Curious, where are you buying real rubies from at that quantity. A quick google search returned about 10 different places, but they look more like the jewelry quality level.
I bought the ones that are round cut so yeah they are the jewelry quality ones you probably saw. I might end up turning a few into a set of earnings or a necklace or something. It was tempting to get a rod of raw ruby and smash it or something, but it is also just cool to show off a pile of rubies cut and ready to put into jewelry that I am just using as tokens in a mining board game. :D
