Gold-Clad Tungsten Jewelry Fraud: Using Fakes to Defraud Gold Shops of Real Currency

Who Gets Targeted

Victims are primarily individual gold shops, jewelry recyclers, and private gold dealers in third- and fourth-tier cities and towns. These groups are generally sensitive to the profit margins of gold recycling and often possess rudimentary testing equipment. Furthermore, scammers exploit their sympathy by claiming urgent needs for cash, such as selling heirloom wedding jewelry or needing quick liquidity, causing merchants to lower their guard. Many merchants, eager for business, skip deep testing and complete purchases based solely on appearance and simple instruments, ultimately leading to massive financial losses.

骗局怎么运作

• Criminal gangs purchase tungsten blocks, gold foil, and rhenium metal through illegal channels in advance. Using pressing, gold-plating, and welding techniques, they create gold-clad tungsten or gold-clad rhenium jewelry. The outer layer is less than 1mm of real gold, while the core is tungsten or a tungsten-rhenium alloy. The weight is almost identical to pure gold of the same volume, with a unit cost of only a few dozen yuan. The appearance and feel are indistinguishable from real gold, and some high-end fakes can even pass standard handheld XRF (X-ray fluorescence) spectrometer tests.
• Gang members travel to various gold shop clusters and town markets, approaching merchants with excuses like 'urgent need for cash at home,' 'selling idle wedding jewelry,' or 'temporary collateral for turnover.' They falsely claim the gold bracelets or bars are 999 pure gold and demand high-price recycling or collateral, often proactively showing forged purchase receipts or appraisal certificates to increase credibility.
• When merchants request testing, gang members use excuses such as 'I'm in a hurry,' 'I only want to sell a small part and keep the rest as a memento,' or 'testing will damage the jewelry and affect resale.' They only allow the merchant to cut a small corner for testing, keeping the rest in their possession. Some gangs even tamper with the merchant's testing equipment in advance or insist on using their own simple testing tools to avoid exposure.
• After the merchant completes a simple test and mistakenly believes the gold is real, they pay the full price. Once the gang receives the payment, they immediately flee to the next target city via long-distance bus or ride-hailing services, using fake identities and avoiding hotel registration. By the time the merchant melts the gold and discovers the tungsten core, the gang is long gone.
• Some sophisticated gangs use a 'long-line fishing' tactic: they sell real gold jewelry in the first transaction to build trust. Once the merchant's guard is down, they sell the fakes in the second transaction, sometimes even promising to 'buy it back at the original price in a week.' After receiving the buy-back payment, they cut off all contact, further lowering the merchant's vigilance.

红旗信号（看到这些快跑）

• 🚩 The gold jewelry offered for sale or collateral is unusually shiny with no visible wear or scratches, yet the seller is in a rush to sell it at more than 10% below market price;
• 🚩 The seller explicitly refuses high-temperature melting tests, agreeing only to cut a small corner or perform surface spectral analysis, while demanding to keep the rest, or even threatening the merchant by claiming 'damaging the jewelry requires compensation';
• 🚩 The surface reading on a handheld spectrometer is normal, but the internal reading after cutting is abnormal, or the seller insists on only testing the exterior and forbids testing the cross-section;
• 🚩 The same gang members appear multiple times in the same area within a short period (1-2 weeks), with each transaction amount near the local limit for gold recycling;
• 🚩 The seller cannot provide complete purchase receipts for the jewelry, provides vague identity information, uses fake names or phone numbers during registration, or refuses to register altogether.

真实案例

• In May 2026, a gold shop owner in Liaocheng, Shandong, purchased a pair of bracelets. Upon melting them, they discovered a white metal core and reported it to the police. Two mobile suspects were arrested. The gang had previously committed 13 crimes across Shandong and Hebei, involving over 2.3 million yuan. The fake jewelry used tungsten-core technology and was indistinguishable from real gold.
• In August 2026, Ningbo police in Zhejiang arrested 9 suspects across provinces, cracking a series of gold-clad tungsten fraud cases. The gang operated 42 times across six provinces—Zhejiang, Jiangsu, Anhui, Jiangxi, Fujian, and Shanghai—defrauding gold shops of over 5 million yuan. Some fake gold bars were doped with rhenium, matching the density of pure gold and rendering them undetectable by standard instruments.

• In October 2025, Hangzhou police received reports from multiple gold shops that purchased gold jewelry turned out to be fake, with losses exceeding 3.2 million yuan. The gang used 'gold-clad rhenium' technology, which even some professional gold-buying institutions' equipment failed to identify. The case is currently under investigation.
• In May 2024, the Wuhan Intermediate People's Court delivered the first-instance verdict in the 83-ton fake gold case involving Kingold Jewelry. The company used a gold-pledge and insurance-backed model to obtain approximately 20 billion yuan in financing from financial institutions using gold-clad copper, corresponding to about 83.03 tons of pledged gold. The founder was sentenced to life imprisonment, and other defendants received sentences ranging from three years and two months to twelve years.

Official Stance

• On August 12, 2026, the Criminal Investigation Bureau of the Ministry of Public Security issued an 'Emergency Warning on Preventing Gold-Clad Tungsten and Rhenium-Doped Fake Gold Fraud,' advising gold recyclers and jewelry merchants nationwide to stay vigilant and perform melting tests for all gold acquisitions.
• On April 26, 2026, the China Consumers Association issued a 'Gold Consumption Safety Warning,' reminding consumers and merchants not to judge the authenticity of gold solely by appearance or simple instruments, and to report suspicious activities to market regulators and public security organs.
• On October 27, 2025, the Hangzhou Public Security Bureau Anti-Fraud Center issued a notice regarding 6 recent cases of rhenium-doped fake gold fraud in the city. Several professional gold-buying firms were defrauded of over 3 million yuan, and merchants were urged to take precautions.

How to Protect Yourself

• ✅ Strictly enforce high-temperature melting test procedures when acquiring gold. Do not rely solely on surface corner-cutting or handheld spectrometer tests; confirm there are no impurities or discoloration after melting before paying.
• ✅ Require the seller/pledgor to provide complete purchase receipts and identification. Verify identity through official channels and do not purchase gold jewelry of unknown origin.
• ✅ For large-value gold collateral transactions, do not pay the full amount at once. Pay a deposit of about 30% first, and pay the balance only after melting confirms the authenticity to reduce the risk of loss.
• ✅ Join local gold merchant anti-fraud communication groups to receive timely warnings of the latest fraud techniques. If suspicious individuals or jewelry are discovered, call 110 immediately and preserve evidence such as transaction recordings and the other party's identity information.
