The matte “matte” mother ring is designed with minimal decoration and a calm, matte finish. We aimed for a neutral look that can be chosen without regard to gender.
Each small birthstone is carefully set one by one using a technique called “engraved setting,” in which the stone is secured by surrounding it with the metal. Another feature is that the stones protrude less, helping reduce snagging on clothing and the like. Birthstones can be selected from 1 stone to 3 stones. This is the type with one birthstone.
Simple in form, yet full of family memories.
This ring is for families, accompanying the memories of the day your child was born and the time you will share together from here on.
We also offer a baby ring in the same design, so parents and children or the whole family can wear matching pieces.
