Here is a treasure… an amethyst and diamond necklace made c.1915 in Russia, featuring a deep purple Siberian pear-shaped amethyst framed by old European-cut diamonds set in silver over gold.
You know the story here – silver (and later, platinum) was used for setting diamonds, so that the ice white colour wouldn’t be yellowed by a gold setting.
This is a special piece, as Siberian amethysts are no longer mined. They can only be found in antique jewelry, or vintage jewelry from the 1930s-1950s.
The necklace is sold, and this information is from the archives of Romanov Russia... but never fear – the website still has a plentiful supply of beautiful jewels for sale.
The amethyst measures 16.4 x 18.7 x 9.4 mm and is approximately 13.75 ct.
Estimated total diamond weight is about 3 carats.
The necklace is marked with 56 zolotnik Imperial gold standard and later Soviet control mark from the 1930s for 583 gold standard. It comes in D. Osipov, St. Petersburg retailer’s case of the period.
Length of the pendant 48 mm (1 7/8 in.)
Length of the chain 42 cm (16 1/2 in.)
