Unidentified

All I am sure of is that this is a very pretty orb weaver. Your spider has an impressive pair of pointed shoulders …..so I am going to guess it is in the genus araneus…..it could be A angulatus or A circle….2 different species that can look very similar. But your spider is more colourful than any pictures of either I could find….so it could be something else entirely
