There's so many associated factors SCN- for example, on many of the teenie table older stones I've seen the table is not exactly in the center- add this to general "wonkiness" of the crown, pavilion, and culet and results are going to be "unpredictable"
Hey D! I agree so many other factors, especially with an older cut stone!!!
I am currently on the hunt for an older stone that will coordinate colorwise, with a heart shaped stone I have. I plan on using them together in a pendant---in remembrance of our dog we just lost.
I found a stone, but it has a really really tiny table and a very high crown-so I am worried it will be a dud of a performer!
