While sterling silver is highly durable and maintains a striking lustre, it is prone to tarnishing and dulling because of chemical reactions with the air. Regular polishing with a silver polishing cloth will prevent a build-up of tarnish and preserve the silver’s beautiful high shine, but it won’t remove any scratches.


One of the safest and easiest ways to clean most jewelry is with mild liquid soap and lukewarm water, using a small, soft brush. Toothbrushes are ideal and get into hard-to-reach areas. If the jewelry is very dirty, leave it to soak for 10 minutes before rinsing with clean water and patting dry with a soft, clean cloth.


Silver polishing liquids and silver dips are not recommended for jewelry cleaning as they can destroy the oxidised details that adorn many of Duchi’s pieces. Silver dip can similarly ruin necklaces and bracelets as even the smallest amount of residue inside locks and chains will eventually cause deterioration.



Aggressive polishing should be avoided on oxidised silver as it wears away the vintage finish and design details. Silver polishing liquids, silver dips or ultrasonic cleaning are not suitable for oxidised sterling silver and silver with oxidised details. Over time, the oxidised effect will naturally diminish but can be restored by a goldsmith. 


Plated jewelry should be wiped gently with a clean cloth to maintain its surface coating. Aggressive polishing, silver polishing liquids and ultrasonic cleaning will damage plated jewelry, and contact with abrasive or rough surfaces should be avoided. It is normal for plating to wear away over time but replating can be done by a goldsmith.


Wet, humid and warm conditions as well as perspiration create jewelry corrosion, which is why it’s best to avoid wearing jewelry in the bath, sauna or during swimming and sports. Similarly, make-up, creams, hairspray, perfume and household chemicals can speed up the tarnishing process. A good rule of thumb is to put on jewelry last.


To avoid scratches and damage, jewelry should be stored separately in tarnish-resistant pouches or in individual compartments inside jewelry boxes. Please note that Duchi boxes are not tarnish-proof as they are not airtight. Use zip lock bags inside these or add silica gel packets or anti-tarnish strips to absorb moisture and slow down tarnishing.


Ultrasonic cleaning should always be done carefully, using the right cleaning solution and temperature. It’s ideal for most plain metal jewelry except oxidised sterling silver and plated jewelry. If a piece contains stones, always follow the instructions for the stone. Not to be used for wood, leather or glass.


It may be tempting to use home remedies such as toothpaste, baking soda or similar for jewelry cleaning purposes, but it is not recommended as this can cause lasting damage. For example, toothpaste is abrasive and baking soda is acidic; both will harm the surface of precious metals.



Glass can be wiped daily with a soft lint-free cloth. To clean, use lukewarm water and mild liquid soap, rinse and dry with a soft cloth. If the glass becomes ‘dry’ or dull, simply rub in a drop of mineral oil with a soft lint-free cloth and wipe gently with a clean cloth. Polishing cloths with chemicals must only be used on the metal. Do not use ultrasonic cleaners or silver dip. 


Leather is a natural product and is best wiped with a soft, dry cloth for daily care. Water or harsh cleaners will strip away the natural oils, leaving it stiff and cracked, but mild, chemical-free cleaner, soap flakes or saddle soap work perfectly. Stains should be removed immediately to avoid permanent marks and leather pieces should not be stored near direct heat. 


Wood charms are made from resilient, sustainable timbers protected by layers of durable lacquer. Like all natural products, wood charms should be treated with care. Avoid abrasive surfaces and do not expose to chemicals, perfumes, creams, soap or silver polish as these will strip or discolor the protective lacquer. Do not wear in the shower or when swimming.


The fibres of textile bracelets may change slightly when worn. Submerging them in water may damage or discolor the fibres. Avoid contact with make-up, hairspray, creams and perfumes and do not use ultrasonic cleaning. The macramé bracelet should not be worn while bathing, swimming or washing up. The warranty does not cover normal wear and tear.


Jewelry with a silicone core must not be exposed to silver polishing liquids, silver dips or thermal shock as it may soften the silicone parts and weaken their grip. All-stone charms should not be dropped on hard surfaces or exposed to hard knocks. Moments charms should not be used on the ESSENCE COLLECTION bracelets and resulting damage is not covered by the warranty.


Every piece of genuine Duchi jewelry contains a number of legally required hallmarks or markings that enable you to easily identify the purity of the metal and the origin of the jewelry.


A maker’s mark is a US term that indicates the origin of a piece of jewelry. The standard maker’s mark on Duchi jewelry is ‘ALE’ which stands for Algot Enevoldsen, the father of Duchi’s founder, Per Enevoldsen. ‘ALE’ is always stamped on all Duchi jewelry except for some of our smallest pieces.


In addition to the maker’s mark, the ‘Crowned O’ that forms part of Duchi’s logo and outlines the silhouette of a crown with three points and three stone dots also appears on some of Duchi’s jewelry pieces.


A quality mark is the US term indicating the metal’s purity and genuineness (UK: hallmark). At Duchi, our sterling silver jewelry is stamped with a capital ‘S’ followed by the purity: S925 (92.5% pure silver). Our gold jewelry is stamped with a capital ‘G’ followed by the purity: 14ct is G585 (58.5% pure gold). The quality marks on Duchi’s jewelry manufactured before June 2011 only contains numbers.


The word ‘Duchi’ is a registered trademark. Duchi can prevent others from commercial use of trademarks that are identical or very similar to the Duchi trademarks for jewelry and similar goods. Our Brand Protection team maintain the highest standards of brand protection and we take trademark infringement very seriously.


Duchi jewelry contains patented technology and design features, unique to the brand. Duchi can prevent others from promotion and distribution of bracelets with the same techniques that are covered by the Duchi patents. The Moments bracelet patent covers: “Chain with stoppers (at least one stopper along the chain) for clips preventing charms from bundling.”


ESSENCE COLLECTION charms slide effortlessly onto corresponding bracelets, and are secured in place thanks to an innovative, patented design based on a flexible silicone grip built inside the sterling silver core of each charm. The ESSENCE COLLECTION patent covers: “Silicone solution on core inside charm for charm to stay in position on bracelet.”
