The button

The button is made of white metal. Its shape resembles an egg, with a thickness of 3.5 cm and a height of 5 cm, representing a hollow ellipsoid similar to a sphere. A vertical column runs along its length in the middle. At the bottom of the column is a tube measuring 1.5 cm in length and 0.7 cm in diameter, the edges of which are adorned with four rows of filigree patterns, surrounded by pressed ribbons. The pressed ribbons are located at the equator of the sphere, dividing the upper and lower hemispheres into four sectors and continuing at the poles (without filigree) in a ring. The sectors of the upper and lower hemispheres do not match each other. At the bottom of the sphere, the column, which is 0.2 cm tall, ends in a triangular (1 cm) pyramid made using the technique of granulation. The time period is the late 19th century to the early 20th century.
