Spina Bifida is one of the most common, permanently disabling birth defects in America. It occurs when the neural tube, which forms the spinal cord and vertebral column, does not close completely during the first several weeks after conception. Each year about 1,500 pregnancies are affected by Spina Bifida in the US. Most children with spina bifida can and do live long productive lives, thanks to advanced medical techniques and support systems. For each bracelet sold, Essential Jewels will donate 10% of the purchase price to the Spina Bifida Resource Network. They provide services and programs to children, adults and families living with spina bifida. Bracelet is made with 8mm AAA grade natural yellow jade and white jade stones.
