Frequently Asked Questions
1. What is lab-grown diamonds?
a) Lab-grown diamonds are real diamonds that are created in a laboratory rather than being mined from the earth.
b) Two methods of creating lab-grown diamonds:
HPHT (High Pressure, High Temperature):
Mimics the conditions deep underground where natural diamonds form—carbon is subjected to extremely high pressure and heat until it crystallizes into diamond.
CVD (Chemical Vapor Deposition):
Uses a chamber filled with carbon-rich gas; carbon atoms slowly accumulate on a substrate, growing into a diamond layer by layer.
2. Are lab diamonds real diamonds?
Yes, lab-grown diamonds are REAL DIAMONDS. They have the same chemical composition, crystal structure, and physical properties as natural diamonds (pure carbon arranged in a cubic crystal lattice), so they look and perform exactly the same in terms of sparkle, hardness, and durability.
3. Lab-grown Diamonds V.S. Natural mined Diamonds
| Category | Lab-Grown Diamonds | Natural Diamonds |
|---|---|---|
| Origin & Formation | Created in a controlled laboratory environment using technological processes such as High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD). | Formed by nature deep within the Earth over billions of years, then brought to the surface through volcanic eruptions. |
| Chemical Composition | 100% crystallized carbon, possessing the identical chemical and physical structure as natural diamond. | 100% crystallized carbon, with a crystal structure formed by nature. |
| Optical & Physical Properties | Visually, optically, and physically identical to natural diamonds; require specialized equipment from gemological laboratories for identification. | Visually, optically, and physically identical to lab-grown diamonds; require specialized equipment from gemological laboratories for identification. |
| Ethical Sourcing | Have a traceable origin and are guaranteed conflict-free by their controlled production process. | The modern natural diamond industry adheres to strict protocols (e.g., the Kimberley Process) to ensure conflict-free sourcing. |
| Environmental Considerations | Production has a different environmental profile, primarily associated with energy consumption, but avoids large-scale land disturbance. | Traditional mining has evolved; many major players now implement comprehensive environmental management and land rehabilitation plans. |
| Grading & Certification | Graded to the same standards using the 4Cs by leading institutes like GIA and IGI, which clearly disclose the lab-grown origin. | Graded using the universal 4Cs system (Cut, Color, Clarity, Carat) by leading independent gemological institutes like GIA and IGI. |
| Rarity & Value | Accessible and can be produced to meet demand, offering significant value. | Rare and finite, as their supply is limited by what nature has created. Value is tied to geological rarity. |
4. Does Lab Grown Diamond come with certification?
a) YES, Lab-grown diamonds have the same type of certificates as natural diamonds.
b) The main grading labs for lab-grown diamonds are:
GIA (Gemological Institute of America): One of the most respected labs worldwide. Modern GIA reports for lab-grown diamonds now use the same scale as for natural diamonds.
IGI (International Gemological Institute): Very popular for lab-grown stones, especially in the U.S. and Asia. Known for fast turnaround and detailed grading reports.
5. Why choosing Lab Grown Diamonds
a) Ethically and environmentally friendlier than natural diamonds since they avoid mining.
b) More accessible cost: lab-grown diamonds are usually cost 30%-40% less than natural diamonds.
