Gold is traded in USD because the U.S. dollar is the world’s primary reserve currency, making it widely trusted and accessible. This practice began after World War II when the Bretton Woods Agreement linked the dollar to gold, setting a global standard. Even after the gold standard ended, the habit stuck due to the dollar's stability and its dominant role in international trade, keeping it the go-to currency for valuing commodities like gold.
Gold is traded as a commodity. It's value fluctuates on a daily basis. That said, an ounce of gold is currently traded for about $1700 USD. 10 karats is not the quality that is traded, so it will be worth less than that. I'd estimate it'd be worth about a thousand USD. But I wouldn't pay a dime for it as it has very little functional use because we humans like how shiny it is and wear it as a stupid status symbol.
