5 stone diamond and sapphire band, real or repo?

[MakingTheGrade]

I'm supposed to be on ban island, but I've wanted a ring to wear on my pointer finger, something more like a band and less like a solitaire that would be sturdy enough to withstand me being clumsy (Ive already scratched up softer gems, even spinels!). I came across this 5 stone, but don't know much about "Antiques" including whether this is actually likely to be a real antique or a reproduction?

It's 18k yellow gold and 1.4tcw and the old cuts and wonkiness and tiny rose cuts in between the prongs makes me think Victorian maybe?
Also would love any price comps, it's listed at 1.3k, and I have no idea what aspects go into pricing antique/vintage pieces. I've bought and returned from this vendor before a few times and have found them overall accurate in their listing photos though they're a mass wholesaler so limited info in terms of diamond color/clarity/weights etc though they do guarantee natural and not synthetic (no mention of heat treatments though).
