120760702 Now, here’s where 21k gold comes in - a bit of a sweet spot that many people don’t talk about enough. With 87.5% gold, it sits right between 18k and 22k in terms of purity.

At Alamo Gold and Silver Refinery, Paul Evans also buys gold in any form. “The gold purity - the higher it is the more it’s worth,” he said. The spot price of gold is for 24 karat.

Jewelry stores and gold buyers are busier than ever as gold prices recently hit an all-time high — $3,400 an ounce — nearly double what it was just a couple of years ago.
