Superb 15k Georgian to Victorian Era Mourning Jewelry, Facet Cut Jet Gems or Onyx, Hair Art

A sweet little mourning pin I found ages ago in London, this is 15k gold, high quality as evidenced by the closed back, set with facet-cut jet gems in varying sizes on the perimeter of a plaited hair art memento under rock crystal cover ‘glass’.  Full measurements noted on photos. 12k – 15k 2.26 grams.

Very good to excellent condition for age and type. I find no stones missing, and no repairs or losses. A slight dent to the 15k gold backing, very tiny. Dark blond hair inside, a little dust capturing the photo lights more than in person.
