It's said that diamonds are a girl's best friend, and thanks to Hammon Diamond Jeweller, one lucky lady has the chance to win a magnificent $15,000 diamond ring at the Ladies Long Charity Lunch next month.

Women are encouraged to secure their seat at the Ladies Long Charity Lunch at ASB Baypark on July 3 to win the 1.2 carat diamond solitaire ring in 18 carat yellow and white gold on a diamond set band.

All funds raised from the event will go towards Good Neighbour Charitable Trust and Te Aranui Youth Trust.

Te Aranui Youth Trust operations manager Wendy Nicholls says there's also the opportunity for women to spoil themselves with incredible auction items on the day.

'You may like to take a few of your friends on the trip of a lifetime to Phuket,” says Wendy, 'or indulge in wine on the rolling hills of Tuscany.

'Perhaps you'd prefer to stay local and support your child's hockey team with a professional coaching session with Black Stick Gemma Flynn?

'Bid on a private hunting trip in a jet boat up the Ureweras for yourself or your partner, or bid on a vasectomy from Bay Urology. There's something for everybody.”

Wendy says the Ladies Long Charity Lunch is no ordinary charity event.

She adds: 'It's designed by women for women as a luxurious guilt-free day of self-indulgence with fine wine, food, specialty markets by Little Big Markets and incredible speakers.”
