not sure why its worth your while
jewish jewelry stores are 50% reduction from these prices
Tough to compare prices alone.
I bought an engagement ring from a Jewish jewelry store. It fell apart after a few years and they didn't stand behind it.
Bought a replacement from Kwiat with Vente-Privee referral credits a while ago and it's still perfect, plus they promised to stand behind it.
That being said, their prices are high. And I doubt anyone is paying for these offers.
