A pear-shaped brass and Mother of Pearl trinket box with twist-off top to reveal a shallow storage area inside. The pear measures 3" across and 5" high. The maker is unknown and the condition is good, with no defects to the Mother of Pearl and a naturally aged patina to the brass that can be polished to a shine.
Mother of Pearl, also known as Nacre, is a material secreted by the epithelial cells of the mantle tissue in oysters and other mollusks. The material is continuously deposited onto the inner surface of the shell, the iridescent nacreous layer, which helps defend the mollusk's soft tissues against parasites and debris by entombing them in successive layers of nacre, forming either a blister pearl (attached to interior of shell) or free pearl.
