Ok...

So the quck basics of my stone is an GIA - H - VS1 Princess its really an awesome stone an performs and looks phenominal

well when i was in the jelery store today of course everything under their cabinet looks awesome they have some colorless stones in there starting at F all the way up to D If you pull those out of the cabinet they still look colorless under the abient light. However My Fiances H looked a little yellow and so did the G. But of course you put them under the cabinet and they all look the same...Why is that

I noticed this effect under all the majors, helzberg, zales, whitehall, etc however in some independant stores it doesnt do this...Hounoush is one of them (they admitted their lights suck, as funny as that is) and baily banks and biddle (I know they are a major retailer)

Anyway I know the stone is awesome I have because of spec and how it performs and looks. She has gotten many many complements on her ring and how white it looks. I had a chart as well that said G and H are considered White and F-D ranged from hi white to Extremely white. (Obviously I know that G-I is near colorless and so on.) I just thought it was odd that they looked so yellow. Most people cant tell a difference. Do they do this on purpose or what..

Jewelry store lighting schemes usually include direct spotlighting as a priority. Diamonds seen in these lights perform at their very best because the sheer volume of light returned to the eye overpowers any fine tuning of the cut. These environments serve to mask inclusions because overall brightness, dispersion, scint and contrast are maximized. Similarly, the volume of light returned can mask body color so that a near-colorless diamond appears more colorless under bright lights.

You may have heard that a well-cut diamond can face-up more colorless than its lab grade. This is the same phenomenon (away from that lighting): A premium cut optimizes light return on its own to mask some of its body color: From the side it will look like its lab grade, but face-up a premium cut may appear more colorless in any lighting environment.

Diamonds all perform to some degree. It's the nature of the substance. The most important environmental consideration is lighting. Someone trying to sell cars will likely make sure they are cleaned, inside and out, and showcased properly. Someone trying to sell diamonds will place them in the best environment suited to maximize performance qualities and reduce negatives. Either way, you should kick the tires and take a test-drive away from the showroom before you buy.
