Reddit reviews Sterling Silver Simulated Emerald-Cut Cz Engagement Ring - Size 9

It's this ring. This one the company has is about $20 so it should give you a nice stopgap ring. I would recommend finding a gold ring sooner than 5 years down the road though. How much did you old ring cost? Because if you go with a moissanite or a colored stone, you could get something for less than $2k (I assume your ring was more than that because I've heard you can't insure something under $2k with ring insurance, just personal property insurance.)

Edit: I found four more rings for you, none with a halo though. Link 1 Link 2 Link 3 Link 4
