This 18k yellow gold necklace is made up of 18 crescent moon-shaped onyx panels, all fitted in yellow gold settings. The central pendant is also made up from several crescent-moon shapes and terminates in a tear-shaped drop.
The necklace carries the hallmark -depicting the papal crown and two crossed keys- of the Vatican Workshop, which was founded in 1727, originally to restore the existing mosaic artworks around St. Peter's Basilica. Over time, the workshop started creating jewellery for the growing group of wealthy Grand Tour visitors to Rome, who wanted to bring a souvenir back home from their travels.
The workshop specialised in micro mosaic jewels and their jewellery is considered rare and collectible today. I suspect this necklace was created for someone in mourning since it is made from onyx (the background for most micro mosaics) but lacks any further decoration or colour.
General Information
Size: 36 cm / 14.15 inches long.
Please note: This necklace will be short for many people, so double-check your size before purchase. It could be lengthened by adding two fine gold chains: feel free to reach out if you would like to discuss this option.
Weight: 5.40 grams
Age: 19th Century, circa 1860.
Material: Acid tested as being 18k gold, and hallmarked for the Vatican Workshop.
Condition: In antique condition with only minor signs of wear, consistent with age. One onyx has a chip; this can be seen on the pictures. The original lock is broken and I therefore had it replaced by a similar looking antique example: I can include the original lock with your purchase if desired.
Please note that the antique box is for display purposes.
