Is there beauty under the ground? Well, in Coober Pedy, Australia, there is.
The town is full opals, and some of them are worth millions of dollars.
An opal’s color is generally the most important factor in its value. There are not a lot of opals that have color – 95% of them are colorless.
To look for the best gems, men dig long holes in the ground.
Some of them build houses in those holes to live with their families.
‘Dugouts’, as they are called, have no windows – but their temperature is easier to regulate. Coober Pedy is a desert, and during a day temperatures can vary from 1 to 30 degrees Celsius!
This post is a bricolage of the book’ Opal Town’, by National Geographic Learning.
