Starting a new thread from an earlier one discussing a potential stone I am looking at. My retailer (DS in Chicago) is telling me that this stone on their site is from a vendor that does not have the capability to produce images for me. They also threatened me with their 10% off the setting going away but its honiored if I move forward today - pisses me off because I''ve read that about them so many times...
Anyway...
They sent me angle ranges that they said guarantee perfect IdealScope images and H&A images as long as the stone is within these ranges:
PA 40.6-40.9
CA 34.0-34.9
T% 55-58
D% (a function of t/ca/g/pa but generally 60-62%)
ST 50-55
LH 76-80
*ANGLES*
BUT... If the PA is a tenth lower (40.5) it''s ok if the CA range is higher...34.5 to 35.5
AND... If the PA is a tenth higher (41.0) it''s ok if the CA range is lower...33.5-34.5
Basically for every shift in PA by 0.1 degree I''d adjust the CA range by 0.5 degree...and PA under 40.5 and over 41.0 is getting into dodgy areas.
*TABLE*
IF...table is 59-61 and PA is 41.0 or 41.2 the diamond could be nice if CA is 33.0-33.5 (but it is then a 60/60 make - a different look than the 55-57 table H&A we deal with - needing longer lower halves...very bright but not as fiery).
IF...table is in the low 50s the crown is going to be much higher. Need more details on these, but they can resemble transitional or antique cuts depending on the details."
Is is safe to assume this is correct? And here are my stone details that all fall within these ranges (although barely for some):
5.72*5.76*3.50
Depth% 61
Table% 58
CA 34
PA 40.6 or 40.8 (hard to read the cert)
Cutlet None
Oh yeah, cannot see the stone unless it''s purchased from the vendor!
Please let me know your thoughts on the issue of not being able to see the images and whether or not the claim that these ranges always produce near perfect images.
Anyway...
