Our Technology
Grown in Weeks, Not Eons
Buyers increasingly ask about origin. Here is how the two compare — and exactly where we stand.
Lab-Grown Diamonds
HPHT • Precision Manufacturing
- Formation
- Grown in 3–10 weeks under high pressure high temperature technology (HPHT)
- Composition
- Chemically, optically and physically identical to mined stone
- Grading
- Graded on the same universal 4Cs, by the same laboratories
- Supply
- Consistent supply, so repeat parcels stay true to spec
- Manufacturing
- Produced using controlled technology, allowing manufacturing to respond to specific market requirements.
Mined (Natural) Diamonds
Not part of our current range
- Formation
- Formed 1–3 billion years ago in the earth’s mantle
- Composition
- Chemically identical — same crystal structure, same carbon
- Grading
- Graded on exactly the same 4Cs, by the same laboratories
- Supply
- Finite supply drives higher, more volatile price points
- Manufacturing
- Dependent on naturally occurring rough diamonds recovered through mining.
Bhargovi Gems manufactures lab-grown diamonds exclusively. This comparison is published for buyer education, not as a sales position.
