can a jeweler re-size a platinum mounting head?

[ElleElle]

Hello,
I am upgrading from a 1.81 to a 2.52 round and already own a platinum setting I like a lot. Is it possible and cost effective to have the jeweler just re-build the head to accommodate the new stone size?

Depends on the setting. Post pics from top and profile.
Also what is the metal.

Hi Gypsy-
I don't currently have the mounting in my possession as I'm trying to consign it but have a feeling it will probably not be sold. I do have a photo from the top of it (which might not be very useful).
I can tell you thought that it's a replica of the T&CO "Lucida" mounting in Platinum: http://www.tiffany.com/Engagement/Item.aspx?mcat=148203&groupSKU=GRP10003&origin=engagement&search_params=param+0/0/0/0/2#p+1-n+1000-c+-s+-r+-t+-ni+1-x+-pu+-f+false+2-lr+-hr+-ri+-mi+-pp+
