So neither Greek nor Roman, but from Iran, Suse and around (see map above)
but I'll post some later on ... keep checking
the answer is by order of age :
1 - necklace : said to be -3300 to - 3100 BC, found in 1929, from Uruk, Suse
2 - bracelet : -2600 to -1700 BC found in 1908 in Suse (Fasciolaria Trapezium or a Xancus Pyrum shell)
3 - rings : said to be as old as XIII to XII s BC, from Medio Assyrians, Mari civilisation
That's what Caitlin tells us in History of pearls :
Pearl History of Persia
Pearls from the Gulf of Persia have been known for at least 2,700 years, not through the written word, but sculptures and coins. The gulf pearl beds were arguably the oldest, and largest, ever known. There was no other place in the world where pearl oysters grew more and better pearls, or where it was possible to dive for pearls in more places, than in the relatively warm, shallow waters of the Persian Gulf, with its many fresh water springs. Possibly the oldest pearl necklace still in existence comes from ancient Persia, from a 2,400 year old Queen's tomb. Known as the Susa necklace, it has 3 rows of 72 pearls each, held with spacer bars. This design is one of the oldest pearl necklace styles. The Susa necklace has been shown in the Louvre’s Persian gallery, for over 100 years.
Now at last here are the pearls, see the delicate gold work and mixing with stones
Where is this jewel from and how old is it ?
Still on the hunt ?
