Im looking to spend roughly 20k on a ring. I believe my girlfriend wants an asscher or emerald cut. What kind of diamond can I expect to afford? Is something bw 1.4 and 2 carats possible? Also, are there any recommendations on how to go about this process. There is a local jeweler in my town, who my family has supported over the years and seems very reputable. What do people say about this versus something like Blue Nile, or getting a diamond from blue nile and then bringing it to a jeweler? I live in new york city, so there is the diamond district too, but i would feel totally lost waking into a random store in the diamond district and also like i would be taken advtantage of. Thanks for any and all help everyone.
