I’ve used Blue Nile several times and had no issues at all. Looks like they have a bunch of Sapphires

DeBebians is hands down the best jeweler for both custom work and stock pieces. They have really good pricing. I was connected with them by a friend who has used them for years and have been blown away by my experience with them, the quality of my piece, and the work they’ve done for others that I’ve seen. The way they brought my very specific vision to life is incredible.

You can go to their website and find great stuff, but I’ve honestly had such amazing luck with them just filling out their quote form on their site. You tell them what you want, your budget, etc and they get right back to you. They were started by two best friends I believe over twenty years ago. The guy is the design pro and the woman completely owns stone sourcing (mined or lab, you can get anything from them for stones).

They’re such a “best kept secret” of the gemstone and jewelry internet. Everyone who works with them adores them, they’re just good people. Impeccable quality. Their jewelers are really good and have been with them forever. Debebians.com and their “Get a quote” link is easy to find. Talk to them, haha when you do you’ll understand my hype. Professional and sweethearts!

I’ve seen Brilliant Earth around for a while if you want lab grown, but I’ve never bought from them personally.

I’d also recommend a Philadelphia jeweler that ships pretty quickly and has always had good products that I have bought from several times, Steven Singer.
