If you've ever bought a birthday gift for a kid, you know there are strict criteria—only certain colors, animals, and shapes are deemed acceptable by the pint-sized connoisseur. But when the present meets all the prerequisites, like this customizable necklace from Alex Hillson , it's received with sheer delight. Begin by choosing the recipient's age (from 3 to 9) for a number pendant, then pick out their birthday month for a birthstone-colored jewel, a star in their favorite color, and, last but not least, a charm: • A heart for love and kindness. • A lightning bolt to symbolize bravery. • A clover for a little good luck. • A unicorn for a bit of magic. • A seahorse to symbolize friendship. • A ballerina to represent grace and beauty. With all of their favorite things around their neck, the young candle-blower will surely give you the highest approval rating: "You're the coolest!" Handmade in Los Angeles, California.
