Stings MH - adding new items??

I'm playing on a mod, i tried to add new gems in the vcb file and tried copying the format but didnt work. im new to all this kind of stuff, so forgive my noob-ness
there are new gems in this mod, but still useless and i want to hide them like the others.
i tried doing this:

in the .vcb file
======================
Chipped Sardonyx: 9001
Flawed Sardonyx: 9002
Sardonyx: 9003
Flawless Sardonyx: 9004
Chipped Onyx: 9005
Flawed Onyx: 9006
Onyx: 9007
Flawless Onyx: 9008
Chipped Quartz: 9009
Flawed Quartz: 9010
Quartz: 9011
Flawless Quartz: 9012
Chipped Zircon: 9013
Flawed Zircon: 9014
Zircon: 9015
Flawless Zircon: 9016


in the config file i have this
(9001-9016 are the new gems i was trying to add to the gem filter, 2050-2079 and 2090-2094 are the vanilla gems, which are correctly working and hidden)
===================================================
item colours[2050-2079,2090-2094,9001-9016]: -1,-2

 

I checked the guide, it helped me customize the MH to make a filter to remove the trash clutter which was a huge benefit already. mainly what i am asking is for advice how to edit it myself to customize it for the mod.. to further learn about the editing process i guess? im just trying to figure out how to write the commands in properly.. i guess i am on my own with this one :/
i dont understand how it works. im not asking for support on the mods. just seems like a simple solution to add more items into the vcb file. but idk. barely learned to make a filter today with stings
