Lab-grown diamonds are chemically, physically, and optically identical to mined diamonds, offering the same brilliance and durability but at a significantly more accessible price point. Created in a controlled environment using advanced technology, they are a sustainable and ethical alternative to traditional mining.
Lab-grown diamonds are diamond crystals produced in controlled CVD or HPHT growth systems rather than extracted through mining. Depending on growth route, crystal quality, cutting and finishing, they can be supplied as industrial diamond materials or as gem-quality stones for jewelry production.
CVD and HPHT are different diamond growth routes. Neither label alone determines whether a stone or material is appropriate for a buyer's project.
CVD diamonds are grown from carbon-containing gases in a controlled deposition environment. The category includes both gem-quality diamonds and technical CVD materials, so the intended use must be defined clearly.
Separate jewelry-grade CVD stones from industrial CVD materials
Specify loose-stone 4C requirements or technical material parameters
Use the dedicated CVD page for growth-method purchasing terms
HPHT diamonds are grown under high-pressure and high-temperature conditions. Jewelry buyers should distinguish HPHT-grown diamonds from post-growth HPHT treatment terminology.
Confirm whether the request refers to growth method or treatment
Provide carat, shape, color, clarity and cut requirements
Use the dedicated HPHT page for product-specific inquiries
Custom requests can be evaluated based on the jewelry drawing or design, required shapes, calibrated dimensions, carat range, color, clarity, cut, matching tolerance and production quantity. Use the custom diamond supply page for this requirement.
A lab-grown diamond is a diamond crystal produced in a controlled growth system using CVD or HPHT technology rather than extracted through mining. Product grade, dimensions, cutting and finishing determine whether it is suitable for industrial or jewelry applications.
The category includes industrial lab-grown diamonds, gem-quality loose diamonds, CVD and HPHT product routes, and customized diamond supply for jewelry manufacturing.
Both belong to the lab-grown diamond category, but they use different growth environments. Buyers should select according to the intended application, required size, quality, color, shape, processing and documentation—not assume that one method is universally better.
Yes. Industrial product routes include lab-grown diamond and CVD diamond materials for technical uses such as precision cutting, grinding, thermal management and optical applications.
