10K GOLD IS HAVING A MOMENT. IT'S BEEN DUBBED AFFORDABLE LUXURY.
LET'S UNPACK THAT...
10k gold is technically the lowest karat of gold that's still considered "fine" so marketing it as fine jewelry is fair. However, if you don't know that karat gold is, then it's hard to be an informed shopper.
A karat is a unit of fineness for gold. The most you can have is 24 karats, i.e. 99.999% gold. 10 parts gold and 14 parts other is 10k gold.
MORAL OF THE STORY?
10 karat gold has more other metal than gold.
I choose to sell a minimum of 14k because I want gold to be the majority in my designs. Buying 10k, 14k, or 18k is a personal preference and there's nothing wrong with any of those options; unless you have a nickel allergy, then be careful with 10k.
Cheers to being an informed shopper!
