America's Watchdog Counterfeit Gold Bars and Silver Bullion

“According to our research Chinese counterfeiters are flooding the US, and Europe with very high quality fake US silver dollars, gold coins, gold bars – you name it. We would call this a disaster for the investor, and our big fear is there are probably tens of thousands of investors in the United States, who have been duped.”

Gold and Money discuss the use of Ultrasound to verify gold bullion and silver bars.

James Turk recommends ultrasound to avoid counterfeit gold and silver bullion

“Ultrasonics is an advanced technology providing a simple solution to a complex problem. I think it would be impossible to put an insert into a gold bar that you couldn’t detect with ultrasonics.”

Olympus develops advanced ultrasound equipment in the fight against counterfeit metals

Olympus develop ultrasound equipment to test counterfeit gold bars and silver bullion

“Gold bullion bars have been fraudulently adulterated through the insertion of slugs of inexpensive base metal of similar density. These insertions are difficult or impossible to detect through weighing, radiography, or X-ray fluorescence, so some precious metals processors have resorted to drilling or cutting bars to verify integrity. However a simple ultrasonic test can quickly and reliably locate inserts with no need to drill, cut, or otherwise alter the bar.”



The precious metals investment sector is an easy target for sophisticated industrial scale counterfeiters, criminal organizations and scammers. Low cost tungsten is nearly the same density as gold. Copper, lead and other base metal alloys can duplicate the density of silver. Traditional non-destructive test methods by density and X-ray spectrometry are incapable of detecting fake bullion and bars with thick gold or silver plating. The ultrasound technology of GT-Ultra is the most affordable and simplest non-destructive method to test gold bullion and silver bars in your home.
