One of the more fascinating aspects of ring design and motifs in the early 19th century is the increased use of gems and stones. What had previously been relegated to fine jewels was becoming ubiquitous and taking over as a symbolic motif in their own right.
Pearls are the most popular and common to find in rings (many bracelets were strung with pearls, but surviving pieces are harder to find). Jet and turquoise are two of the other most popular materials and are important for their use in mourning custom and symbolism.
Second and third stage jewels took very well to the enhanced use of colour, as reflective surfaces and colour were permissible, so hairwork jewels flanked with stones were not only an essential part of mourning, but a beautiful way to reflect and respect the loved one.
These became prevalent from around 1810 and lasted well into c.1850, where larger, bolder styles and black enamel facilitated the changing fashion.
