The diamond ring (lot 80) carries a catalogue estimate of $200,000-$300,000 and is only coming back on to the market because the vendors have now had “their fun” with it and would like to see it go to a new home.
Another important international item is the Colombian emerald and diamond suite (lot 180) comprising a necklace, earrings and ring and a catalogue estimate of $300,000-$400,000.
The 420mm long necklace features 13 clusters set with graduated cut emeralds totalling 51.14 carats surrounded by round, pear and marquise cut diamonds weighing in total 47.33 carats.
The emeralds in the drop earrings weigh 6.13 carats and the diamonds another 4.77 carats while the ring has a 6.94-carat emerald surrounded by 3.56 carats of diamonds.
A diamond Rolex Oyster Perpetual Day-Date platinum wristwatch (lot 246) also should fascinated buyers while the auction’s antique pieces include a selection of Australian jewellery.
Of particular note are two rare Federation brooches (lots 110 and 115) – an Australia-shaped seed pearl and diamond configuration by Duggin, Shappere & Co. and a gem-set work of art by Wendt dating from about 1900.
