Well I found a stone that I thought looked interesting based on the Depth and Table numbers and boy am I glad I ran it through the HCA. It scored 4.2=Only if price is the only object..... So, I admit I'm a little lost with all of the numbers, I'm sure that the score has something to do with the crown and pavillion measurements, but what EXACTLY threw this stone into the "ugly" zone? Info: 3.0 DSI1 Depth=61.8 Table=56 Crown height=15% Pavillion Depth=44% Anyone? Thanks! |

Abbey, Your crown is a bit heavy. Ugly seems like a pretty harsh word. Have you seen the stone? Neil Beaty, GG ISA Independent Appraisals in Denver There's never a crowd when you go that extra mile. |

Nope-haven't seen it, only looking for potentials online. It's an EGL which I hadn't considered before, just the price (~20K) was so good. So I'm feeling like if it sounds to good to be true...it probably is.

For a D, SI1, that's either the deal of the century or something is up--EGL or not. That price would be more appropriate for an J, SI1-2...I know b/c I just purchased a 3.01 EGL H, SI2, Ideal cut (verified by appraiser) and have a frame of reference for EGL stones. ??? _____________________________________________ Don't breed or buy when homeless pets continue to die. |

The pavilion seems deep - without the angles for crown and pavilion it's difficult to say, but you may have a deep-steep cut and therefore it might be an unattractive stone. Which EGL lab is it? The price seems way low, so use caution...but you never know. |

Ideal-scope based on those #'s. But if the roundin meant that the 15% was really 14.8 and the pavilion was really 43.8% and the gridle was sligtly thick, then it could be an OK stone. On the other hand it might be 15.2% and 44.2% with a very thin girdle. Labs should not waste peoples time with rounded % data.  Garry Holloway FGAA DipDT |

I'm not very experienced with reading the ideal scope... but what I see is lots of white especially around the edges. This makes the stone look smaller - right? Anyway I left off the girdle information which says it has a Medium girdle. Probably doesn't change much. Thanks for your help.

The pale ring of death in the table is more the problem. The outer white is OK.
