You're better off using itemlinks and a function to get the position, links are more accurate.

local function GetBagPosition(itemLink)
    for bag = 0, NUM_BAG_SLOTS do
        for slot = 1, GetContainerNumSlots(bag) do
            if(GetContainerItemLink(bag, slot) == itemLink) then
                return bag, slot
            end
        end
    end
end
 
-- Get bag position of the Hearthstone
local _, itemLink = GetItemInfo(6948)
local bag, slot = GetBagPosition(itemLink)
