Dig around your mom’s jewelry box lately? Odds are she still has a few of these funky cocktail rings from her wilder days. There are also troves of these jewels at vintage boutiques and estate sales. Or you can always take a perfectly respectable shortcut and order this jeweled starburst cocktail ring ($75, jcrew.com). Czech-glass rhinestones and hand-painted resin cabochons (polished gemstones) arrange in a starfish pattern to light up your lovely hands. Mami would be so proud.
