Description

Buy a 1-ounce gold bar – 31.1 g

The 1-ounce gold bar, containing 31.1 grams of fine gold, is a particularly popular format for investing in physical gold. Compact and easily tradable, it allows investors to hold a standardized amount of investment-grade gold.

Specifications of the 1-ounce bar

  • Purity: 999.9‰
  • Metal: fine gold
  • Format: investment bar

Why buy a 31.1-gram gold bar?

The 1-ounce size is an international standard in the gold market. Its size allows investors to invest in a significant amount of gold while retaining greater flexibility than with a large bar.

Its purity of 999.9‰ means it is composed almost entirely of fine gold.

An internationally recognized format

The troy ounce is the standard unit of measurement used in international precious metals markets. The ingots offered may come from various recognized manufacturers and are identified by their weight, purity, and—depending on the model—a serial number or certificate.
