Mariel Nader’s one-of-a-kind Birthstone Mineral Soaps were inspired by the shades and shapes of the 12 birthstones. Made with only high-quality, pure ingredients and enriched with invigorating minerals, vegetable-based dyes, and soothing vitamin E oil, these lustrous soaps are handcrafted in small batches without the use of molds. The artist hand-cuts and carves realistic angles and facets into the vibrant soap rocks once they’re set in their gemstone-like shapes, giving each one the unique look and feel of an authentic birthstone. Handmade in Connecticut. $20. Buy here.
