Materials (especially the bright Swiss blue color of the stone) and workmanship are great, but you may want to order one size up (a size 6 is usually slightly big on my right hand and very big on my left, but I had to use soap to get it off my left hand). I really like it, so I will not return it.
I bought this ring several years ago, but just noticed it again online. Size 6 was true to size. The design is so unique that it immediately caught my eye. It is sort of mystical.
