Spoon (6) - .800 silver - 6 Siréne coffee spoons

6 Sirène spoons in 800-grade silver, gold-plated with fine gold and set with a pear-shaped topaz 6x4 mm, with its lacquered mother-of-pearl box labeled "Duc de Guise" — my former company; now retired, I am selling my personal stock.
*In an art foundry and hand-chiseled, polished for each piece, which requires 1 day of work for each spoon, and furthermore the bezel setting of the Topaz at my jeweler.
I gave as a wedding gift in 2011 the same Sirène spoon to the couple Albert II of Monaco and Charlène Wittstock — Sold on Fifth Avenue in New York — London and Paris.
The 6 spoons in silver weigh 150 grams with their certificate of authenticity. There were only 50 spoons in the world.
