A couple from China had a rather stressful proposal after a wave momentarily buried the ring into the sand.

Eason had planned to propose to his now fiancé Rachel on a beach in Cancun, Mexico, on July 17.

But the romantic proposal almost turned into a disaster when Rachel fumbled with the ring and dropped it in the sand.

Video shows the moment Rachel let go of the ring, which immediately disappeared in the sand and under a foamy wave.

Luckily, Eason quickly spotted the ring seconds before another wave approached and managed to capture it within a handful of sand.
