Understanding whether lab-grown diamonds are 'real' revolves around defining what 'real' means when it comes to diamonds. By gemological standards, lab-grown diamonds are indeed real diamonds, with the same optical, chemical, and physical properties as their natural counterparts. They are not imitation diamonds, like cubic zirconia or moissanite, which are materials that look similar to diamonds but have different properties.
We recognize that the appeal of lab-grown diamonds extends beyond their authenticity. They provide an alternative choice for consumers who prioritize ethical considerations and sustainability, as they do not require mining. Moreover, they can often be more affordable than natural diamonds while maintaining the desired quality and aesthetics, allowing people to purchase larger or higher-quality diamonds than they might otherwise be able to afford.
What Are Lab-Grown Diamonds?
In our exploration of diamonds, we must clarify that lab-grown diamonds share identical properties with those mined from the earth. Let's examine their nature and the innovative methods behind their creation.
Definition and Core Concepts
Lab-grown diamonds, also referred to as synthetic diamonds, created diamonds, or laboratory-grown diamonds, are true diamonds produced through technological processes rather than mining. We recognize these gems for having the same chemical composition, crystal structure, optical properties, and physical characteristics as natural diamonds, to the extent that they are graded on the same criteria: cut, color, clarity, and carat weight.
- Chemical Composition: Pure carbon, crystallized in an isotropic 3D form
- Hardness: These stones are also rated a 10 on the Mohs hardness scale, the highest level of scratch resistance a material can achieve.
Creation Processes
Our understanding of modern technology has allowed us to develop two primary methods for creating lab-grown diamonds: High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD).
- HPHT Method
- High Temperature: Mimics the natural formation conditions of diamonds by subjecting carbon material to temperatures above 1,400°C.
- High Pressure: Simultaneously applies pressures of approximately 5 GPa (gigapascals).
- CVD Method
- Starts with a thin slice of diamond seed.
- Involves breaking down gases within a vacuum at low pressures and high temperatures, causing carbon atoms to accumulate on the diamond seed, layer by layer.
Both methods create diamonds that can serve various purposes, from industrial applications to gem-quality stones for jewelry.
Comparing Lab-Grown and Natural Diamonds
In our examination of lab-grown and natural diamonds, we focus on their properties, differences in appearance, and how they are valued in the market. Both share the same base element, carbon, but their journey to becoming a diamond diverges significantly.
Physical and Chemical Properties
Lab-grown and natural diamonds are identical in terms of their chemical composition; both are pure carbon. Geologically sourced natural diamonds form over billions of years under high-pressure and high-temperature conditions deep within the Earth. Lab-grown diamonds, also known as synthetic diamonds, replicate this process in a controlled setting, resulting in the same crystal structure as their natural counterparts. When it comes to the classic 4Cs (cut, clarity, color, and carat), lab-grown diamonds can be engineered to meet specific standards, much like natural diamonds that are cut from rough stones.
Optical and Structural Differences
Optically, lab-grown and natural diamonds can be indistinguishable to the naked eye. However, under magnification or using specialized equipment, there can be subtle differences in crystal growth patterns and inclusions. Manufacturers can often control the environment when creating lab-grown diamonds, which may lead to fewer inclusions and a wide range of available colors, including some that are rare in nature.
Market Perception and Value
Our industry's perception of lab-grown versus natural diamonds has evolved over time. Both are considered "real" diamonds by the Federal Trade Commission, but natural diamonds are traditionally viewed as more valuable due to their rarity and the ancient processes that create them. Lab-grown diamonds tend to have a lower resale value, influenced by their abundance and the capability to produce more on demand. The diamond industry has seen lab-grown diamonds decrease in value over recent years while natural diamonds have maintained more stable pricing.
Quality Assessment of Lab-Grown Diamonds
When we assess lab-grown diamonds, we focus on key attributes such as clarity, cut, carat, and color, which determine their quality. These diamonds undergo rigorous certification and grading processes, comparable to natural diamonds, ensuring that their valuation is based on universally recognized standards.
Certification and Grading
Lab-grown diamonds are subjected to the same grading and certification protocols as mined diamonds. This practice involves a detailed analysis of a diamond's four Cs: clarity, cut, carat weight, and color. Reputable gemological laboratories issue certification documents that attest to each stone's attributes, providing assurance to both buyers and sellers. These certificates serve as validation of a diamond's quality and characteristics.
The Role of GIA
The Gemological Institute of America (GIA) is a key authority in the diamond grading field, including for lab-grown diamonds. We recognize the GIA's efforts to differentiate their reporting for lab-grown and mined diamonds, thereby maintaining transparency in the market. The GIA Laboratory-Grown Diamond Report we discuss focuses on the same four quality parameters as for natural stones. Notably, the GIA report indicates the lab-grown origin of the stone to avoid any confusion, providing clear, unbiased information about the diamond's characteristics.
By acknowledging these aspects, we can appreciate the sophistication of lab-grown diamonds and the scrupulous assessment they undergo through institutions like the GIA.

Technical Insights
In this section, we'll elucidate the technicalities involved in creating lab-grown diamonds (LGDs), from the intricate growth process to the advanced equipment and technology required to mimic the conditions under which natural diamonds form.
Understanding the Growth Process
LGDs are created using one of two main methods: High Pressure, High Temperature (HPHT) or Chemical Vapor Deposition (CVD). Both methods simulate the environment necessary to grow a diamond.
- HPHT Process: Here, we place a small diamond seed in carbon-rich material. Subjecting this setup to high temperature—around 1400-1600°C—and high pressure—approximately 5-6 GPa—facilitates the transformation of carbon into a diamond around the seed.
- CVD Process: This technique involves heating a mixture of hydrocarbon gas—usually methane—under a vacuum to extremely high temperatures, causing carbon atoms to accumulate on a diamond seed, layer by layer, growing the diamond up to several carats over time.
Equipment and Technology
To replicate such conditions, precise and sophisticated equipment is essential.
- HPHT Equipment: We use belt presses, cubic presses, and split-sphere (BARS) presses. The choice is guided by the required pressure and temperature range and the desired size and type of diamond to be cultivated.
- CVD Technology: We rely on a vacuum chamber and gas activation technology. Gases are introduced into the chamber, and a microwave power supply ignites a plasma, disassociating the molecules and initiating the growth on the diamond seed.
Throughout both processes, careful monitoring by research scientists ensures the quality and consistency of the LGDs produced. Our understanding and utilization of these technologies have paved the way for the reliable production of LGDs with characteristics comparable to those of mined diamonds.
