Genuine Jade 3 String Necklace

During my trip to San Francisco 2 years ago, I visited its famous China Town and bought this jade necklace. Jade has been believed by Chinese people that it brings prosperity and wellness. Recently it is scientifically proven that jade stones, with their emission of far-infrared rays, stimulate blood circulation and revitalize skin cells. So, the wider the contact area, the more health benefits. I've been forgetting my purchase and it's been in my suitcase until yesterday. It's never worn.
