RAPAPORT... Bonhams will spotlight a rare square-cut, 5.03-carat, fancy-pink, VS1-clarity diamond as well as a tiara owned by the family of Winston Churchill, at the auction house’s fine-jewelry sale in London in late September.

“It is extremely unusual to find a pure pink diamond, of even saturation, with no secondary component colors, weighing over 5 carats,” said Emily Barber, Bonhams UK director of jewelry. The auctioneer valued the stone (pictured) at approximately $777,380 to $1 million (GBP 600,000 to GBP 800,000).

Also going on sale is a fancy-colored, three-stone diamond ring, featuring an old-brilliant-cut, 0.95-carat, fancy-blue center stone, surrounded by two marquise-cut, 0.51-carat and 0.56-carat, fancy-yellow-orange diamonds. The presale estimate for the piece is about $103,650 to $155,480 (GBP 80,000 to GBP 120,000).

Other notable pieces include two diamond tiaras: a geometric, Art Deco tiara/necklace/brooch combination by Hennell, belonging to the Churchill family and estimated at approximately $51,830 to $77,740 (GBP 40,000 to GBP 60,000), and a Belle Époque tiara designed by Spanish royal jeweler Ansorena in the Greek meander style. The headpiece, which belonged to the countess of Villagonzalo, has an estimated selling price of around $103,650 to $155,480 (GBP 80,000 to GBP 120,000).

Jewelry from Cartier, Van Cleef & Arpels, Bulgari, and Chopard will also go under the hammer, including a diamond necklace by Cartier carrying a presale estimate of about $259,130 to $388,690 (GBP 200,000 to GBP 300,000).

The London Fine Jewellery sale will take place on September 26.
