Jewel of the Kimberley 

Breathtaking Lake Argyle, the ‘Jewel of the Kimberley’, is situated in the far north of Western Australia. Thousands of visitors travel each year to witness the spectacular manmade wetland constructed in the 1970s. Nestled among the rugged Kimberley landscape and located near the Argyle diamond mine, the lake holds a staggering 32 million cubic metres of water, more than 20 times the size of Sydney Harbour..

Southern cross design

The reverse design of each ingot portrays the lake with seven rare Argyle pink diamonds in the night sky. The spectacular diamonds represent the five prominent stars of the Southern Cross together with the pointers – Alpha Centauri and Beta Centauri.  Each ingot’s obverse showcases an eighth Argyle pink diamond which has been handset into a representation of a starburst.
