5k gold is a low-karat alloy containing only 20.85% pure gold, with the remaining 79.15% being other metals like silver, copper, and zinc. This minimal gold content makes it unappealing to investors and jewelry enthusiasts.
The alloy isn’t magnetic when mixed with non-magnetic metals, but becomes magnetic with ferromagnetic metals like iron or nickel. Due to its high percentage of other metals, 5k gold isn’t hypoallergenic and commonly causes skin allergies.
It’s not used for investment bullion due to low gold content, and jewelry made from 5k gold is extremely rare. No official hallmarks exist for this non-standard alloy.

What is 5k Gold (Definition and Meaning)?
5k gold is a gold alloy that contains approximately 20.85% pure gold, with the remaining percentage being other metals like silver, copper, and zinc.
5k gold is a low-karat gold alloy, and low amount of pure gold content and high amount of other metals make this alloy unappealing to investors and jewelry connoisseurs but also problematic from metal allergies standpoint.
Is 5k Gold Magnetic?
No, 5k gold isn’t magnetic, it’s diamagnetic when yellow gold is alloyed with other non-magnetic or paramagnetic metals like silver, iridium, palladium, ruthenium, platinum and rhodium.
5k gold becomes magnetic when gold is mixed with ferro-magnetic metals like iron, nickel, cobalt and some forms of stainless steel.
5k gold contains a minimum of 20.85% pure gold and 79.15% other metals. When these other metals are magnetic or ferromagnetic, they make the whole 5k gold object magnetizable because the amount of diamagnetic yellow gold is too low.

Is 5k Gold Hypoallergenic?
No, 5k gold isn’t hypoallergenic, it’s allergenic.
5k gold commonly causes skin allergies because this gold alloy contains too little pure gold and too much other metals, some of which are triggers for people with sensitive skin.
Two obvious examples are copper (moderately allergenic) and nickel (highly allergenic), but even silver can cause dermatitis in sensitive individuals.
Bottom line is that 5k gold isn’t safe for people with known metal allergies.
Is There Bullion Made From 5k Gold?
No, there’s no bullion made from 5k gold. 5k gold has never been used to produce investment grade bullion because the amount of pure gold in this alloy is too low (only 20.85%).
Are you interested in investment-grade gold coins and bars?
24k gold is used to create gold-investment bullion and these are the gold IRA-approved coins and bars you can include in your gold IRA account.
For example, check out how many pure gold coins and bars Augusta Precious Metals offers (note: Augusta Precious Metals is the best gold IRA company in the United States. They waive all fees for 10 years for all new customers).

Is There Jewelry Made From 5k Gold?
Yes, there’s jewelry made from 5k, though it’s extremely rare compared to jewelry made from higher karat gold, especially 14k and 18k gold.
Here’s an example of 5k gold jewelry sold online. One of the rare piece I could find online.

What is the Hallmark for 5k Gold?
Hallmark for 5k gold doesn’t exist because 5k gold is a non-standard, low-purity alloy that isn’t required to be hallmarked. Traditional systems and gold purity regulations are designed to certify higher levels of gold purity, and 5k gold alloy has too little gold in it.
How Much is 5k Gold Worth?
5k gold is 20.85% pure, and is therefore worth 20.85% of the current gold spot price.
Gold spot price changes multiple times during the day because of the interplay of supply and demand so the value of your 5k gold changes with it.
What is 5k Gold? Is it Real? Conclusion
5k gold is a low-karat alloy containing only 20.85% pure gold, with the remaining 79.15% being other metals like silver, copper, and zinc. This minimal gold content makes it unappealing to investors and jewelry enthusiasts.
The alloy isn’t magnetic when mixed with non-magnetic metals, but becomes magnetic with ferromagnetic metals like iron or nickel. Due to its high percentage of other metals, 5k gold isn’t hypoallergenic and commonly causes skin allergies.
