The sisters kindly note that this product is only available online.The October Birthstone pendant is made from brass and is plated with 3 micron 18 karat gold as well as raw garnet. Every stone has a unique size and shape but usually measures 12-13 mm x 7-9 mm in length and width. The birthstone comes in a lovely, little velvet pouch including a descriptive card about what the specific birthstone symbolizes."Some believe that the garnet stone symbolises willpower, confidence and energy," says Anna with a smile. Anna and Clara kindly note that you should avoid direct contact with moisture and liquids for better durability of the gold plating. The sisters also recommend storing your jewellery pieces in a cool and dry place, preferably in a closed box. Furthermore, the sisters always recommend taking off the jewellery before showering, exercising and sleeping to protect its shiny surface.
