I'm looking for diamond studs and have read from you experts that cut is the most important factor. So, I've been looking at 1ct E-G color ideal cut diamonds in various clarity grades. Prices are from $4k - $6k each on Blue Nile. My jeweler this afternoon quoted me $7k each and to be set in platinum, I'm looking at $15k-$16k for the pair of earrings. Is it better to buy the loose diamonds from Blue Nile (and not pay any sales tax!) and have my jeweler set them? Or should I pay a bit more with my jeweler whom I trust? I've never bought diamonds online and I'm a bit nervous about it. Would appreciate any advice you can offer. Thank you!
