The chances of an individual gem being an uncut onyx is 1/100,000,000, as confirmed by Jagex Moderators on their weekly Q&A session. Since each bag gives 40 gems, the chance of getting one uncut onyx from a bag is 1/2,500,000.
The probabilities in this section are an estimation based on the data of opening 410 bags full of gems, totalling 16,400 uncut gems being obtained.
According to these estimates, a bag could be expected to bear around 74,255.1 value of gems on average.
