I've searched and been unlucky. Looking for a 3.5-4.5 carat m-z FL-SI1 pear shaped diamond with a large Culet. Any ideas where to look? is there a name for this cut I'm unaware of?
It's close but not exactly what you are looking for. I came across this antique pear on ebay recently and it made me drool! It's 2.92 I and VS2 according to the seller.
Halo it! You'd need to call someone like Old World Diamonds and see if they can find one. You probably can't search yourself other than auction sites. Finding a well cut pear that large will be a challenge, and in a color that low, even harder.
