Memorial Tattoo/Jewellery

Hey! I just wondered if anyone here has a memorial tattoo or piece of jewellery for the child they lost? I'm thinking of getting either a tattoo or maybe a necklace to remember the baby I miscarried and I'd like some inspiration. If it was to be jewellery, would you guys consider the birth stone to be the month you miscarried or the month the baby was due? Thanks in advance for any replies! ❤
