Features Primary Material : silver Inside Diameter (mm) : 70 and 75 One of a Kind : No Metal : sterling silver Hallmarked : Yes Finish : textured satin Cleaning InstructionsWe suggest silver dip or silver cloths for cleaning our work. At Latham & Neve we use silver cleaning dips and cloths from Town Talk, an established British company renowned for their quality products.For cleaning stubborn areas and recesses dipping a cotton bud or an old soft tooth brush in silver dip is usually effective. On matt/satin and textured surfaces we also recommend cleaning with a soft tooth brush with silver dip or alternatively a small abrasive pad can be used (ensure all recesses of the jewellery are clean and dry).
