Except for spinels, turqouise, emeralds, rubies, pearls and diamonds, it is rare to find other kinds of gemstones in the treasury. These two bracelets are the exception.
The top bracelet is probably of Russian origin. The simple gold band and frame of diamond and pearl highlights the exceptionally clear red garnet stone, weighing 70 cts.
In the bracelet below, the center stone is a 35 ct. sapphire. The stones to the left are a 20 ct. tourmaline and an sardonyx, and the stones to the right are a 25 ct. chrysoberyl and an onyx. The stones are framed with diamonds.
