Guild Wars 2

I have a full set of Rabid armor that i would convert in Celestial armor.
Then i need 6 Celestial Intricate Gossamer Insigna where each one needs 5 Charged Quarts Crystal, every Charged Quarts Crystal needs 25 Quartz for a total of 25×5×6=750 Quartz.
I have in my Home Istance Quartz Crystal Formation that give me:

For a minium of 3 Quartz at day.
I did it 2 times and i have 6 quartz. So without think that i have 6 quartz.
750/3=250 Days?? Is possible??
What i mistake?
Tnx

You can buy the quartz (not charged) from TP as they are not account bound. Or you can collect them in a zone called Dry Top. Not sure if there are other ways to get them currently.
It takes you 30 days (1/day) to make enough charged quartz for a full set of celestial armor.

Charged Quartz will also drop rarely when mining the Quartz node and rarely from Trick-or-Treat bags.
