hi Diana.
as a general rule, i have found jewelry in madrid to be quite a bit more expensive than in u.s.a. and with the VERY weak dollar, i do not think that europe would be the place to beat that price but ya never know.
for us not so knowledgable about jewelry, i think you need to explain and/or show us what a "hidalgo ring" is.
i did a quick search online and came up with this froogle results page --->
http://froogle.google.com/froogle?q=Hidalgo+Jewelry+Moon+and+Stars+Enameled+Ring&hl=en&lr=&sa=N&tab=ff&oi=froogler seem to be a few of them and all a bit different. the one that comes closest to your quoted $700 price is at
www.billbarnes.com/product.asp?engine=froogle&product=8646 for as low as $485.
all i can figure out is that "hidalgo" is the designer (?).
if you fax the info to me here in madrid next week (closed this week for semana santa) i can have a look around. see
www.spainsim.com/contact/callfax.htm for my office hours. you will have to fax during my hours as i receive them manually.
or can�t you e-mail it to me, that would be a lot easier.
saludos,
jer...
p.d. where in florida are you? my uncles and aunt are jewelers and they have a shop in hollywood. if you tell me the exact ring you are looking for, maybe i can get them to hook ya up
