Committee spokesman Vladimir Markin said today that the jewellery, worth more than 126 million rubles (USD 3.9 million), was discovered at the home of Yevgenia Vasilyeva and "returned to the state."
Vasilyeva was charged in 2012 with fraud related to the sale of military assets, then said to be worth about USD 11 million.
Russia's military investigators announced Tuesday that they are now estimating the total damage at about 3 billion rubles (USD 93 million).
The nation's military establishment has been haunted by corruption accusations for years.
