Identifying A Ruby With Lasers, Magnets, and X-rays

The eBay ruby

Kings, queens, and rich people everywhere agree: rubies look great. Their clarity and red color make them wonderful, shiny jewelry pieces, and I find them beautiful. But if you’re buying one, there are many similar red, clear gemstones which are much cheaper for the seller to pawn off as ruby. How can we know that we aren’t getting ripped off when we buy a “ruby” online?
