In certain cultures, black is the colour of mourning, worn to funerals and traditionally during the formal grieving period.

Jet, also known as lignite, is a type of coal that forms over Millennia from highly pressurised wood. It can be carved and polished to have a glass-like finish.

The Crown jewellers crafted commemorative black jewellery for Queen Victoria's mourning, leading to a surge in demand for Whitby jet by the 1870s.
