A Mt Roskill woman has taken to community website Neighbourly in a desperate bid to find her daughter's signet ring, which was tied to a "Happy Birthday" helium balloon's string and floated away.
Sarah de Pont said her daughter Jackie, 16, and her friends thought it "would be fun" to tie the gold signet ring to the helium balloon at her party last night, and see it floating around inside.
The four girls then forgot about it and went out for dinner. When they returned they went outside to have a spa, but left the door open.
"The next thing I hear are the girls screaming, but I didn't go down and see what's wrong because they are 16, they can't be drowning," said Mrs de Pont.
But her daughter was in tears because her beloved signet ring had flown away.
