The Echunga collection is inspired by the fabulous local mystery of the rare Echunga diamonds. Discovered at Echunga in the picturesque Adelaide Hills during the gold rush of the late 1800's, the true source of the original diamonds remains unknown to this day. Gerard appraised the original diamonds 1994 for the South Australian Museum, which sparked the idea for this unique collection. The origin of the Echunga diamonds remains a mystery, as there are no known Kimberlite pipes (which are responsible for the formation of mined diamonds) in the area where they were found.
Every coloured diamond in the Echunga collection is unique. Working with these exquisite natural gems has lead to the creation of a suite of one-of-a-kind jewellery. Key to each design is matching sets of different natural coloured diamonds to create beautifully unique jewellery. We use flavours as a helpful way to describe the colours of these very special diamonds.
Colour in diamonds is usually caused by the presence of an additional mineral within the chemical structure of the gem. Yellow diamonds have nitrogen present which alters the colour of the diamonds. Perhaps one of the greatest mysteries of all is how pink diamonds have come to be. There is great debate about the cause of colour in these natural gems, but the prevailing thought is that the great pressure these gems are under during periods of volcanic activity causes plastic defamation of the diamond’s crystal lattice.
