Lab-grown diamonds, also known as lab-created or man-made diamonds, have gained significant popularity in recent years. These diamonds, created through advanced technological processes, offer an ethical and sustainable alternative to mined natural diamonds while delivering the same sparkle and beauty. In this blog, we’ll explore everything you need to know about lab-grown diamonds, including where to buy them.
Shopping for Lab-Grown Diamonds? Some of our vetted vendors offer premium lab-grown diamonds, both loose or set-in finished jewelry. Check out Whiteflash and their precision cut lab-grown diamonds, James Allen, and Blue Nile extensive online collections.
Understanding Lab-Grown Diamonds?
Lab-grown or lab-created diamonds are diamonds that are created in controlled laboratory environments rather than being mined from the earth. They share the same chemical composition as natural diamonds, which is pure carbon arranged in a crystal lattice structure. The key difference is their origin and the way they are formed.
How Are Lab-Grown Diamonds Made?

Lab-grown diamonds have surged in popularity, offering an ethical and cost-effective alternative to mined counterparts. Here, we explore the two distinctive methods of how lab-created diamonds are made: Chemical Vapor Deposition (CVD) and High Pressure High Temperature (HPHT).
CVD Diamonds
How They're Made:
CVD diamonds form in a vacuum chamber, departing from the immense pressure in the Earth’s depths. Hydrocarbon gas interacts with a diamond seed plate, and microwave energy transforms it into plasma, allowing carbon molecules to bond with the seed plate’s lattice.
Pros and Cons:
- Advantages: Compact, lightweight equipment with real-time monitoring capabilities.
- Challenges: Striation-related transparency issues, color discrepancies, and often requiring post-growth treatments.
Quality Considerations:
CVD diamonds may show transparency challenges and color issues, necessitating additional treatments.
HPHT Diamonds
How They're Made:
HPHT uses immense pressure and high temperatures, simulating conditions below the Earth’s crust. A metal catalyst and graphite create an environment for diamond growth, with carbon atoms bonding layer by layer to a seed plate.
Pros and Cons:
- Advantages: Yields pure, transparent diamonds without post-growth treatments.
- Challenges: Substantial equipment and energy consumption, potential for blue nuances, and gray tinges.
Quality Considerations:
HPHT diamonds are grown in a single, uninterrupted step, minimizing striation-related concerns.
CVD vs. HPHT: Market Dynamics
Pricing Dynamics:
CVD diamonds, due to smaller setups, often have a cost advantage. The surge in new CVD growers has increased supply but led to lower-quality diamonds entering the market. HPHT growers stabilize prices with higher investments.
Environmental Considerations:
Sustainability debates center around electricity consumption. Some CVD growers opt for renewables, but the overall impact on communities differs from the natural diamond industry.
Authenticity of Lab-Grown Diamonds?
Yes, lab-grown diamonds are real diamonds. They possess the same chemical composition as natural diamonds, consisting of pure carbon arranged in a crystal lattice structure. What sets them apart is their origin; lab-grown diamonds are created in controlled environments, while natural diamonds are formed deep within the Earth over millions of years.

The Nature of Lab-Created Diamonds
The term “synthetic” can be misleading. Lab-created diamonds are indeed created through advanced technological processes, but they are not “fake” diamonds. They share the same physical and chemical properties as natural diamonds. The term “synthetic” is often used to describe their man-made origin.
Visual Purity: Lab-Grown vs Natural Diamonds
Lab-grown diamonds are virtually indistinguishable from natural diamonds to the naked eye. They exhibit the same brilliance, fire, and sparkle. Gemologists often use specialized equipment to differentiate between the two. However, for most consumers, the visual appeal of lab-grown diamonds is identical to that of natural diamonds.
Cost Considerations
One of the significant advantages of lab-grown diamonds is their cost-effectiveness. On average, lab-grown diamonds are priced significantly lower than natural diamonds of the same size and quality. This affordability allows buyers to acquire larger or higher-quality stones for their budget.
Investment Potential
The long-term value of lab-grown diamonds can be a topic of debate. While they are a more budget-friendly option, they may not hold or appreciate in value to the same extent as natural diamonds. The market for lab-grown diamonds is still evolving, and their value may be influenced by factors like technological advancements and changing consumer preferences.

Lab-Grown Diamonds and Ethical Responsibility
Lab-grown diamonds are often seen as a socially responsible choice. They bypass many of the ethical concerns associated with traditional diamond mining, such as environmental impact, labor practices, and conflicts related to “blood diamonds.” Many consumers are drawn to lab-grown diamonds for their ethical and sustainable qualities.
Advantages of Lab-Grown Diamonds
- Ethical Sourcing: Lab-grown diamonds are considered more ethical as they do not involve the environmental and social concerns associated with traditional diamond mining, such as habitat disruption and labor exploitation.
- Environmentally Friendly: The process of creating lab-grown diamonds typically has a lower carbon footprint compared to mining, making them a more sustainable choice.
- Cost-Effective: Lab-grown diamonds are often more affordable than their natural counterparts, allowing buyers to get larger or higher-quality stones for their budget.
- Traceability: Many lab-grown diamond brands provide detailed information about the diamond’s origin and production process, offering transparency to consumers.
- Purity and Quality Control: Lab-grown diamonds can be produced with fewer impurities, resulting in exceptional clarity and quality.
Where to Buy Lab-Grown Diamonds
Online Retailers
Numerous online retailers specialize in lab-grown diamonds, offering a wide range of shapes, sizes, and qualities. Some popular online options include Whiteflash, James Allen, Blue Nile, and Adiamor.
Physical Jewelry Stores
Several brick-and-mortar jewelry stores now carry lab-grown diamonds alongside their natural diamond offerings. These stores provide an opportunity to see and compare lab-grown diamonds in person.
Direct from Manufacturers
Some manufacturers and diamond producers sell lab-grown diamonds directly to consumers. This can be an option for those looking for a more customized experience.
Custom Jewelers
Many custom jewelers are open to working with lab-grown diamonds to create unique and personalized pieces of jewelry.
Final Thoughts
Lab-grown or lab-created diamonds offer a real and visually identical alternative to natural diamonds. As the lab-grown diamond market matures, understanding CVD and HPHT distinctions is crucial. Each method influences transparency, color, and pricing. When purchasing, selecting a reputable and knowledgeable merchant ensures a brilliant and ethically sourced lab-grown diamond. When deciding where to purchase lab-grown diamonds, consider your preferences, budget, and the level of customization you desire to make an informed choice that suits your needs.
