1 Hour of Mining:
With a Diamond Pick:

Spoiler

Average you can earn is 6960 Gralats.
Diamond Picks cost 400 Gralats each, every 1200 hits.
With calculation, 1 Diamond pick can last for approx 44-45 emeralds.
The average I calculated you could mine in an hour approx is 240. Which means you will need 5-6 Picks every hour. This is 2000-2400 gralats.
So essentially the average you can earn mining emeralds now is 4560-4960 Gralats per hour, and thats if you mine non-stop, including time for when you move to mine another rock.
(An Approximation).

And using those calculations, the average xp you can earn for emerald in an hour is 24000.

The most I calculated you could mine in an hour approx is 180. Which means you will need 6 Picks every hour. This is 1500 gralats.
So essentially the average you can earn mining rubies now is 2820 Gralats per hour, and thats if you mine non-stop, including time for when you move to mine another rock.
