The 1 trillion VND diamond ring (equivalent to more than 40 million USD) is a one-of-a-kind masterpiece, typically only appearing at prestigious auction houses such as Sotheby’s or Christie’s. In Vietnam, this figure is associated with Ms. Nguyễn Phương Hằng’s 45-carat ring; however, the actual value of these assets depends entirely on GIA certification, Type IIa clarity, and ownership history.
Let Jemmia Diamond analyze the factors that create the "trillion-dong" price tag and the world’s rigorous appraisal process in the article below!
Why can a diamond ring cost up to 1 trillion VND?
For a ring to reach a million-dollar value threshold, the center diamond must possess extremely rare geological characteristics, far beyond ordinary jewelry standards:
- Type IIa clarity: This is a type of diamond that contains almost no nitrogen impurities, accounting for only 1-2% of global production. This characteristic creates absolute transparency like pure water (Water-clear).
- Rare color (Fancy Color): Diamonds graded Fancy Vivid (Pink, Blue, Green) or D color (Perfect white) in large sizes always increase in value progressively by weight.
- Weight (Carat): Usually must reach from 30 carats to over 50 carats for a single center stone.
- Origin (Provenance): The value skyrockets if the stone was mined from legendary closed mines such as Golconda (India) or was once owned by royalty.

Comparing Ms. Phương Hằng’s 45-carat ring with world records
Valuing the 45-carat ring at 1 trillion VND needs to be placed in context with international treasures that have been verified through public auctions:
| Name of masterpiece | Weight | Characteristic | Converted value (VND) |
| Pink Star | 59.60ct | Pink (Fancy Vivid Pink) | ~1,780 Billion |
| Oppenheimer Blue | 14.62ct | Blue (Fancy Vivid Blue) | ~1,437 Billion |
| Ms. Phương Hằng’s ring | 45.00ct | White (D Color) | ~1,000 Billion |
| The Prince | 34.65ct | Pink (Fancy Intense) | ~980 Billion |
Note: Ms. Phương Hằng’s 1 trillion VND price is a personal asking price, including brand value and charitable purposes, and has not been verified through international auction.

Value verification process for million-dollar diamond rings
For assets worth as much as an entire business, appraisal cannot rely on subjective judgment but must go through a strict process:
- International GIA certification: It is mandatory to have a grading report from the Gemological Institute of America to confirm the 4Cs. Without this certificate, all figures about value have no commercial basis.
- Additional Type IIa assessment: Determines that the stone belongs to the purest diamond group in the world, guaranteeing its long-term investment value.
- International trading floors: These items are usually only liquid in Geneva, Hong Kong, or New York.
- Operating costs: Insurance, secure storage, and maintenance fees for a 1 trillion VND ring can cost billions of VND each year.
