Hi Stebbo,
Do you know any reason( except Historical reasons ) Why for oval we should use min. diameter and for Round cut we should use average diameter?

Stebbo what would you think of a diamond that was faceted out of 3 point rough?

With my knowledge of rough, I''d say that would be a very shallow diamond, in fact a depth of 0%, quite a lot of leakage.![]()
I realize that a min-max average can be misleading, and I agree that the defined 4-point Helium-type average is more representative, but DiamCalc likes to represent the AGS and GIA''s girdle definitions, minor facet definitions, etc, it just seems weird it doesn''t represent their depth % definition. Rather it''s made generic with the other shapes which have their own uniqueness.
It will very misleading for DC clients too( DC is 10 old software )
We can do it only if anybody will give clear definition BOUNDARY between round cut and OVAL cut( How could we use average for round cut and minimum for oval cut, if we do not know where boundary is)
Firstly FUN, then Comfort , then Profit
DiamCalc doesn''t need to know where the boundary is, the user sets whether it''s a round or an oval by selecting either round or oval from the standard shapes available.Date: 9/13/2007 10:46:41 AM
