Gemstones of all shapes and sizes will be on display in Tauranga this weekend.

The National Gem and Mineral Show, held at Tauranga Racecourse on Friday, April 30-Sunday, May 2 has something for everyone.

Gorgeous and intriguing rocks will help keep the kids entertained for hours, and there are plenty of activities planned.

The show is split into two halls – one where collectors and those intrigued can buy anything gem and mineral related, and the other with plenty to keep the young and young-at-heart entertained, including an ice block with hidden gems, machinery area for cutting and polishing rocks, rock naming competitions, identification competitions, scavenger hunts and much more.

Kids can participate in activities such as making your own gem ‘magic wand', cracking open your own gems and more.

'There will be crystals for Africa,” says Tauranga Gem and Mineral Club member Graeme Dewhurst. 'It's great for the whole family and people tend to stay for hours.”

The Tauranga Gem and Mineral club conducts a field trip on the last Sunday of every month for gem hunters, club nights on the second Monday of every month at the clubrooms, located at the Historic Village, with separate meetings for junior and senior members, Tuesday work nights for cutting and polishing, and regular collection viewing nights between members.
