Every anniversary you and your partner share is cause for celebration, but some anniversaries feel more like a milestone that others. Many couples choose to celebrate the major milestones like their 10th or 20th anniversary or a big life event like having a child together with a piece of jewelry that reflects their love for one another. If you have a big anniversary coming up, here’s what you should know about diamond anniversary rings.

Traditionally, the 60th wedding anniversary is considered the “Diamond Anniversary”. A more modern take on anniversary milestones gives you the opportunity to gift diamonds on your 10th anniversary. One popular diamond anniversary ring style is a diamond band that will pair nicely with an engagement ring and wedding band. Together, the three rings symbolize how your relationship has evolved.

Picking out a diamond anniversary ring—just like picking out any piece of jewelry—is a highly personal experience. The 4 Cs (cut, color, clarity, carat) still apply to picking out a diamond but the typical style of anniversary rings means you’ll have more flexibility. Here are a few options to consider when you’re shopping for a diamond anniversary ring.

An anniversary gift should be anything but generic. If you want to make a diamond anniversary ring extra special, consider personalizing it with an engraving of your initials, the date of your wedding (or another significant date) or a meaningful quote. Not only will the engraving show that you put a little extra thought into the gift, but it will also ensure the piece is truly one of a kind, making your anniversary that much more memorable.
