There are many curved engagement rings on the market. The center one here is one that our store makes. The question is that so little thought is given to the band that will fit later on. In this case, we made two bands to fit. One has some accent diamonds while the other is white gold only. The nice thing about these bands is that at a later date more diamonds can be easily added on either side of each band and on either band. Makes for an easy anniversary gift idea!
