Prince George to be given opal-laden toy

Baby Prince George is set to carry on the royal tradition of acquiring gems, when he's presented with a toy truck full of South Australian opals.

Majestic Opals, based in the mining town of Coober Pedy, is offering the truck and three other opals set in koala, boomerang and kangaroo charms.

Tourism Minister Leon Bignell says the gifts will be handed to SA government representatives to pass on to the Duke and Duchess of Cambridge when they visit Elizabeth, in Adelaide's north, on April 23.

"Coober Pedy is recognised as the international opal capital, mining 86 per cent of the world's opals," he said in a statement.

"Perhaps, when the young prince is older, and inspired by his opal-laden toy, he may someday visit Coober Pedy.

"I am thrilled that Their Royal Highnesses will be taking such a distinct and beautiful part of South Australia home with them."
