Fantastic Whitby jet earrings in the form of concentric circles, a classic geometric shape that we love. The material is made of Whitby Jet, a form of fossilized coal that came from the coal mines of Whitby England in the 18th and 19th centuries. Jet was especially popular during Victorian times because it was acceptable as a form of mourning jewelry. Jet is particularly appealing as a material for crafting jewelry because the material is lightweight and can be carved and polished to a beautiful shine, and looks pleasing against any skin color. Our earrings are over an inch wide at their widest point and approximately 2.3 inches long and are hung from gold ear wires. They are ideal for casual wear or a as part of one's professional wardrobe. Jet is a material that will always be treasured and you will stand out with these fabulous earrings.
