Goldstone is a man-made stone that's glass filled with crystallised copper. The brownish-orange colour is more common than blue goldstone.
With subtle ambient lighting goldstone sparkles incessantly.
The story that's widely shared about how the material came about is a myth. The real story suggests goldstone was created by an Italian physicist and astronomer from Murano in 1712.
The way it's produced today is not particularly straightforward. The fast majority now comes from China.
Goldstone is one of only three man-made stones that we feature as part of our collection.
