Special patented anti-tarnish technique applied: Abiding Shield contains 2 layers: Gem Film ( SiO₂): 360° full covered, separate the jewellery from oxygen; Self-cleaning Film: Lotus Effect, Silky Smooth, Aging Resistance.
This patented anti-tarnish technique has been demonstrated in laboratory tests to significantly prolong the durability of gold/platinum plating for several years. This stands in clear contrast to the typical lifespan of most gold/platinum plating, which usually only endures for a few months.
Black gold plating for jewellery involves mixing yellow gold with cobalt in a precise three-to-one ratio. This process requires additional procedures and sophisticated techniques to achieve the distinctive black colour while retaining the presence of real gold.
