What Are Lab-Grown Diamonds?
Lab-grown diamonds are real diamonds produced in controlled laboratory environments using advanced diamond-growth technology. They have essentially the same chemical composition, crystal structure and fundamental optical properties as natural diamonds. Like natural diamonds, their appearance and quality vary according to their individual characteristics.
Lab-grown diamonds are commonly produced using two methods: Chemical Vapor Deposition (CVD) and High Pressure High Temperature (HPHT). Their growth origin differs from that of natural diamonds, which form through geological processes within the Earth.
At Lavish Lab-Grown Diamond, we focus on B2B diamond sourcing and supply, helping professional buyers communicate their requirements for shapes, carat weights, color, clarity, growth method and certification.
CVD — Chemical Vapor Deposition
CVD diamonds grow as carbon-containing gases are introduced into a specialized vacuum chamber, depositing carbon atoms layer-by-layer onto a diamond seed crystal under low pressure.
HPHT — High Pressure High Temperature
HPHT diamonds are grown under conditions of high pressure and high temperature that support diamond crystal formation, replicating the intense physical conditions required for diamond growth.
Lab-Grown Diamonds vs Natural Diamonds
Both are diamonds, but their origins differ. Understanding that distinction helps businesses communicate accurately with their customers and make informed sourcing decisions.
| Comparison | Lab-Grown Diamonds | Natural Diamonds |
|---|---|---|
| Origin | Grown in a controlled laboratory environment | Formed through natural geological processes within the Earth |
| Basic composition | Crystalline carbon | Crystalline carbon |
| Crystal structure | Diamond crystal structure | Diamond crystal structure |
| Production timeline | Grown over a much shorter period under controlled conditions | Formed over geological timescales |
| Growth methods or processes | Commonly CVD or HPHT | Natural geological formation |
| Identification | Specialized gemological testing may be used to identify laboratory growth | Gemological examination may identify natural origin |
| Certification | Eligible stones may be accompanied by grading reports from recognized laboratories | Eligible stones may be accompanied by grading reports from recognized laboratories |
| Sourcing considerations | Availability, specifications, growth origin, documentation and price | Availability, specifications, natural origin, documentation and price |

From Carbon Seed to Finished Diamond in 4 Precise Steps
Discover the key stages behind lab-grown diamond production, from crystal growth to final inspection and grading.
CVD Diamond Growth
Lab-grown diamonds can be produced using Chemical Vapor Deposition (CVD), where carbon-containing gases are used to grow diamond crystal layers on a diamond seed inside a controlled chamber.
