Other highlight diamonds on offer is lot 205, a pair of diamond single stone earstuds, the brilliant-cut diamonds each weighing approximately 1.1 carats in claw mounts.

Lot 79 : A 19th century Russian gold and malachite bracelet

The sale also includes a very nice example of Russian jewellery. Lot 79 is a 19th century gold bracelet set with cabochon malachite panels.

The bracelet has Russian gold 56 guarantee mark and town mark for St Petersburg. It comes with a pre-sale estimated price of £1,000-£1,500.

  Lot 81 : A 19th century archaeological revival, silver-gilt and bloodstone necklace by Carlo Giuliano

Lot 81 : A 19th century archaeological revival, silver-gilt and bloodstone necklace by Carlo Giuliano

(lot 81) Another interesting antique item included in the sale is a 19th century archaeological revival, silver-gilt and bloodstone necklace by Carlo Giuliano, which comes with an estimate of £600-£800. The necklace is composed of faceted bloodstone graduated beads, with shaped gilt bead dividing links and reeded pyramidal shaped spacers to a later S shaped clasp, unsigned due to later clasp, however the necklace is housed in original maker's octagonal fitted case stamped K for C.J. Kitts. c. 1870. Referring to himself as an artist jeweler, Giuliano’s clients included a number of famous Pre-Raphaelite artists of the day. The most famous set of jewels was commissioned by Sir Edward Poynter for his famous depiction of Helen of Troy. Although the fabled jewels of Helen were believed to have been discovered by Heinrich Schliemann in 1873 and were well known to Giuliano who had catalogued the collection for the archaeologist, Poynter preferred to commission a suite of silver-gilt archaeological inspired jewels as more befitting the Heroic personification of Helen. The necklace in the sale can be compared to the bloodstone and gilt featured on page 82 of Artists’ Jewellery, Pre-Raphaelite to Arts and Crafts. Charlotte Gere and Geoffrey Munn, Woodbridge, Suffolk, 1989.
