Material: turquoise bead, hand cut and hammered brass, 925 silver back Size: 2.2x1.2(cm) I find these Nepal turquoise beads really delicate and attractive. Soon after, I made this simple pair with some hand cut and hammered brass. Hope you like it as much as I do :-)\ Care and maintenance for brass jewelry All brass products from The Green Beetle are polished to prevent from tarnishing for most usage. However, exposure under water or oxygen (or contact with sweat, grease, lotion, etc.) still effects its shine. Here we provide four ways as reference: 1) Use a polishing cloth to rub your brass. 2) Use a toothbrush and gently brush some toothpaste on your brass, later, clean it with water and dry it after. 3) Mix some lemon juice with baking soda at 1:1 portion. Rub your brass with the mixture until it’s clean. In the end, rub it with a wet cloth and keep dry. 4) Dip a cloth with brass polish, then rub your brass with until it’s nice and shiny.
