Jet, a flat-black, opaque gemstone derived from wood that has experienced extreme compression over millions of years, was the haute stone throughout the Victorian era, a time when fashion and jewelry deftly signaled a person’s social status, financial wealth and even emotional state. Victorian dress was rife with symbolism and evolved around rigid codes of propriety and caste. Tightly pulled corsets and top hats, to name two ubiquitous items from the era, signified wealth and propriety, while jewels depicting doves hinted to an individual’s deep religious devotion.
