Real Jewelry…diamonds, high karat gold, precious stones (Emeralds, Sapphires and Rubies) are high value, low weight, easily transportable, hidden wealth that may be concealed, used to buy one’s way to freedom, greasing the palm of a border or prison guard or visa granting official.
My family may have arrived in the USA back in the late 1860s and early 1870s, but until my parents bought their first house in 1951 always rented and kept gold and jewels on hand should an instant flight be necessary as was too often the case in Europe. My generation all own real estate, but all keep ready gold, gems and cash in easy reach should the need arise.
