Ornamental buttons made from seashell
One of the most important inventions of Idus Valey Civilization was the button. The Indus Valley civilization's Kot Diji era (c. 2800-2600 BC), the Tomb of the Eagles in Scotland (2200-1800 BC), as well as Bronze Age sites in China (c. 2000-1500 BC), Ancient Rome, and other places, all employed buttons, and button-like artifacts as seals or ornaments rather than as fasteners.
Buttons were first created in the Indus Valley Civilization to be utilized as ornaments for various events and activities, as opposed to their usual use as fasteners. These geometrically shaped buttons from that period were constructed with holes cut through them and were used to fasten some garments with thread. Additionally, some of the most expensive buttons were constructed from copper and alloys. However, during the Bronze Age, seashell regulators were famous and frequently utilized.
