Which pieces of jewelry do you think are worth worrying about the quality of diamond and which aren't? Which are the bottom quality/color/cut you would consider for:
stud earrings
solitaire necklaces
solitaire rings
and how about for pave anything...
My stud earrings are H VS2 hearts and arrows but that is definitely overkill. I've seen J SI2 earrings that looked extremely good, but they WERE ideal cut.
So they had the sparkle--and no one gets close enough to your ears to see the color in a well-cut J (which can be seen from the side, not the top) or the minor sort of inclusions visible in SI2.
Ditto for solitaire necklace.
Solitaire ring--gets tricky here. If going with round, ideal cut you can get away with a certain amount--but not as much as in earrings and necklace. If going with other shapes, the cut will hide less and you need better quality. You can definitely see a lot more--but different people see different things. To me, I like a white diamond, even from the side, for a ring(Ilike my rings in high settings that show the side). I have an F color and don't think I'd want to go below G, for an e-ring. And I'd really prefer E or F (the idea of a D is nice, but it costs too much money).so far as inclusions, I like not only eye-clean, but don't want to see big black spots with a loupe, either. I have an SI1. What I want is easily possible in a GIa or AGS graded SI1--SI 2 I've heard it's possible but I think it gets harder. And I've never seen one. If I had a fancy shape, I don't think I could go this low. A lotofthe fancies just show EVERYTHING and you need to go up toVS (and with something like an emerald cut, VVS). I would stay with ideal or very good cut.
I don't like pave in general very much.
I have to say, all the above is theoretical--if I see a diamond in person and I like it and it looks good to me (including through my 10X loupe) I would take it and be happyand not care what the paper specs said it was.
But in general my criteria would be-- high color/eyeclean/looks sparkly--though there does have to be a balance. I don't think I'd prefer an F with no sparkleto a J with a lot of sparkle. But in real life,you don't usually have to make that choice.
