9999 and 24K Gold: Are They the Same?
In short, yes. 9999 gold, 999 gold, and 24k gold are the most highly purified gold, usually in the form of bullion bars.24k gold is purer than any gold you would typically encounter in a jewelry store. Because gold is a soft, scratch-prone metal, gold jewelry is generally made from alloys to ensure higher durability.
- 23k gold: An alloy with 95.9 percent gold content, found in some foreign jewelry.
- 22k gold: A more durable alloy containing approximately 92 percent gold. This alloy appears in some fine gold jewelry and American gold eagle coins.
- 21k gold: A less-common alloy of about 87.6 percent gold. Some vintage jewelry has this type of gold content.
- Rose or red gold: An 18k gold alloy that contains 25 percent copper and 75 percent gold.
- Black gold: An 18k alloy of 75 percent gold and 25 percent cobalt.
- Green gold: also known as electrum, this natural alloy contains about 27 percent silver and 73 percent gold.
- White gold: A 14k, or 58.5 percent alloy that combines gold with nickel, palladium, or manganese.
Why is 9999 Gold Usually Called 24k?
There are two systems to define gold purity: the well-known karats and the millesimal fineness system, which establishes the purity of gold, silver, platinum, and other precious metals by stating the pure metal’s parts per thousands in an alloy.24-karat, or 24k gold, counts as 9999 (i.e., 99.99 percent) in the millesimal system. 18k gold is 750 (75 percent) gold under the millesimal system.
A single gold karat equals 1 part out of 24, or 4.1667 percent. The karat system goes back to the medieval mark, a gold coin that weighed 24 karats. Since pure gold coins would be too soft for everyday use, metals like copper made up part of the karatage, or coin weight. The proportion of gold in the coin determined its karatage. For example, a coin containing three parts gold and one part copper was an 18-karat coin.
How to Spot Fake 24k Gold?
Throughout history, crooks have tried to pass counterfeit gold or gold-plated items as 24 karat gold. Fortunately, there are several ways to make sure you buy genuine pure gold:- Look at the gold bar through a magnifying glass. Discoloration or excessive shine are signs of fake gold.
- Compare the bar’s weight to a same-sized bullion bar from a trusted source. The two bars should weigh precisely the same.
- Handle the bar with your bare clean hands for a couple of minutes. Gold is an inert metal and shouldn’t react with your skin. If you notice a skin reaction, you’re likely holding a counterfeit gold bar.
- Hold a high-strength magnet near the gold bar. If the bar attracts the magnet, you’re dealing with fake gold or a gold alloy.
- Sprinkle the bar with a few drops of white vinegar. If the metal changes color, it’s fake gold.
Are Bullion Bars 99.99 Percent Gold?
Most bullion bars from reputable sources are 9999 (99.99 percent) or 999 (99.9 percent) gold. We do not recommend investing in gold bars that contain less than 99.5 percent gold. A gold bullion bar should feature its weight, purity, and manufacturer’s name in clear stamping upon its face.When exploring investment-quality gold, it is essential to distinguish between bullion bars and bullion coins. While bullion coins look attractive and often have numismatic value, investors typically get less gold for their money when they buy coins.
