Where is the ring ?

After her old ring lost since last week. I have replaced a new one as same as before ring.
How to prevent it to lose in this is change finger from little finger aka “niw-koi” to ring finger aka “niw-nang” and place on her left hand!
P.S. old ring had lifetime for half of day (12 hours) and two rings worth 750 B.
