The Building Blocks Of Style

Humans may have an average of 23 pairs of chromosomes, but you only need one pair of Chromosome Earrings to express your love for all things genetic! Sold individually so you can pay homage to your favorite gender, these delicate sterling silver X's and Y's are a blast to mix and match. Unfortunately, they don't replicate via mitosis, but they are handmade from sterling silver by self-proclaimed nerd, Tiffany Ard, and are the perfect building blocks for your geeky jewelry collection! Handmade from sterling silver in the USA.

By junior high, Tiffany Ard was a self-identified nerd. "I was too afraid of being hit by a ball to do sports, too shy to be a theater kid, too unpopular to be one of the popular kids," says the illustrator and science enthusiast. "The kids I spent time with liked writing stories and inventing languages and pretending to be time travelers." When she had a child of her own, Tiffany realized there were plenty of toys designed to make tots smart and successful—but dorky for the sheer fun of it? Not so much. Her Nerdy Baby line fills the (cosmic) void. "The best gifts invite open-ended play and make kids feel empowered to experiment fearlessly," she notes. "If they happen to learn some fun science facts, all the better."
