Royal mails Recorded service no longer cover precious metal and gems in jewellery up to the value of £50 The recorded service will cover only to £20, I’ve still managed to get some items through pretending their value is lower, but this could prove expensive should an item go missing.
They do however try to push you into using their next day special (costly but worth it if the items is £70 plus)
but who want to pay for that.
I’ve been looking at other services but wondered which you use and have found reliable and not expensive
