Ebay has several very reputable sellers of vintage and antique 14K gold rings for women and men that have quite a distinct collection to browse through.
In past eras, some men kept a piece of their wealth in their jewelry that they wore daily, or jewelry was a symbol of status. In my opinion, many of the vintage estate jewelry collections have some of the most unique and beautiful men's ring styles.
Buying a 14K gold men's ring is an investment because men's rings are much larger than women's rings. So finding the right ring for your man is both an investment financially, and emotionally. When you love someone enough to spend enough on them to buy 14K gold, then you want to make sure that you get the perfect gift.
