Recently, on Atlantic, I noticed on a vendor 3 commodity tickets for 1,000 perfect emeralds each (all 3 gone within 24 hours btw...). Now, since the price was particularly convenient, I doubt they were bought gems then put together in one ticket. When price is convenient usually, it means they were mined. So, since they were all on the same vendor, I would imagine that it might have been the same miner finding them. Since I also mine from time to time, I know what, at least for me, the drop rate is for perfect emeralds. And I thought, WOW, how many miner-hours equal 3,000 perfect emeralds ? Anyone knows ?
