I got one from Amazon that I have been wearing over a year now with zero issues. It's a knife edge, so it has a little something extra, and is super comfortable. Zero issues with tarnishing, hasn't been prone to scratching. Here it is paired with my e-ring.
Here is the Amazon link. It's about $15 with free shipping, Prime if you have it. One thing of note, is it only comes in whole sizes. I am a half size and just went to the next size up and it worked out just fine.
It's truly a beautiful ring on it's own merit, and for the price, it's incredible.
