Few pieces of jewelry are as classic as solitaire necklaces. As a single stone dangling from a gold chain, they are unassuming and can be worn with just about anything. In particular, a simple diamond necklace can easily move from the workday to date night, easily adapting to the outfit you wear with it. Choose an informal sweater dress for daytime, and the small diamond necklace will add sophistication. Just that little drop of light can finish an outfit with ease. Then, in the evening wear it with a little black dress to highlight your neckline. Here, it adds understated elegance to an otherwise basic date night outfit.

Of course, solitaires also serve as awesome couple necklaces. Surprise your girlfriend with one for Valentine's Day and she will wear it for a long time. Even before you propose, this diamond solitaire will serve as a symbol of your devotion to her. Diamonds really are a girl's best friend. Are you about to propose? Consider a simple diamond necklace that will coordinate with the engagement ring you give her later. Or, select from our couple necklaces that are designed with romance in mind.
