Etsy sellers design all different types of stackable rings, from simple rose gold stackable ring sets to sparkly birthstone stackable rings. You can shop for individual rings from Etsy sellers and mix and match a one-of-a-kind stack for your finger. Often, you can select the quantity of rings you’d like to create your stack. Including your birthstone in your stack is a fun way to personalize your set. Emerald stacking rings are a popular choice, too. These rings are easy to style because the green hues of this stone pair nicely with jewel tones, gold, and white gold bands. You can also personalize a stackable ring set by working with an Etsy seller to add a personal engraving or message.
