Anniversary Gemstones - Life's milestone markers. For those who enjoy traditions, giving an anniversary gemstone to a loved one makes a fine gift idea. Much like the colored gems that represent each of the 12 months of birthdays, there is a gemstone believed to represent every year of married life. Milestone anniversaries – such as the first, tenth, twentieth, twenty-fifth and century mark – are considered to be celebratory events and in many countries are thought to be good luck if given and worn during the corresponding year of celebration. |
