Overview
PNJ (Vàng Phú Nhuận) announced that its wholly-owned subsidiary P-Lab will temporarily suspend diamond and gemstone certification services for external customers, focusing only on internal products.

- P-Lab has stopped accepting external certification requests due to capacity constraints and legal risk concerns.
- The former P-Lab director, Đặng Ngọc Thảo, is accused of certifying smuggled diamonds, involving over 28,000 stones.
- PNJ is considering permanently ending external certification services to minimize legal exposure.

- PNJ stock closed at VND 38,150 on July 21, 2026.
- P-Lab was originally established to serve PNJ’s internal needs before expanding to external clients.
What Happened
Two weeks after the smuggling case involving over 28,000 diamonds and the former P-Lab director was made public, PNJ held an unscheduled press conference. CEO Phan Quốc Công stated that P-Lab is now prioritizing internal certification and has temporarily stopped accepting external requests. He explained that the lab is operating at full capacity and that the company is reviewing the business model to reduce legal risks.
PNJ acknowledged that the former director allegedly abused his position to issue certificates for smuggled diamonds. The company noted that P-Lab, like other gemstone labs, did not require customers to prove the origin of stones—a common industry practice. However, after the incident, PNJ is considering permanently halting external certification to avoid potential legal complications if certified assets are later found to be involved in smuggling.
Market Context
PNJ shares closed at VND 38,150 on July 21, 2026, on the HOSE exchange. The company operates in the personal and household goods sector. The smuggling case and subsequent operational changes could affect investor sentiment, as P-Lab’s external certification services were a revenue source and industry support activity. The broader Vietnamese retail sector has been under pressure from regulatory scrutiny and economic headwinds.
Strategic Significance
The decision to suspend external certification reflects PNJ’s focus on risk management and compliance. By limiting P-Lab to internal use, PNJ reduces exposure to legal liabilities from third-party transactions. This move may strengthen the company’s reputation for integrity but could also reduce a revenue stream and limit industry support. Long-term, PNJ may prioritize core jewelry retail operations over ancillary services.
What to Watch

- Any official announcement on permanent cessation of external certification services.
- Regulatory developments in gemstone certification standards in Vietnam.
- PNJ’s stock price reaction and foreign ownership changes.
- Updates on the legal case involving the former P-Lab director.
