A lot of diamond vendors sell labs in addition to naturals - Whiteflash, Blue Nile, Jame Allen, Brian Gavin.
If you are really interested, and have time and patience, choosing your own pair by yourself is pretty cost effective.
If you want ease + guaranteed quality, I’d recommend reaching out to Whiteflash or Brian Gavin. They can help you pick from their pre-paired inventory and set them for you. It’ll be a bit more expensive but it will be convenient and you can trust that you’ll get gorgeous studs.
If you want to go deeper, there’s another online forum that focuses a lot more on diamonds. You’ll find a ton of info there.
