So over the weekend, I purchased yet another 5-stone, but this one is an old cut. I am having second thoughts and am still within the return date.
So my question is: do you think this ring looks significantly different to justify owning a 3rd?
I think it look an awful lot like the one on your pinky finger (though definitely larger). Unless it was a steal (or your budget is unlimited), I'd return it and save your $$ for a piece that will diversify your collection.
Sometimes a piece of jewelry just speaks to you and if it's similar to other pieces you have, it's just because you have a specific taste! Can you imagine if you have two paintings that emphasize the color purple and you fell in love with a third that heavily features that same color--would you specifically return it because who needs that much purple?
At the end of the day, how you feel about a piece of jewelry is something only you can decide. Ask yourself, if you do return it, will you end up buying something similar again down the line?
Good luck with your decision!
Another vote for it looking very much like a slightly larger version of the pinky ring.
I'm also in agreement with Yenny's suggestion - hold out for another ring that looks a big different - if you are looking for variety in your settings!
