This ring is simply gorgeous and all of the learning materials that Tungston Rings & Co gives you help you learn everything you need to know about tungston. I asked other tungston stores about hardness and MOHs scale and I got nothing. I saved so much money and not to mention, my fiancé loves this ring. The free shipping is great also to help ease your mind about costs. He and I agree this is simply the best.
