[miss_c]

Hi,
i''m interested in this specific round shape ring:
carat:0.83
color: M
clarity: S1
cut: Ideal cut
price:$1300
Factor Grade
Light Return - Very Good
Fire - Good
Scintillation - Good
Spread or diameter for weight - Very Good

is it a good buy? i dont know much on diamond. but i like to get somethin good value, that is not too much of a bad quality either.

thx xxx

Can you give more details (certificate, crown and pavilion angle, table%, etc...)?

Why do you mention "Ideal cut" and the factor grades... Do these come from a Brilliance Scope? Some other instrument? The selller's oppinion?
