An anniversary ring, a diamond solitaire, or even pearl earrings all qualify as fashion jewelry. They are beautiful, as jewelry should be, but they are not meant for everyday wear. Colored stone jewelry, such as sapphire, ruby, and emerald accessories are almost all considered fashion jewelry. You can find engagement rings with these stones in them, but they are always relegated to a supporting role, never the centerpiece of the ring. That place is reserved for diamonds.
There are also less traditional styles of jewelry that fall into this category. Toe rings are a relatively recent accessory, but they are exactly the type of accessory that is referred to by fashion jewelry. You are not going to wear toe rings and then put on a pair of boots, they are meant for sandals or possibly heels. Brooches may seem a little old fashioned, but they are also outfit dependent jewelry.
Fashion jewelry can be worn by men as easily as women; although the items will be quite different. Where a woman might wear a tennis bracelet; a man can wear cuff links. High end shirts and jackets will have holes for custom cuff links, rather than buttons sewn into them. Some will even sport both. Instead of wearing a diamond pendant; a man wears a tie clip or stud. Jewelers always carry a selection of precious metal tie accessories.
The last piece is one that can be worn by either a man or a woman; and it is the watch. There is a difference between a watch worn simply to tell the wearer the time; and a jewelry quality watch. The difference lies in the style and composition of the watch. A plastic banded Casio watch may give you the time, but a diamond studded Rolex will turn heads while telling time. So whether you are looking for watches, rings, necklaces or cufflinks, fashion jewelry is fundamental to accessorizing.
