Is there a way to reset the default mouse cursor?

I'm making a custom clickdetector script, and I'm changing the mouse icon to the ROBLOX one for clickdetectors whenever a certain part is under the mouse. However, I want the mouse to function normally after the mouse's target is no longer the brick. How can achieve this? My current code:

mouse.Move:connect(function()
    if player.Character.Humanoid.Health ~= 0 then
        if mouse.Target then
            local target = mouse.Target
            if target:IsDescendantOf(parts) then
                print(target)
                if mouse.Icon ~= "http://www.roblox.com/asset/?id=433782737" then
                    mouse.Icon = "http://www.roblox.com/asset/?id=433782737"
                end
            elseif not target:IsDescendantOf(parts) then
                --mouse.Icon
            end 
        end
    end
end)

Thanks in advance.
