The turtle is a symbol of longevity and patience, center of this focal element that has a modified ceramic flat bead aged to fit into the design style as an imaginary ancient piece valuable or meaningful like to set as talisman. Dangles with Indonesian beads that mimik -they are Good countarfeit makers, fooled hundreds with their reproductions and just collectors know how different they are- ancient and trade beads made to fool turists and inexperienced buyers in a quest for ancient beads. -If cheap, is probably a fake. Ancient beads depending on how rare can cost to thousands a Piece, nor a strand...-
The feather? It is from a Blue Jay, I take care of a feral cat colony -trap/fix/release/ veterinarian attention, food, water, shelter- but also after the winter storm that killed lots of plants and food for wildlife I started feeding "all critters", and as my cats have a large catio and will not be able to reach them and feral and stray cats have not access to my back yard I can feed squirrels, birds, even opossums, skunks -Lol, hey they are cute, and will not do the stinky thing if they feel safe-, racoons, and whatever needs some food and water and some sheltering during the harsh summer or winter. This feather is from one of the Blue Jays we feed every morning -like USPS  slogan: rain, snow, storm, heat, cold... every day, hahaha- properly sanitized, washed with alcohol, etc. A gift from nature given freely, no better Karma -Dharma?.-
Super indigenous looks
It measures total no counting the floating bail nor the feather approx. 4 inches x 1 3/4 inches -measuring just copper circular frame and top bail but not floating bail: 61 x 45mm.-
