Heraeus 1 t/oz gold bar

The 1 troy ounce (31.1 gram) gold bar from Argor-Heraeus is a popular choice among investors thanks to Swiss precision and the global trust this producer enjoys. Argor-Heraeus is renowned for its exceptional quality standards and has been a leading name in the precious metals industry for decades. The refinery produces internationally recognized LBMA-certified gold bars made of 999.9 pure (24-carat) gold. Each 1 troy ounce gold bar features a unique serial number and is delivered in a plastic blister pack that also serves as its official certificate of authenticity.

One troy ounce equals 31.103 grams and originates from the medieval French city of Troyes, then an important trading hub. This weight standard is used worldwide to quote the gold price and remains one of the most recognized measurements in the precious metals market.

Argor-Heraeus has been accredited by the LBMA (London Bullion Market Association) since 1961 and is part of a select group of five refineries authorized to advise the LBMA.

Design & Manufacturer

The bar features the producer’s name Argor-Heraeus, its weight (1 troy ounce), purity (999.9), and a unique serial number. This number corresponds to the packaging, which also serves as the certificate of authenticity. The bar also bears the inscription ‘Melter Assayer’, confirming that its purity and weight have been officially verified and guaranteed by the Argor-Heraeus assayer. The 1 troy ounce gold bar is a minted bar, meaning it is struck with a unique die for precise detailing.

The company leads in responsible sourcing and certification and, in addition to LBMA recognition, is accredited by COMEX (New York), the Chicago Mercantile Exchange (CME), and the Tokyo Commodity Exchange (TOCOM).

1 troy ounce

One troy ounce equals 31.103 grams. The term originates from the French city of Troyes, which was a major medieval trading center where the need for a standardized measurement for precious metals arose. Since then, the troy ounce has become the global standard for gold and silver. The international gold price is quoted in U.S. dollars per troy ounce. Note: the troy ounce differs from the regular ounce used for everyday goods, which weighs only 28.35 grams.
