Please note, every pearl has it's own unique shape.
"Gold filled" ( or "rolled gold" ) comprises a solid layer of gold (14k) permanently bonded to a base metal, such as brass. The minimum layer of gold must equal at least 1/20th the weight of the total item. It is very hard wearing and under normal wear the gold will not peel or flake, unlike gold plate, and is commonly used as a more economical alternative to pure gold.
*Please note, due to natural variation in the pearls, those purchased may slightly differ from the picture
