Guys, for cheaper (but slightly lower quality) natural diamond, what is your recommended shop? I heard JP's diamond are mostly 4.5k+ for 0.5 carat, and they didn't really sell lower quality. I know there are reputable online shop like Bluenile and JamesAllen, which I can get 0.7 carat for around the same price (but ofc slightly lower quality), but wanted to know if there is similar reputable offline shop.
Slight background story, my gf is not really diamond-savy and she won't like it if she find out that I spent a lot for the ring. I don't want to give lab grown diamond, and 0.5 carat seems too small for me (I think sweet spot is around 0.7 carat). For other minor details (especially those cannot be seen in naked eye) I actually don't mind that much..
