An impressive 10.28 carats diamond single-stone ring by Van Cleef & Arpels is set to lead Bonhams London Fine Jewellery sale next month (27 April 2017).
The E colour marquise-cut diamond is set between pear-shaped diamond shoulders and is estimated at £150,000-200,000. Accompanied by an additional letter from GIA, the diamond has been classified as Type IIa, meaning that it has been recognised as the most chemically pure and with exceptional optical transparency.
Signed jewellery from the world's most famous houses will also be offered in the sale, which will consist of 141 lots in total.
Notable pieces include a highly desirable Diamond 'Fuchsia' brooch and earring suite by Van Cleef & Arpels. The brooch is designed as a fuchsia flower head, its petals pavé-set with brilliant-cut diamonds and its stamen reveals an articulated cascade of pear-shaped diamonds. Estimated at £70,000-100,000, the diamond suite, consisting of 27.05 carats, is set to appeal to collectors of period Van Cleef & Arpels, given the small quantities made.
Moving on to the 1920s, Bonhams is delighted to offer a striking Art deco diamond bracelet by Cartier for auction, estimated £20,000-30,000. Dated circa 1925 and signed Cartier Londres, the elegant and wearable bracelet is designed as a finely pierced articulated strap of geometric design, decorated with cushion-shaped old brilliant and single-cut diamonds.
Another iconic piece of jewellery featuring in the sale is An enamel and diamond 'Serpenti' bracelet-watch by Bulgari.
This is a rare surviving example of the famed Bulgari Serpenti design bracelet watch, circa 1965-1970. The highly articulated bracelet is composed of a series of overlapping scales applied with orangey-yellow and red enamel. The serpent's head features a forked tongue and marquise-cut diamond eyes, its mouth opens to reveal a circular watch dial.
Inscriptions are often found on the underside of the tails of Bulgari Serpenti pieces, referring to specific species whose skins inspired the enamel work. This particular example is of a 'Serpe dei Ratti Giallo', or a Yellow Rat Snake, and has a pre-sale estimate of £50,000-60,000.
Spotlight on spinels
Coloured stones are also expected to dominate Bonhams Fine Jewellery auctions in London and New York in April and in Hong Kong in May.
Bonhams London will be offering An early 20th century spinel and diamond ring for sale. Dated circa 1915, the step-cut spinel, weighing 5.30 carats, is set within an octagonal surround of old single-cut diamonds. Accompanied by a gemmological report, it states that the spinel is of Burmese origin, with no indications of heat treatment. With exceptional transparency and intensity of colour, it is estimated at £15,000-20,000.
Spinels have become increasingly collectable over the last few years, highlighted by the historic sale by Bonhams of The Hope Spinel, a 50.13-carat spinel, from the collection of London banker Henry Philip Hope, in September 2015 for a world record price of £962,500. Fine gem-quality examples are rare and when they come on the market they are extremely sought after by a growing band of collectors.
Bonhams has a long-held reputation for selling artist jewellery across the globe. In the UK, demand for pieces by Andrew Grima, John Donald and Stuart Devlin continues to increase with an expanding group of collectors. These jewellers created jewels where the value lay in their aesthetic composition rather than the carat weight of expensive diamonds and gemstones used.
Bonhams will be offering several pieces by Andrew Grima in its London sale.
• A gold, diamond and fire opal brooch/pendant, 1970. The oval-cut fire opal set amongst an abstract arrangement of textured 18 carat gold cinnamon sticks, with a brilliant-cut diamond accent. Pre-sale estimate: £5,000-7,000.
• A rutilated quartz, cultured pearl and diamond torque necklace, 1990. The textured torque suspending at the front a carved rutilated quartz 'apple' with brilliant-cut diamond highlights, surmounted by a grey cultured pearl and brushed leaves highlighted with brilliant-cut diamonds. This lot is accompanied by the limited edition exhibition catalogue, Grima, by Johann Willsberger, 1991, an original illustration of a necklace by Grima and a signature panel from Andrew Grima. Pre-sale estimate: £7,000-10,000.
• A colour change sapphire and diamond ring, 1977. The cushion-shaped sapphire, set within an abstract surround of brilliant-cut diamonds mounted on stalks, is estimated at £5,000-7,000. The sapphire is of Sri Lankan origin, with no indications of heat treatment.
Going even further back in time, Bonhams will also be offering a number of antique pieces for sale. These include:
• A 19th century diamond rivière necklace estimated at £60,000-80,000. Composed of 45 collet-set cushion-shaped diamonds weighing 43.00 carats in total. The diamonds graduate in size from the centre, the five largest weighing 2.35 carats, 2.30 carats, 2.08 carats, 1.96 carats and 1.91 carats. The necklace features a similarly set cushion-shaped diamond single-stone clasp, mounted in silver and gold.
• A Georgian diamond panel bracelet, circa 1780. A rare surviving example from the Georgian period. This bracelet is composed of a series of individually sprung plaques, each pavé-set with old brilliant-cut diamonds, within a border of similarly-cut diamonds, mounted in silver closed back settings. Estimate: £8,000-10,000.
• An early 18th century gold and diamond necklace, Portuguese. In its original fitted case, the necklace is designed as a series of ribbon-bow motif links suspending a chandelier fringe, emblematic of 18th century Portuguese jewellery design. Estimate: £10,000-15,000.
