Who is going to buy this, I am wandering...? Looks like a physical version of this diamond app that you hold a virtual diamond or something (worth nothing) but it's rare, so it costed like 10k to get it. Besides, there are at least 3 other metals or man-made materials that come to my mind, several times harder and more durable than gold & nickel. Just wandering aloud.
