A fancy-intense blue diamond was the top seller at the Sotheby’s New York Important Jewels auction, fetching US$1.4 million ($AU2.08 million) on 13 September.
The ring featured a 2.42-carat cut-cornered rectangular mixed-cut VS1-clarity diamond and was sold within its pre-sale estimate.
An unmounted, pear-shaped, 10.21-carat, D-flawless diamond was sold within its pre-sale estimate and returned $US819,000 ($AU1.2 million).
Meanwhile, an 8.58-carat oval-shaped, D-colour, internally flawless diamond went for $US554,400 ($AU821,800) slightly above the pre-sale estimate.
Another notable piece was a 5.34-carat light blue marquise-shaped VVS1-clarity diamond ring, which sold for $US554,400 ($AU821,800), more than double the estimated return.
A 9.19-carat emerald Bulgari ring surrounded by diamonds also exceeded expectations, selling for $US428,400 ($AU635,028) while a 4.52-carat pear-shaped, light pink, VS2-clarity diamond ring, returned $US403,200 ($AU597,673).
