Larkin now has these sword rings with either garnet or blue cubic zirconia gemstones! Larkin has chosen to source lab-created gems rather than natural gemstones because laboratory conditions are fairly well controlled, while the gem mining and cutting industry is vastly unregulated with many workers dealing with inhumane conditions. This is also why Larkin is moving towards working almost exclusively with stones found by themself, friends, or family.
Larkin is hoping to save up for a faceting machine so they can shape their own fancy sparkles from self-found stones!
