We know the comforting scent of vanilla, the soothing smell of jasmine, and the floral notes of rose and lilac. But for those who have ever wondered what these popular fragrances look like, there are these necklaces by Carrie Parker. Inspired by her parents—a chemist and a science teacher—Carrie geeks out on the molecular geometry of four favorite scents with her birch plywood necklaces. Each one is shaped like the essential compound that's infused into the wood for a multi-sensory experience. The hexagonal geometry of benzyl acetate represents the sweet essence of jasmine, while the zig-zag shape of geraniol characterizes the compound that your nose calls "rose." They make distinctive gifts for science teachers, stylish nerds, and molecule-loving moms. To refresh the scent, just dab the pendant with a drop of fragrance oil (not included). Handmade in Pittsburgh, Pennsylvania.
