Hello everyone. I am looking to purchase my g/f an engagement ring in the near future. I am seriously considering buying a 1.65 E/VS2 Round Brilliant from Tiffany's for $34,000. I also looked at the following: 1.38=$22,000, 1.77=$40,000. My g/f wears a size 5. It seems like you get what you pay for. I have looked at many other places (BlueNile) etc and it seems that most places accept flaws in their diamonds that Tiffany's does not. The rings I looked at Tiffany's sparkled like there was no tomorrow, even when i took them out of the lights. Ladies, am I crazy for spending this kind of money for a 1.65 carat at Tiffany's or is the quality/warranty etc really worth it? Your honest opinions would be greatly appreciated.
