Anniversary Stone: Diamond jewelry
It is unbelievable that one would have to wait ten years for a diamond. But such is tradition, and while you may have splurged on THE gem before this milestone date, 'tis is the time to hit it big. While it is impossible to ask that each anniversary be marked with a diamond carat -- although it is a nice thought, by now one would be able to claim a 10ct weight stone -- such an important date as the ten year mark should be celebrated in style. A one-carat is a must. Diamonds are especially nice because they can be worn easily both by men and women. Perhaps an up-graded pair of wedding bands with diamonds would do justice to your ongoing commitment to one another.

Traditional Theme: Tin
Remember the Tin Man who found that he indeed had a heart? Well, this is one explanation for this traditional theme. Another would be the meaning derived from the properties of tin -- a malleable metal often used in coating to help prevent corrosion. After all, 10 years together definitely shows strength, lack of corrosion and most surely malleability.

Modern Themes: Aluminum / Diamond
