I did quite a bit of looking today - all the online sites listed here seem to run around $1000 to $1100 for about 3/4 tcw studs. Sam's club, about the same, here's a link.

Edit - Pelican seems to be munging the url, trying to add an emoji to the url. Sam's club item 756423.
I couldn't find a similar offering at Costco's website, and like I said, there's no store close to me.
I did check eBay, I'm wondering what's the catch with nyexquisitejewelry? 20,000 positive feedbacks, about 1/2 the price of the ones above. Like these, for instance -
.75ct 3/4ct ROUND-CUT G/VS2 GENUINE DIAMONDS IN 14K SOLID GOLD STUDS EARRINGS
or
.75ct 3/4ct ROUND-CUT G/SI2 GENUINE DIAMONDS IN 14K SOLID GOLD STUDS EARRINGS | eBay
Or these? $53?
