Frequently Asked Questions

What are Lab Grown Diamonds?  

Lab grown diamonds are man-made diamonds that are chemically, physically, and optically identical to diamonds originating from nature. Both have the same chemical composition and atomic structure, producing the very same durability, fire, and sparkle. Laboratory grown diamonds are a testament to the use of technology and human achievement.

How do Lab Grown Diamonds grow? 

Lab grown diamonds utilize a Chemical Vapor Deposition (CVD) process or a High Pressure High Temperature (HPHT) method that cause carbon atoms to crystallize into the structure that renders them harder than any other form of carbon and harder than any other material. Both processes require advanced technological equipment and both produce rough diamonds that are then cleaned, cut, and polished in the very same way that naturally-occurring, mined diamond rough is processed.

What Growth Process Does True Origin™ Utilize? 

Our product involves a combination of both CVD and HPHT.

What are Diamond Seeds?  

Diamond growth can be initiated only when a pre-existing diamond seed or a sliver of diamond substrate is present for the carbon atoms to attach to and “learn” the diamond’s strong tetrahedral crystal lattice. The “seed” essentially serves as a blue print for the crystallization process as carbon atoms stack one-by-one on the carefully selected seed. 

How are Lab Grown Diamonds Graded? 

Lab grown diamonds are graded to the same carat, clarity, color, and cut specifications as mined diamonds and they can be accompanied by the same type of Diamond Grading Reports written by leading independent gemological institutes and certified appraisers.

Why is “Lab Grown Diamonds” the preferred term for man-made diamonds?

“Lab Grown” most accurately describes the man-made diamond production process in which the crystal structure is grown from the seed diamond. Lab grown diamonds are the result of an extemporaneous crystallization process rather than a synthesis of compounds. Lab grown diamonds are unequivocally diamonds with the same physical, chemical, and optical properties as earth mined diamonds.

Why Choose a True Origin™ Lab Grown Diamond? 

True Origin™ is a member of the International Grown Diamond Association (IGDA), the leading global platform dedicated to representing and promoting lab grown diamonds. IGDA members adhere to a strict Code of Conduct toward ethical trade responsibilities, and uphold a progressive Best Practices Agreement regarding human rights and environmental issues. The True Origin™ Lab Grown Diamonds state of the art manufacturing facility is owned and operated by True Origin™, ensuring factory direct pricing, reliable supply, and the dependable customer service our clients have come to expect.  

How is True Origin™ Lab Grown Diamond Rough handled in the laboratory and processed into stones?

Once the lab grown diamond rough is large enough to be extracted from the machine, the stone is identified as lab grown. The rough then goes through the same analysis and review as nature made rough. It is analyzed by highly skilled cutters to plan for the best facets and cuts to yield the stones with the best proportions and symmetry. 

The lab grown rough is cut in a responsible, controlled facility. The stones are then polished and inspected. Each stone is packaged carefully with full disclosure of its origin as a lab grown diamond. 

What are the True Origin™ Lab Grown Processing Protocols?

  • Each stone is inspected and tested. It is then stored in a separate and secure vault. 
  • Production of finished jewelry featuring lab grown diamonds is conducted in a controlled environment and within a separate facility. Tight control of production insures only lab grown diamonds are being utilized.  
  • Finished jewelry is identified as True Origin™. It is tested, inventoried and shipped in distinct packaging with full disclosure of lab grown diamonds. 
  • Should a True Origin™ Lab Grown Diamond piece be returned, it is immediately tested for proper identification of stones featured. Lab grown diamond product is then stored separate from other items. 
  • Tight processing controls, full disclosure in each step of traceable chain of custody, as well as dedication to transparency ensures each lab grown diamond is of known origin.

How are Fractional Weights of Diamonds determined?

Diamonds are measured by weight in a unit named "carats" (ct). The weight of a diamond is often represented as either a decimal or a fractional value. When represented as a fraction, a range of decimal values is associated with common diamond fractional weights. A table of those decimal ranges and their corresponding fractional weights is shown below.
