Liners
In most cases, you can choose a ring with or without a liner.
If you choose a ring without a liner, you will be able to see the mokume gane effect on the inside of the ring as well as the outside.
A liner covers the inside of the ring, and in the case of engagement rings, the setting. You would thus see the mokume gane on the outside of the ring only.
Width
Our wedding bands and some of our engagement rings can be created to a customized width ranging from 3-10mm. In some cases, a client can specify a width greater than 10mm.
Size
Due to the nature of mokume gane, we will send you a ring gauge to confirm the exact size. After size is confirmed, the ring gauge will need to be returned to us.
We want to ensure that the ring will be a perfect fit. That’s why we suggest these three options:
Option 1: You check your size at your closest jeweler.
Option 2: We send you a ring gauge that is returned to us once you have determined your size.
Option 3: You send us a ring that perfectly fits the finger on which you want to wear our ring. We will return it along with your purchase.
