Material: Brass, 925 silver post, MIYUKI seed beads Size: 6 x 1.5 cm *All works of The Green Beetle are made by hand. Unlike machine manufactured products, handmade gives a unique touch to every piece of work. About the Earthy loop studs The structure of this pair is rather light and thin, which is the best choice for you if you like light-weighted earrings. I made the beading with Japanese imported seed beads with ceramic texture and brass beads to give an earthy, elegant look. 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.
