from my server after the patch normal gems can drop from monster most gem price drop in my server normal violet/moon cost about 300k-400k buy huge amount of them then go do the blue mouse quest each gem u buy 300k-400k but if u catch blue mouse u might get 5mets or 6 or 8 or 10 each met is 150k so u can easy earn alot of money by this way even if theres no cotobo but most blue mouse spawn at the left bottom corner of the maps
