Buying gold is easy to get fake ones, so buying digital gold is more convenient.

Many gold shops across the country have been scammed! A large number of online merchants openly sell rhenium powder, claiming "20% to 23% rhenium powder mixed in, spectral analyzers can't detect it."
Recently, some short video creators claimed that a metal powder called "rhenium" is mixed into gold and melted at high temperature; after cooling, not only does the gold's weight increase, but neither the naked eye nor machines can detect any difference. The purity of rhenium-doped gold can reach up to 99.9%. Is this true? Some consumers and gold recyclers have reported buying "fake gold" mixed with rhenium. How can you tell if gold is mixed with rhenium?
Last year, police in Changxing County, Huzhou City, Zhejiang Province, uncovered a rhenium gold forgery case. A gold shop operator received a gold necklace, and the other party claimed it was made from previously purchased gold.
The operator followed the usual gold purchasing process, first inspecting with the naked eye and finding no abnormalities, then conducting a fire test, which also showed no discoloration. After confirming it was genuine, the operator bought the necklace at the then-market price of over 800 yuan per gram.
That afternoon, a senior staff member at the gold shop noticed during an inspection that the cross-section of the necklace was rough, suspected to be fake gold, and reported the case.
After receiving the report, the police identified a rhenium gold scam ring.
Investigation revealed that the group's financial transactions spanned multiple provinces, with several gold shop operators transferring money to them, and many victims.
Eventually, police arrested two core members of the scam gang at a gold processing shop in Wuhu, Anhui Province.
The reporter found that on some online platforms, many merchants openly sell rhenium powder, with product descriptions including "fire treatment, spectral analysis, gold alloying," openly selling counterfeit materials.
Merchants claim that mixing 20% to 23% rhenium powder can bypass common spectral detection methods on the market.
Experts explain that rhenium and gold have similar atomic numbers, with spectral peaks overlapping significantly, and their densities are close, making it difficult to distinguish through conventional fire testing, weighing, or water displacement methods.
So, how can you tell if gold is fake and mixed with rhenium?
Experts advise choosing reputable brand stores when buying gold, requesting invoices and quality inspection certificates; prefer products priced per gram to reduce fraud risk; suspected fake gold can be sent to professional institutions for testing and identification. (CCTV News)$XAU
