'Fire of Australia', a 998-gram opal worth almost ₹4.6 crore and considered as the world's finest uncut specimen, has gone on public display at the South Australian Museum for the first time since its discovery 70 years ago. Known for its colourful texture due to internal light diffractions, 90% of world's 'precious opal' is produced in South Australia.
