I have misplaced an earing from a necklace and earing set my friend bought for me. Put them in the zip bit of my purse when flying home. Not very safe i now realise. The thing is they came from past times which has now shut. I have put a wanted request on ebay as there are no matching ones listed and i have also checked p[ast times online. Any other ideas were i would get a replacement would be gratefully received. They are rennie macintosh birth stone jewellery.

I am not having much look with earings this week, i was in Lanzarote and one of my other earings blew out in the wind, a cheap pair luckily
