1. What is Lab Grown Diamond?

A Lab Grown Diamond is a genuine diamond cultivated in a laboratory by simulating the natural formation environment of mined diamonds. It shares the exact same chemical composition (carbon), crystal structure, as well as physical and optical properties with natural diamonds.

Lab grown diamonds are not moissanite, cubic zirconia (CZ) or other diamond simulants; they are authentic diamonds.

2. What are the differences between HPHT Lab Grown Diamond and CVD Lab Grown Diamond?

We supply both HPHT (High Pressure High Temperature) and CVD (Chemical Vapor Deposition) lab grown diamonds.

Features of HPHT Diamonds

• It replicates the formation environment of natural diamonds. 
• Relatively fast growth rate. 
• Suitable for producing high-grade white diamonds and fancy colored diamonds. 
• Widely applied in items with high color grades.

Features of CVD Diamonds

• Adopts advanced chemical vapor deposition technology. 
• High crystal purity.
• Excellent consistency in dimension .
• Especially ideal for large carat diamonds with high clarity.

Diamonds produced via both technologies are real diamonds and can be certified by internationally recognized professional gemological institutions.

3. Are lab grown diamonds real diamonds?

Yes. Lab grown diamonds are genuine diamonds instead of counterfeits or imitations. Professional testing equipment can identify their origin (natural or lab created), yet cannot deny their identity as diamonds.

4. What is the difference between lab grown diamonds and natural diamonds?

The main distinctions are listed below:
• Different origins: Natural diamonds are excavated from underground mineral deposits, while lab grown diamonds are manufactured in laboratories.
• Different formation periods: Natural diamonds take billions of years to form, whereas lab grown diamonds are generally produced within several weeks.
• Different price points: Lab grown diamonds feature more cost-effective pricing compared to natural diamonds.
• Identical appearance and performance: They cannot be distinguished by the naked eye, with the same hardness (Mohs scale 10), fire and optical characteristics.
