If the gem marks, then it's not a ruby.3 Scratch the gem with a series of other items. Use a piece of glass and a steel knife. The knife has a hardness level of 7 and should not be able to scratch the ruby. Scratch the red stone with rough sandpaper. If there is no noticeable effect, then the gem is likely to be a genuine ruby.4 Rub the ruby against a clean white porcelain tile. If it's real, the ruby will leave no color or streak behind.
