I think old diamonds (settings and stones) win hats down, eveytime. From what I understand old stones and cuts are sought after again for that very reason. IMVHO new stones and settings are too white and bright: too cold.
--Previous Message-- : It might also be due to the fact that most : 'old' jewel settings have yellow or red gold : in the back and silver or white gold in the : front - this gives diamonds a 'warm' glow. : : Most new jewels are set in platinum or white : gold that is rhodinated. This gives the : diamonds a vary 'white/cold/colourless' look : that most people like these days. :
