Rare jewelry and watches to be auctioned off in mid-November by Christie’s Geneva will be exhibited today and tomorrow in Athens at the Hotel Grande Bretagne. The jewelry includes pieces from the Belle Epoque, Art Nouveau and Art Deco periods by such prestigious names as Cartier, Belperron, Boucheron, Lacloche, Lalique, Tiffany and Van Cleef Arpels. One of the highlights is a diamond, rectangular-cut, vivid yellow ring that weighs 10.39 carats (estimated at 550,000-700,000 euros). Other gems include a diamond single-stone ring by Graff and a sapphire ring of Burmese stone. Also available is lower-priced diamond jewelry estimated in the range of 4,000-6,000 euros. An emerald and diamond bracelet from 1925 (estimated at 40,000-50,000 euros) and an art deco pair of Cartier diamond lorgnettes (8,000-12,000 euros) are other examples of a diverse range of jewelry that reaches up to the contemporary period. Also on view are 50 pocket and wristwatches. One of the most impressive pieces is a rare Rolex, 18k gold, self-winding triple calendar wristwatch with phases of the moon and stars dial, manufactured around 1950. Roughly from the same date is a rare Patek Philippe chronograph wristwatch with a two-tone silver dial. The selection includes watches by Vacheron Constantin, Audemars and Breguet.
