I have only recently got ours,

DD has a Raw dark honey necklace and bracelet (we use it as an anklet) and I have a matching necklace. TBH I have not noticed MUCH of a difference but maybe it takes a while to work?? I do know my AF pain has been a lot less severe when I have mine on and I always wear my Amber pendant when I have had m/c to help ease the pain.

It won't do any harm, BUT there are cheap inferior products out there so make sure that your buying from a reputable seller.

Got ours from Ebay but they come with an Authentication number and the supplier will fix the necklace if it gets broken.

HTH Nae x
