Fred rings copycat

As you might have seen, Fred, the jewellery brand, has launched a serie of rings based on kate moss's tattoos. I found the collection very cute and the rings look nice worn all together. I love thin designs and these particular rings have small diamonds engraved that look very cute. One day as I was in Galleries Lafayette in Paris, I passed by the Fred booth and thought it would be an occasion to try them rings. The sales lady told me the costed 510 euros. I remember telling myself that I would rather spend those euros in a pair of louboutin than in such a tiny diamonds. That beeing said; I received an email from groupon yesterday, promoting tiny diamond rings for 29 euros. I was like WHAT?? I clicked and then saw that the 29 euros diamond ring is a copy cat of the Fred ring but from another jeweller. Well I can't resist when I see that big of a bargain, so I went on and ordered two for 49 euros. I dunno what to expect and will show some pics when i receive them. For now, looking at the snapshots form both websites, I don't see the difference. ( copycat below from Mazal Diamonds)
