 Hi WHFSR...I don''t have an answer for you on your girdle reflection question but one of the best lighting conditions for a diamond (at least mine) is in a Church. I had read this on PS but forgot about it, then last week, found myself in Church waiting for someone and looked down at my ring which was totally on fire. At every angle. It is funny that just wjhen I begin to question my diamond''s performance (I''ve come to realize that I don''t neccearily have high expectaions as much as perhaps unrealistic ones), I look down at my ring and it''s all firey. |

Let me get this straight?
Are you the kind of person, who buys a car, puts it wheels-up-roof-down, and then steps on the gas to see how fast it is? Sorry for the sarcasm in this, but the approach seems similar to what you are talking about now, putting the stone table down, and then judging its light performance. In this position, you have light entering the stone through the pavilion and exiting again through the pavilion. This has no meaning after you set the stone into a jewel, because there will be no light entering through the pavilion anymore. Once again, sorry for the sarcastic tone, but I could not resist it. Live long, |

My ring also looks good in church, in stores with halogen lamps like Home Depot, etc. You see no fire in flourescent light, just whiteness. My ring looks least good in home lighting, so don''t sweat it. I sometimes think we overdo our descriptions of these stones and then people have unrealistic expectations about how they are really supposed to look! They do look great in certain lighting, but that lighting is not in all environments!

wheeeewww...you hit the boundry point there, I was ALMOST offended. and yes, I do test gas mileage with the car upside down as it gives a max mileage point to work off of--something to shoot for. But seriously, no it is not that I judge it upside down. It is because the diamond is wrapped in its little paper and everytime I unfold it the diamond is upside down. Then as soon as I see it their is this magnificent ring of fire with longer and shorter burst encircling the diamond. Everytime I see it I get real giddy and excited,then I turn it over and there are some pinpoint flahses a little burst then some period of inactivity with alot of sparkles which is generally the case indoors, though with less dispersed lighting there is of course a bit more fire, but nothing indoors that makes me GIDDY like it did when I first open up the diamond upside down. Also, the girdle reflection fire is VERY apparent when it is in my ring type stone holder (equivalent to being mounted). I have been using it while typing and watching tv on my computer and in 1 house light and the computer light the reflection located about halfway down the pavilion (you know where you can see the girdle reflected from the pavilion side?) is constantly firing and flaring, even when I don't see any activity from the table up (albeit it is hard to see both at the same time). Which I do not recall in my last diamond and I was wondering if this is the way it always is, as I had never thought to check the girdle reflection for fire before....but it is very present when say, sitting on a knee and I have a side view of the diamond. NOTE: while I welcome any suggestions as to how to get the best light performance from my diamond, I am well aware that angles and different lighting will affect light performance, though I do still need to do more research...in particular observations...before REALLY understanding how it affects that performance. All though I am nervous and somewhat excited to find out how it performs at my girlfriends house. All of their lights are open fluo coils. I haven't seen anything like that here.... |

LOL Paul - you''re funny! With rounds I would agree.... they''re performance runners. But with other diamond shapes sometimes there is a sculptural quality that encourages viewing from more than one view (top up). I don''t think IRBs are sculptural in 3D though. Not like a nice big chunky deep cushion can be hehehe ;) |

Let us look at your question logically.
You have purchased a stone with a good Idealscope-image, thus with very little light leakage. This means that light entering through the top (table plus crown) of the stone will mostly leave again through the top. Leakage would mean that light entering through the top leaves through the pavilion, or light entering through the pavilion leaves through the top. Since your stone has little leakage, if you put it upside down, light entering through the pavilion will most likely leave again through the pavilion. Basically, you could say that you can judge the same brilliance upside down. As for fire, with the higher angle of the pavilion, compared to the crown, and/or with the bigger surface of the pavilion, it is probably safe to assume that the rays of light exiting in this way through the pavilion will get more dispersed, and that fire is thus much more apparent when looking at the stone upside down. So, I think that it is safe to assume that a better-cut stone will also look better if you look at it upside-down. Live long, |

She does, although secretly she covets an ACA.  lolI''ve heard rounds called "boring" more than once on here, and all I can say is, I''ve had my stone 15 months, and I can go into new places and STILL get different visual effects. I wouldn''t call that boring.  There is beauty to be appreciated in all shapes, imo.  Personally, I''d love to own one of each.
