Promise ring is a cheap ring used between the proposal in front of the family to the engagement party. Most girls ask for a bracelet instead. “Söz bileziģi”

When engaged you wear matching, thick, gold rings on your right hand.

After you are married you change the ring to left hand. So, I can safely say that only one ring is enaugh.

A diamond ring is optional but most women gets a tria ring (three diamonds) after first birth, a fiver(beş taş) after the second and a fully embedded diamond ring “tam tur” at 5th anniversary.
