On August 16, the Australian company Leonard Joel will hold an Important Jewels auction, the main headliner of which will be a ring with a dazzling diamond of 21.13 carats.
Sydney-based Leonard Joel holds three auctions each year. At this upcoming event, a Modified K Color SI2 Brilliant Cut Square Diamond Bevelled Ring will be one of the many intriguing pieces to be featured. The ring is expected to be worth up to A$900,000.
There will also be an 11-carat round modified diamond ring with I color and VVS2 clarity. This ring is valued at A$700,000.
Another notable item is a 5.29-carat cushion-shaped Burmese pigeon-blood ruby ring set with 10 brilliant-cut diamonds totaling 2.5 carats. This ring has an upper estimate of A$900,000.
The auction is expected to generate A$8.6 million in sales, organizers said.
Leonard Joel will showcase the work in Melbourne and Sydney ahead of the auction.
Last year, the company auctioned a 20-carat H-colour, VVS2-clarity emerald-cut diamond ring for A$1.6 million, the most expensive diamond sold at auction in Australian history.
