Not just the stones used, but the band style can also make the ring look unique. Instead of using a plain band, you can choose alternatives like a twisted band, flat tapered band, split shanks, paved bands, channel bands, knife edge bands, etc. Make sure to choose metal colors that match with the center stone.
Yet another popular trend for simple diamond rings for women is providing delicate details on the band. Choose a setting featuring etchings like simple antique floral detailing, filigree details, milgrain details, etc. Another good option is to add engravings like your name, or a quote in the band.
What can be more minimal yet so beautiful if not a solitaire ring? It is not necessary that you need to choose a large solitaire diamond for an amazing look. Instead, go for a small solitaire centerpiece with the appropriate setting. You can choose any colorless diamond shape and pair it with a plain band.
