SoapRocks are handcrafted bars. They resemble quartz and other stones such as, Opals, Amethyst, Turquoise, and Citrine, Tigers Eye, Jade, Emerald, Marble and many other precious gems. SoapRocks are very mild and extra long lasting. As they gently cleanse, soap will slowly weather away like a stream stone in geologic time, exposing the beauty locked away within. Since nature cleanses best the manufacturer of SoapRocks uses unique blends of whole herb extracts, vitamins and minerals, from aquatic and botanical sources. All ingredients come together in the biodegradable bases of SoapRocks.  Truly unique birthday gift. Instead of getting someone an actual birthstone, get them their birthstone in a SoapRock.
