I'm posting the info I got from GOG on an emerald cut stone. Please take a look and tell me what you guys think. I have no one else to talk to about this! The independent jeweler doesn't bring me such detailed information on stones, just the certs. and the stones to look at. Is it really best for us consumers to see the "Megascope" infor and diamond x-ray? I like having as much information as possible, of course. I'm a little confused about the diamond x-ray "red" picture, that indicates "light" properties. Can someone explain that a little more? does red w/ black mean the stone will sparkle, etc? And the info on the megascope about the light (this stone is rated in the "ideal" range, I think)...is this truly meaningful information? I'm so grateful for any feedback; thanks in advance! jeannie Jeannie |

other than the huge table its pretty nice. But I don't like the glassy EC's so I wouldn't buy it. They can get others in pretty easily. ........... Karl has joined the diamond trade and is now posting as Karl_K |

hi, when i mentioned the table size he and another guy who works there said that despite the numbers the diamond is beautiful and that numbers don't always tell the true story. is this possible or should i stick to the numbers alone? jeannie Jeannie |

also, can you tell it's "glassy" just by looking at its picture...or do you just go by the numbers? this is a tortuous process! jeannie Jeannie |

Date: 7/5/2007 9:09:38 PM an EC can be glassy and very beautiful for someone who likes that type.Author: shminbabe also, can you tell it's 'glassy' just by looking at its picture...or do you just go by the numbers? this is a tortuous process! jeannie a 73 table and a 9% crown height does not a fiery EC make. That doesn't mean its not pretty its just not what I would look for in a EC. ........... Karl has joined the diamond trade and is now posting as Karl_K |

A glassy EC isn't what I want either. After all, I'm sacrificing the "bigger look" so I'd want the stone to be beautifully faceted and fiery. Question, though. Help me understand this: can you see that it's a glassy stone from the pictures or are you ascertaining its glassiness from the table size? Also, what about the red x-ray pic? Doesn't that indicate a stone's potential for being fiery? I'm so confused!!! Argh! I really appreciate all insights. I'm sure this topic has been done to death on the forum. jeannie Jeannie |

The red scope pics predict light return not how its returned. low crown height and a large table is what I'm basing the glassy conclusion on. There was a weird one that GOG had a while back with a 70% table and a 14% crown height that Jon said was pretty fiery but they aren't that common usually a large table == low crown height and combine the 2 == glassy. Which is the case here. ........... Karl has joined the diamond trade and is now posting as Karl_K |

Okay, that helps to know. when they sent the pics to me they (Tim) said something like, "this is why I don't necessarily pay attention to numbers....take a look at this one!" b/c I said I wanted one with a smaller table size. So how do I predict how light is returned, then? the "megascope" rates this stone in the "ideal" range for brilliance, fire, scintillation (or similar categories) - - does that mean anything? I'm sorry to be so clueless. I really appreciate the diaglogue! jeannie Jeannie |

If they do they haven't told me and it hasn't been peer reviewed. Have him run the helium stl file thru the AGS software he has and see how ags rates it. Im predicting a 5 on a 0 to 10 scale. ........... Karl has joined the diamond trade and is now posting as Karl_K |

AGS...(American Gem. Soc.?) so is that the one to seek if I wish to ascertain a stone's fire, brilliance, scintillation? What exactly is a Sarin Report and how do I interpret it. As long as we're talking...okay, if stone A's diagram shows four "steps" from the center and stone B's diagram shows three "steps" - - is this a significant difference in quality, fire, brill., scint., etc? Do ECs vary in number of "steps"?? THANK YOU, strmrdr (what does your name mean?!) jeannie Jeannie |

Another question: is there a site that actually lists things like ranges for tables, depth, crown heights, good girdles, etc, for fancy shapes that would indicate the "prettier" (i.e. fire, brill., scintill.) stones? so I know what to seek as I do my late-night stone searching...?! I only want to talk to jewelers about stones that are worth it. then they'll say, you can't always pay attention to the numbers, you have to see it. I know it's true, but just how true? In your opinion? jeannie Jeannie |

Yes EC's vary in the number of steps on the top and bottom, it is really complicated because you could have 2 diamonds with 3top/4bottom and 3t/3b that look exactly the same face up. 3t/3b is the standard.... kinda outdated but my about me is posted here: http://www.pricescope.com/idealbb/view.asp?topicID=10083 ...........

Date: 7/5/2007 11:54:55 PM These are a bit outdated and I don't agree with all of it but it will get ya started.Author: shminbabe Another question: is there a site that actually lists things like ranges for tables, depth, crown heights, good girdles, etc, for fancy shapes that would indicate the 'prettier' (i.e. fire, brill., scintill.) stones? so I know what to seek as I do my late-night stone searching...?!

In your opinion? jeannie http://www.gemappraisers.com/oldcutgraderules.asp The numbers get you in the ballpark then other info has too hit the ball. That includes having a vendor act as a filter for you. If a vendor wants me to go against the numbers they have to prove too me why that is so. For example the large tabled EC I mentioned above, I would have dismissed it but because it had the high crown Jon felt it had a lot of fire and I agreed with him that it was very possible it did. ...........

okay, storm rider, that's great. so ya love tornados? how do you feel about hurricanes? yikes, they scare me. this is great tutorial info you're giving me. i'm reading it all and will use it to cull out the stones i'm not interested in. if i could get excited about a shape other than an EC, i think i'd have a bit more leeway but doesn't an EC need to really be "right" in so many domains to really look its best? in the case of the GOG diamond, clearly they think it's a beauty, and i would too b/c i wouldn't pick up on the nuances you've pointed out. whiteflash has many ECs on their list that I can review as a preliminary. So you recommend AGS software as a means of measuring light leakage, light return, etc? I want depth within certain range, tables, too, and then crown height, to ensure a fiery, sparkly, brilliant stone. or, one that has those qualities along with well-defined steps. Re: Asscher cuts...do they appear larger ("face up larger"?) than an EC will or is it basically the same - and, which cut do YOU prefer, Asscher or EC? I know it's a highly subjective question. what did you buy for your fiance and are you still happy w/ it? do you work the diamond biz now? well, thanks for the good info so far. much appreciated.  jeannie Jeannie |

Date: 7/6/2007 1:50:17 AM I'm not Storm, but asschers tend to face up smaller that EC's. And Storm prefers asschers, knows them inside and out. He's not in the business. Just a dedicated consumer, who loves helping people like yourself. Jeannie, keep working with GOG. They will find you a great stone. I have bought two stones from them. The asscher and an oval. Best of luck!!

Chiming in late, Jeannie! I'd pass on the GOG diamond. Remember the AGA cut chart from your previous post? Well, this diamond failed on 2 things. 1. Low crown height at 9.7%. I'd like it at 12% and higher for FIRE 2. Large table at 72%. I like to keep it at 65% and under. Both contribute to the diamond looking glassy and having no/less large flashes of coloured light. Always keep the AGA cut chart in mind when shopping for your EC. If you want a stone that faces up a decent size (for step cuts), stick with an EC. Asschers tend to be smaller than ECs. Not always but more often smaller.

Chrono, and all: THANKS! At least I have something to go by, now, when I search...your specifics help me a lot. I really appreciate it. Hopefully I'll have another stone to show you soon. In fact, I had one but y'all shuddered at the x-thin to med. girdle, so...oh well. It was out of my price range anyway. But it was soooooo beautiful in person! sigh. jeannie Jeannie |
