I am a lover of all things jewelry, and have learned a lot about it over the years. One thing I learned from a jeweler is that 10k yellow gold is the best gold for rings. 10k yellow gold is the strongest of all the golds, so the rings won't bend or lose their shape so easily. I love to wear rings, and I have some 10k yellow gold ones that look as lovely now as they did years ago. Some of my rings are made with a less dense gold, like 14k gold or 18k, and they do lose their shape more quickly than 10k yellow gold. I love my 10k yellow gold rings that have a gemstone in them, it really shines when it's set in the gold and shows off the color of the gem. I like to wear the 10k yellow gold rings when I dress up, I feel so fancy when I wear them. My husband has been known to buy me 10k yellow gold rings by Black Hills Gold, with the signature leaves of different colors. He is from South Dakota so he's partial to the Black Hills Gold line. 10k yellow gold works great for rings.
