Most places don't have the specs to give you because most consumers aren't savvy enough to ask. Many will contend that such minute details aren't needed to make a decision. Others will give you a visual estimate of things like table and depth %.
If you want all the numbers you'll need a Sarin report (or the like). I don't know how many Sarin machines are out there, but not too many. I guess all you can do is ask and give the vendor the chance to get the info for you.
thanks for the info!anybody out there have experience w/ tiffany?do they provide this info?if not what visual numbers can i look for to get a decent ring(table,depth?)
Tiffany's diamond certificate provides the depth and table percentages, as well as the crown agle and pavilion depth percentage (among other info.)
They keep the certs in NYC, but I asked them to fax me a copy of the cert for the diamond I was interested in. They were somewhat surprised, but very professional and accomodating and said that it would be no problem. It was good for them - I plugged the specs into the HCA and got 1.5, which was nice considering I'd already fallen for the diamond.
Over the course of 4 or 5 weeks I had them ordering (and holding) several rings - all under a carat - so it's not as if they were only obliging me because I was some kind of millionaire. I found the staff and the whole buying experience just wonderful.
Hope that helps! Good luck with your search.
