NEW YORK – An Art Deco-style platinum brooch sporting eight carats of diamonds, an 18K white gold and diamond cocktail ring, and a 14K gold and diamond ring set with a GIA-certified 5.12-carat emerald will compete for top lot status at Jasper52’s Classic to Modern Gold and Diamond Jewelry Auction, which will be conducted on Wednesday, February 1 at 8 pm Eastern time. Absentee and Internet live bidding will be available through LiveAuctioneers.

The February 1 sale contains more than 500 lots, and several feature familiar stones in less common hues. Examples include an 18K gold ring with a GIA-certified piece of purple jade; a 14K white gold ring boasting a GIA-certified 3.15-carat unheated yellow-orange sapphire; and an 18K white gold cross pendant festooned with nine carats of Ascher cut pink sapphires.

Other lots in the sale that contain GIA-certified stones are a pair of 14K white gold earrings with natural royal blue sapphires that together weigh 7.81 carats; an 18K gold bracelet with 23.46 carats’ worth of vivid red rubies; a natural orangey-pink morganite of 36.18 carats, set in an 18K rose gold ring; and an unset emerald-cut aquamarine that weighs a whopping 46.87 carats.

There is also a strong selection of tennis bracelets, among them a classic-looking 14K white gold piece with 7.70 carats of round cut white diamonds; a 14K gold bracelet with almost 20 carats of rubies; and a 14K white gold example with rubies, diamonds, emeralds, a green garnet and sapphires in shades of blue, yellow, pink and orange.

The first of the aforementioned highlights, a platinum brooch with eight carats of diamonds, has an abstract, undulating style. The stones are G-color and vs-2 clarity; some are round cut, some full cut and some brilliant cut; and the brooch can be repurposed as a pendant. The piece is estimated at $12,000-$14,000.

The 18K white gold and diamond cocktail ring is a classic princess channel band set with two carats of baguette cut diamonds and .46 carats of round diamonds of Vs-2 clarity and G color. Its estimate is $4,000-$5,000.

The 5.12-carat emerald in the 14K gold ring is natural, has a strong, deep green color, and is, sensibly enough, in an emerald cut. It is surrounded with 1.20 carats of round cut and full cut diamonds of Vs-2 clarity and G color and carries an estimate of $27,000-$32,000.
