In a sense, yes, you can build your own ring. Stackable rings are basically sets of rings that are individually very thin, and can be stacked on top of one another (or kept separate on several fingers - it's up to you). Each stackable ring has its own style, so in this way, you can buy several different rings and stack them together to create your own design. You can even spice up your existing ring(s) by combining Stackables with them!
To give you an idea, here's a really neat tool which allows you to experiment with different designs from our website: interactive Stackable rings tool
(Just click and drag the rings from the left to the space on the right.)
The great thing about Stackables is that you leave your options open. Sometimes you want to wear just one thin, low-key ring. Other times, you want to match an outfit with various colors and prominent accessories. You can also sandwich your regular ring behind or between Stackables, allowing you to switch it to smaller fingers and still hold the ring in place. Stackables allow you to mix and match to suit your mood.
When you buy more than one you qualify for our 7% discount for ring sets. Check them out: Stackable Titanium Rings.
