This is a very special gift for my wife that I must buy this week! I am down to a final choice between two merchants both in my budget of $3000. From Norman Landesberg on W 47th in NYC, the GIA cert loose stones are .71 and .73 respectively, both SI2 and I color (I don''t see where it says cut on GIA cert. - round brilliant?) including I think a white gold setting. The Non-GIA cert are certified by the gemologist who owns the second store ((Haniken, also on 47th) and are 1.48 total, G color, ideal cut, round in 4 prong white gold. Haniken states retail value $5850. So which do I go with? Either way they are $3000. Which do I go with? VERY MUCH APPRECIATE YOUR INPUT!
