Materials & Finishes
We believe that fine jewellery starts with genuine precious materials. We combine certified 925 sterling silver, solid jeweller's brass, multi-micron gold plating, and diamond-grade cubic zirconia to create pieces that feel luxurious and last for years.
Our Core Base Metals
Dense, durable, and completely free of toxic fillers.
Pure 925 Sterling Silver
Composed of 92.5% pure elemental silver alloyed with 7.5% copper for structural rigidity. Every silver piece is stamped with the official "925" hallmark, ensuring authenticated precious metal purity.
Hypoallergenic Jeweller's Brass
A specialized, dense copper-zinc alloy engineered specifically for fine jewellery casting. Unlike cheap pot metals or scrap zinc alloys, our brass delivers structural weight, smooth polishing, and zero allergic reactions.
Plating Mastery & Gemstones
Multi-layered coatings and hand-selected stones for diamond-like brilliance.
18K Gold & Rhodium Electroplating
We electroplate our pieces with genuine 18K yellow gold, rose gold, or platinum-family rhodium. A final invisible nano-ceramic sealant creates a protective barrier against moisture, skin oils, and ambient humidity, preventing premature tarnishing.
5A Cubic Zirconia & Freshwater Pearls
Our stones are top-tier 5A brilliant-cut diamond simulants with exceptional clarity and optical dispersion. Our pearls are hand-selected cultured freshwater pearls with thick, luminous nacre and natural organic silhouettes.
100% Safe for Sensitive Skin
All NUNSOO pieces comply with international REACH standards and are independently tested to be 100% lead-free, nickel-free, and cadmium-free. Wear your favourite pieces all day in complete comfort with zero skin rashes or discoloration.
