This Tourette Syndrome necklace was designed with my own children in mind. I have two children with Tourette Syndrome, so celebrating Tourette Syndrome means everything to our family. I have been making jewelry for years and one day realized I wasn't making jewelry for a cause that means the world to me. This necklace is made with our thick 13mm gold filled discs on our popular gold filled satellite chain, to celebrate you or someone you love with Tourette Syndrome. The most popular length for adults is 18 inches. Tourette Syndrome is not as rare as most people think. Tourette Syndrome and other Tic Disorders are not rare. The current estimates are that 1 out of every 50 children between the ages of 5-17 in the United States has Tourette Syndrome or another Tic Disorder. We donate a percentage of our profits to the Tourette Association of America to help increase awareness of TS and donate to research for Tourette Syndrome. *** All jewelry will come packaged as gifts.
