Go for Solitaire Beauty
Skinny bands are known to highlight the central solitaire diamond better than any other designs. Less metal often means the center of attraction is at the main stone. Any stone shape like round cut, oval cut, heart cut, etc., would go well with this.
Choose a Less Carat Weight
Even though 0.75 carats is the average carat size for most engagement diamond rings, these stones might look too big on the skinny bands. Therefore, you can opt for a 0.5-carat stone that provides a minimalistic style yet with a good grace.
Find the Right Settings
In a skinny band diamond ring, the center stone is the most important part, and hence, it needs to be secured using appropriate settings. For this, you can either choose a four prong settings or go for a six prong settings.
