Here is some allegedly "classy" Yurman jewelry:

$5,100...for, um, what? Something you can buy at Wal-Mart?

These are classy - if you are 80 and having your portrait painted for the family estate...

Y-necklaces? The cast from the third season of friends would approve!

Looks like a gaudy piece of cocktail jewelry to me...

Look honey, my bracelet matches the travertine counters!

And another cocktail ring, just for good measure!
And since you edited, things I think are standard classy old-money jewelry - pearl studs. Simple diamond studs. Small, tasteful hoops. I've never liked the big gaudy crap that rappers wear because the jewelry overshadows them - people should wear jewelry, jewelry shouldn't wear people. I have no problem with expensive jewelry if it's worth the price, but I think Yurman is paying for a name and nothing else.
