When it comes to gift-giving, we know the struggle all too well -- how do you find the perfect item your mother, sister, or friend will wear year-round, that also shows how well you know them? Instead of taking a gamble, try out Blue Nile's Leave Nothing to Chance app, which searches the e-tailer's jewelry category to pull the best results to flatter every personality. Simply answer a series of witty lifestyle-based questions about the recipient (or yourself, no judgement!), and the tool uses those results combined with Facebook data to find a variety of sparklers they're sure to love. We thought the results were pretty accurate when we tried it out for ourselves, and we especially loved the wide range of items at every price point. You'll have the option to share your results on Facebook, Twitter, or Pinterest to serve as a subtle hint, and even better, you'll be entered to win a three-carat diamond tennis bracelet if you try out the tool before December 23. Head over to now to see the app in action. MORE:• Bring the Salon Home With the Byoutik AppThe Best Fragrances For Every PersonalityFind Your Perfect Nude Heel With Louboutin's App
