What type of gold necklace are you shopping for? A traditional, classic addition to any man or woman's jewelry box is a simple gold chain. Cable, herringbone and snake chains are fine strands of gold intertwined, and they can be worn alone or with a pendant. Most gold necklaces come in a variety of lengths ranging from chokers (about eight inches in length) which rest just beneath the throat, to 18 inches, which sit against the chest. For a man's gold necklace, 18 inches should be appropriate. However, the necklace length is a personal preference. Research the recipient's jewelry box to determine whether a choker or a full-length chain is in order.

Other more elaborate chains are available in varying degrees of width and length. A Byzantine-style necklace will feature a weave of multiple gold strands. These are often 5/16 of an inch and come with a lobster claw clasp. Rope necklaces and triple-strand gold necklaces are a bit more detailed and eye-catching.

For a subtle spin on this traditional favorite, go for a white gold necklace. As popular among men as it is among women, white gold is bit less obvious while being incredibly versatile. Whether you choose yellow or white gold--or even the trendy rose and green gold options--most aficionados agree that a 14K gold necklace is one of the best jewelry investments you can make.

If you've already purchased a gold necklace, or are looking for something to accompany your gift, pendants offer a way to personalize the jewelry. Diamond pendants are very popular gifts for women, but pendants are available in all shapes and sizes and can also reflect religion (in the form of a cross or the Star of David), hobbies (such as a soccer ball or figure skate), or interests (such as animals, hearts or musical notes), as well as enduring love.
