Overview

Phu Nhuan Jewelry (PNJ) plans to hire an international independent auditor to review its diamond quality and processes after a former director of its subsidiary was prosecuted for diamond smuggling. The stock dropped 6.3% and has lost nearly 35% of its market value since the news broke.

Key Facts

  • PNJ’s board approved hiring international independent units for auditing, inspection, and consulting on diamond quality and processes.
  • The decision was signed by Chairwoman Cao Thi Ngoc Dung and tasked CEO Phan Quoc Cong with implementation.
  • Former director of PNJ’s subsidiary P-Lab, Dang Ngoc Thao, was prosecuted for involvement in a diamond smuggling ring.
  • PNJ stock closed at VND 40,900 on July 16, down 6.3% for the day.
  • The stock has lost nearly 35% of its market value, erasing about VND 11,400 billion in market capitalization.
  • Foreign investors net sold nearly VND 148 billion in PNJ shares on July 16.
  • PNJ Chairwoman stated that smuggled diamonds did not enter PNJ’s system; all imports are through official channels from Thailand and Hong Kong.

What Happened

PNJ’s board of directors approved a plan to hire international independent units to conduct a comprehensive review of the company’s diamond quality and processes. The review will include independent inspection and certification of product quality (including diamonds and jewelry), an audit of the entire process from import to production to sales, and a risk management assessment by an independent consultant.

Chairwoman Cao Thi Ngoc Dung told VnExpress that a third party is needed to identify internal shortcomings. “Sometimes insiders find it hard to see their own blind spots,” she said. The move comes two weeks after former P-Lab director Dang Ngoc Thao was prosecuted for diamond smuggling. Dung emphasized that the smuggled diamonds did not enter PNJ’s system and that all imports are through official channels.

Market Context

PNJ shares closed at VND 40,900 on HOSE on July 16, down 6.3% for the session with trading volume exceeding VND 600 billion. Foreign investors were net sellers of nearly VND 148 billion. The stock has lost nearly 35% of its market value since the scandal emerged, wiping out approximately VND 11,400 billion in market capitalization and causing PNJ to lose its billion-dollar company status.

Strategic Significance

PNJ’s decision to hire an international auditor signals a proactive effort to restore investor confidence and strengthen corporate governance after a reputational blow. The move addresses concerns about internal controls and transparency in the diamond supply chain, which is critical for a leading jewelry retailer. If the audit confirms PNJ’s processes are clean, it could help rebuild trust. However, the scandal highlights vulnerabilities in subsidiary oversight, and the company’s long-term premium valuation may remain under pressure until independent verification is complete.

What to Watch

  • Completion and publication of the international audit results.
  • Any further legal developments in the smuggling case involving former P-Lab director.
  • PNJ’s Q2 2026 earnings report for signs of operational impact.
  • Foreign ownership trends and net buying/selling activity.
  • Any changes in PNJ’s dividend policy or share buyback plans to support the stock.
