Late Victorian Pearl Cross/Sheaf Locket

Jet Pearl Locket

Vulcanite, Jet and the materials to represent the same styles are many of the most misinterpreted in mourning and sentimental jewels of the 19th century. One thing that is important to note is that jet wasn’t simply a mourning material, which is often a common misconception. It was another jewellery material and quite fashionable, hence giving tokens made from jet doesn’t in any way denote death. Often its black nature and use in early stage mourning gives the impression that it automatically defaults to death. However, brooches from the 1870s, pendants, lockets, trim, beading, necklaces and personalised mementos (such as pins) are quite commonly found as love tokens and items held in high fashion, with only a small percent being used directly for mourning. Jet was also used as a secondary material in many rings, such as jet beading surrounding a ring’s hair memento, creating wonderful embellishments. The ability for jet to be highly polished made it a lustrous and attractive material.

One of the problems with jet come from the multitude of imitations made to replicate it. Once can discover the origins of a jet piece, as it produces a brown streak when rubbed against porcelain, is warm to touch (as it is a poor conductor of heat and a glass imitation would be cold in comparison) and if you heat a needle and put it to a piece, it will give off the faint smell of sulphur. Look for imitations of jet where the piece looks like it’s moulded – jet was carved and couldn’t take the obvious rounded shapes of horn or Vulcanite.

Vulcanite was patented in 1846 by Goodyear (the same tyre manufacturer of today), as the patent specified a manner of mixing rubber and sulphur, then heating the mixture to one hundred and fifteen degrees Celsius. It produces a brown powder when scratched and has a faint odour of sulphur. Often, a vulcanite piece in good condition can be hard to discern from actual jet, but one of the signs to look for (next to burning it with a needle and checking for the smell – Jet smells of coal) is to look at the design and note if the piece is obviously moulded (such as the smooth, curved expanding band on this piece) or if there are the obvious carving marks.

Often called ‘ebonite’, vulcanite was the most mass-produced rival to actual jet. Its ability to be moulded and not carved, along with a relatively low cost vs. labour to manufacture made vulcanite a material that was accessible to middle and lower classes of the 19th century, especially at a time when actual jet was the height of fashion. However, vulcanite, like other plastics has been seen to devalue the real thing.

Vulcanite could withstand high polishing and show a high gloss lustre in the same way as jet, but over time, the fading to khaki from black is a tell-tale sign. Vulcanite has a relatively low tolerance to sunlight so, finding pieces in their original condition isn’t hard (as there were many thousands of pieces produced), but it is becoming more difficult.

When buying jet or vulcanite, be vary wary and scrutinise your piece closely. One of the easiest ways is to spot the carving behind the memento (photo or hair) in a locket, as this wasn’t smooth and moulded like vulcanite, jet will often show the marks of the carver’s tools.

With this jewel, we see a seed pearl inlay in a wheat and cross motif. On the back is a glass compartment which likely would have contained hair of the loved one.
