen atoms that impart their vibrant hue. Green and brown shades can sometimes occur, adding to the array of available choices.
Pink lab-grown diamonds, a rarity in nature, are cultivated using nitrogen vacancy (NV) centers formed through irradiation and annealing processes.
The appeal of colored lab-grown diamonds doesn't just lie in their beauty; they are often more affordable than their natural counterparts.
Their production also tends to be more ethical, aligning with current shifts in consumer sentiment and increasing demand.

Several key aspects contribute to these stunning hues, which brings us to the factors influencing diamond colors and how they come to be.
Factors Influencing Diamond Colors
The colors of lab-grown diamonds are influenced by the presence of impurities and the technology used in their creation. This section explores these factors and how they compare with natural diamonds.
- Role of Impurities in Diamond Color
The color of a diamond is determined by its elemental impurities. For lab-grown diamonds, the most impactful impurities are nitrogen and boron.
Nitrogen impurities give diamonds a yellow shade by absorbing blue light, while boron results in a blue color by absorbing the red, yellow, and green parts of the spectrum. Producers can manipulate these impurities to create diamonds with specific hues.
- Difference Between Natural and Lab-Grown Diamond Colors
Natural diamonds can have varied colors due to the unpredictable nature of their formation. In contrast, lab-grown diamonds offer more consistency in their color. This reliability is appealing to consumers who desire a specific hue.
- Technologies Impacting Colors: HPHT and CVD
Lab-grown diamonds are primarily produced using two methods: High-Pressure High-Temperature (HPHT) and Chemical Vapor Deposition (CVD). The HPHT method is excellent for producing colored diamonds.
It provides controlled conditions where impurities such as nitrogen and boron can be deliberately introduced to achieve the desired color. On the other hand, CVD excels in creating colorless diamonds because it results in exceptionally pure crystals.
However, it can also produce colored diamonds by carefully controlling the introduction of impurities.
Both HPHT and CVD offer significant control over the final color of the diamond, allowing manufacturers to meet specific consumer preferences.
Beyond just aesthetics, these advancements also bring important market and ethical considerations to the forefront, reflecting the growing awareness among buyers.
