Gemstone Drop Rates
I've herd a lot of talk about this but I haven't herd of an exact number. I've herd of 4% chance (1 in 25) and I've herd of 1 in 10 (10%). In my experiences currently im at about 1.4% chance since I have opened 80 chests and have only gotten 1... either I have really bad luck and riot should check on my account ratio or the gemstones are a lot rarer than everyone has lead to believe.
