It is hard to describe, but it is extremely white, contrasted with a darkness of the steps. It almost seems to glow in this low light. Anyone else experience this?

I can see the steps so clearly then, and like you said...it seems to glow. ........................ You say you want diamonds in a ring of gold...but all I want is you...

NewEnglandLady Ideal Rock Total Posts: 3,157 Last Post: 11/24/2009 Member Since: 7/27/2007	I love that type of lighting as well--my favorite is in dimly lit restaurants. I feel lke those bold flashes of light are more pronounced. I catch myself staring at my hand and wondering how it can be so bright in such a dark room. I also love a cloudy day, it seems to show the pattern more than sunlight. ETA: I got my ultrasonic cleaner last night and right now the sun is shining through my office window--it's like a fire parade over here! Maybe i just needed a really clean ring to appreciate sunlight!

But there is really something special about low light and my asschers. I wonder if there is any scientific reason for this? LitigatorChick "A cause may be inconvenient, but it’s magnificent.

I wonder if there is any scientific reason for this? yes, large virtual facets, lots of contrast, and step cutting. When they were designed soft lighting was the norm for indoor lighting. ...........

In other words the real facets interact in such a way too break up the light into zones creating the effect of more facets. In an asscher under the table these virtual facets are very very large and under the crown facets a mix of med. and small. The difference in appearance between an oec and a RB can also be explained by virtual facet size with the oec having larger virtual facets. Larger facets both real and virtual gather and return more light in soft lighting. This can be thought of as bigger mirrors catch more light in soft lighting. (not a perfect comparison but close) A larger quantity of smaller(but not too small) mirrors(small virtual facets) are brighter in more direct lighting. ...........

Rothbard, in The Anatomy of the State John Swinton [1829-1901] Chief Editorial Writer of the New York Times (Considered "the Dean of his Profession" by his peers), when asked to toast an 'Independent Press' in a gathering at the National Press Club, circa 1880 "There is no such thing in America as an independent press unless it is in the country towns. You know it, and I know it. There is not one of you who dare express an honest opinion. If you express it you know beforehand that it would never appear in print. I am paid... for keeping my honest opinions out of the paper I am connected with. Others of you are paid similar salaries for doing similar things.... The business of the New York journalist is to distort the truth, to lie outright, to pervert, to vilify, to fawn at the feet of Mammon, and sell his country and race for his daily bread, or for what is about the same thing, his salary. You know this, and I know it and what foolery to be toasting an 'independent press.' We are tools, and the vassals of rich men behind the scenes. We are jumping-jacks. They pull the strings and we dance. Our time, our talents, our lives, our possibilities, all are the property of other men. We are intellectual prostitutes."

strmrdr Ideal Rock Total Posts: 23,296 Last Post: 10/9/2009 Member Since: 11/1/2003	I feel in my gut that the key too scintillation in a diamond is not the movement of facets but the creation and destruction of virtual facets as the diamond is moved. I cant prove it yet but that is my theory. It would also fit that in soft light large virtual facets being created and destroyed would bring more life too the stone over small virtual facets. ...........

Effect of h&a yep can explain it, painting yep that too, patterns in asschers, crushed ice vs chunky, ring of death, pinfire vs broadfire it is all in the virtual facets. ...........
