A piece of jewelry that has lost its shine is not a damaged piece of jewelry; it is a normal phenomenon that is easily corrected with the right care, provided you adapt your methods to each material. Here is how to maintain your jewelry, such as the Notte necklace, the Acqua necklace, or the Sunrise necklace, without risk of damaging them.
Two materials, two levels of maintenance
Before cleaning a piece of jewelry, it is helpful to know what it is actually made of, as not all parts react in the same way:
- 925 Sterling Silver: the diamond-cut beads, the wire supporting the fine stones and pearls, and the clasp. Solid silver handles thorough cleaning well, including occasional immersion.
- Silver-plated brass: the chain. This is brass covered with a thin layer of silver on the surface (plating, not solid metal). This layer can wear down over time if scrubbed too hard, immersed for too long, or exposed to harsh products; it therefore requires more delicate handling than solid silver.
In both cases, the darkening observed is the same phenomenon: the oxidation of the silver surface upon contact with air.
Why silver darkens over time
Whether it is solid silver or a layer of silver plating, this metal reacts naturally to contact with air: this process is called oxidation, and it manifests as a grayish to black tint that appears gradually on the surface of the jewelry.
This process is accelerated by several everyday factors: contact with the skin (perspiration levels vary from person to person), perfume, lotions, swimming pool chlorine, or seawater. It is not a manufacturing defect, but a natural chemical reaction of the metal that requires closer attention on plating, since once the silver layer wears away, the brass underneath becomes visible.
Simple cleaning for regular maintenance
For routine maintenance, the same method is suitable for the entire piece:
- Gently rub with a soft, dry cloth, ideally microfiber, to avoid micro-scratches.
- Apply light pressure on tarnished areas, without scrubbing too hard, especially on the silver-plated brass chain.
- Perform this action after each wear, before storing the jewelry.
This quick, regular cleaning prevents oxidation from taking hold deeply and limits the need for more thorough cleaning; it is also the safest way to preserve the plating on the chain over time.
Thorough cleaning: adapting to the material
When the darkening is more pronounced, the procedure differs depending on the part of the jewelry:
For 925 Sterling Silver parts (beads, wire, clasp):
- Prepare a bowl of warm water with a few drops of mild soap (like liquid Marseille soap, without harsh perfumes).
- Submerge the piece for a few minutes.
- Gently scrub with a very soft-bristled brush (an old toothbrush works well) to reach corners.
- Rinse with clear water and dry immediately with a soft cloth.
For the silver-plated brass chain: Avoid prolonged immersion and repeated brushing, which accelerate the wear of the plating. Use a slightly damp soft cloth rather than a bath, and dry immediately. If the chain is connected to solid silver parts of the piece, clean the entire item using the gentler of the two methods—the one adapted for plating—to be safe.
In all cases, never let jewelry air dry: residual moisture promotes oxidation.
Methods to absolutely avoid
Some methods, sometimes recommended on the internet, can actually damage your jewelry:
- Toothpaste: its abrasive effect can scratch silver and prematurely wear down plating.
- Scrubbing directly with baking soda: too abrasive for repeated use, especially on a silver-plated brass chain.
- Undiluted ammonia-based products: too harsh, they can tarnish certain finishes and attack plating.
- Prolonged contact with hot water: it can weaken certain stone settings and accelerate the wear of plating.
