My Sever is Aquarius

SDG, SRG and STG.

Well on my server there abou the same price :x

in my server SRG sells the highest then SDG>SPG>etc>etc

well on my server its 3 dbs for: SDG,SPG,SRG,STG, the rest are cheaper

economically, sdg, srg are even.

but in terms of acquisition, its harder to acquire a super tortoise gem. in the item mall, the super tort goes for approx 3.5 dbs.

SDG-->SRG-->SPG

Depends on server, in my server SDG, SPG and SRG is same. 3 dbs.

Wow 3 dbs for those gems.. On my server its only 2 ;O

Could you guy say your sever please
