This is a scam.
This site copies photos of products on Etsy and other sites. I ordered a hexagon cut alexandrite ring, and later found the original seller, Ohjewel, on Etsy. The ring from Olivenorma is a plastic toy. Seriously, it's not even trying to look genuine. I've taken a photo of both rings side-by-side on my review of the product in Etsy ("Hexagon cut Alexandrite ring for women vintage unique cluster Alexandrite engagement ring white gold silver art deco moissanite wedding ring" by Ohjewel). I wish I could upload a photo here so you know never to fall for these Chinese/Hong Kong scams, claiming everything's free only pay delivery. These sites change names regularly (I've seen many copies on Facebook since), but they use the same tactics to trap us. Please be careful!
