The total number of jewelry Jessy had before going to the store is 10 necklaces+15 earrings= <<10+15=25>>25
At the store, Jessy bought 2/3*15 = <<2/3*15=10>>10 earrings.
When she got back from the store, Jessy received 1/5*10 = <<1/5*10=2>>2 more earrings than the ones she bought at the store from her mother.
The total number of earrings Jessy received from her mother is 2+10 = <<2+10=12>>12 earrings.
The total number of earrings Jesy has after being given 12 more from her mother is 10+12 = <<10+12=22>>22 earrings outside the jewelry box.
When Jessy puts all the jewelry in the box, the total number becomes 22 new earrings+ 10 new necklaces + 25(the total number of jewelry she had before) = <<22+10+25=57>>57
