I''m looking to purchase a tiffany-replica channel set engagement ring. The true Tiffany setting (from Tiffany) comes with 10 round side stones (VS/F) totaling 0.89 carats. The vendor''s tiffany-replica comes with 10 round side stones (VS/G) totaling 0.35 carats. Since I''m going with a 2 carat center stone and I''d like it to be more in line with the channel-set ring I saw at Tiffany, I asked how much it would be to have larger side stones. They said they could create the ring using 10 round side stones (VS/G) totaling 0.80 ct for an additional $1,000. That seems like a steep premium. The platinum setting with 0.35 ct is $2550; with 0.80 ct, I''m looking at $3,550. Is it reasonable?
