I would really appreciate any advice/help you may be able to provide in relation to buying an engagement ring in San Francisco in the coming weeks. We are there on hols from the 12th Feb and want to purchase an engagement ring - but not in the likes of Tiffanys etc. We have a budget of approx USD$7000 for a min 1.5ct, G-I, Vs1 - Si1 (RB or asscher..can''t decide!). Our budget includes the setting price. Essentially, we are looking for trustworthy, diamond wholesalers who are well established and will look after us!! Thanks in advance. (also.. feel free to let me know if my requirements and budget actually match up!).
