When choosing the karat level for your gold chain, here are a few things to consider. The karat scale goes up to 24, with 24k gold being 99.9% pure. The higher the karat, the more valuable the gold. But higher karats are also softer, so they’re easier to scratch and dent. Then again, low karat gold loses some of its color because it has higher levels of silver, copper, or other alloys. The reason 14k is the most popular karat for gold jewelry is that it is more affordable and durable than higher karats but still has brilliant coloration. Browse through the vast inventory found on eBay to see why a 14k gold chain is an excellent choice.
