Prop 65

Products sold by are intended for experienced jewelry-makers, designers, and artists; while children under the age of 14 should use them with adult supervision.


We at Dakota Stones make it a priority to comply with federal and state laws concerning the safety of products sold to consumers through the retail website. Certain states have guidelines and laws to protect their residents of the possibilities of exposure to problematic nickel, lead and other chemicals.


As we refer to California's Proposition 65 or the Safe Drinking Water and Toxic Enforcement Act of 1986, we shall 'provide warnings to Californians about significant exposures to chemicals that cause cancer, birth defects or other reproductive harm.' For a list of possible chemicals, it can be found at As this list is updated yearly, we will continue to update products to ensure these laws are met.
