How to use recommendations for jewelry care:

1. Open the card of the jewelry you like and read the description carefully.

2. In the "Materials" section, you will find out what the decoration is made of.

3. Pay attention to the type of metal and the words "enamel", "lacquer", "epoxy", "patina", "pyropatina".

4. Follow the instructions below when using and caring for your jewelry. 

We recommend the following care guidelines. Failure to follow the care recommendations may reduce the product’s lifespan, but does not affect your statutory rights.

 

​

 

Copper

 ​

 Cleaning ​

Сlean your jewelry at least once a month, and to wipe it when you remove it from your skin or clothing, especially before storing it in a jewelry box.

​​

​

The jewelry is patinated

but not lacquered, enameled or epoxy-coated.

​

- Gentle dry cleaning: 

a) Use a soft toothbrush or a flannel. Carefully polish only the protruding parts. This will refresh the shine of the copper, but the blackening in the depressions will remain.

b) Polishing cloth (rub them with a rough cloth until they shine: felt, wool, denim, flannel, and suede are suitable for this purpose).

​

- Cleaning with soap solution

Dilute a little mild soap (no abrasives, no bleach). Quickly rinse the jewelry in the solution, using a soft brush to remove dirt.

Immediately wipe thoroughly dry and dry.

​

- Polishing wipes for jewelry

Special cloths impregnated with polishing compounds are sold. They remove the deposit only from the surface and hardly touch the patina.

​​​

!

Many methods of purifying copper (for example, citric acid or vinegar) are not suitable for cleaning jewelry due to the risk of aggressive effects on the stones contained in these products. Some stones don't even tolerate water well.

Do not a metal brush or other abrasive tools to clean copper jewelry, as these tools will remove the patina (special blackening or pyro-patina created by fire).​

​​​​​​​​

​​​

​​The jewelry is coated

with enamel, or epoxy resin.​​

Epoxy resin protects copper from oxidation, so the main task is to protect the coating, rather than trying to "polish" the metal.

​

- For easy cleaning (dust, dirt, fingerprints)

Soft dry microfiber or suede cloth. Gently wipe without pressing.

​

- If there are greasy stains or dirt

Weak soap solution (liquid soap or mild shampoo, without alcohol or bleach). Wet a soft cloth or cotton pad, gently wipe the surface. -Immediately wipe dry with a soft cloth.

​

 - For shine and protection

Use special jewelry wipes for coated items (they are soft and non-abrasive).

You can also use microfiber cloths to clean your glasses.​
 

!
Sun and heat – ultraviolet light accelerates yellowing and aging.

Chemicals – perfumes, alcohol, deodorants, acetone, detergents.

Sudden temperature changes – from frost to heat, the resin may crack.

​

​​​​​​​​

The jewelry is varnished

​

This jewelry can contain both patina, enamel, and epoxy resin, but it is coated with a protective layer of varnish.​​​​​​​​

 - Gentle dry cleaning: 

Wipe the jewelry after wearing with a soft, dry cloth.

​

!

Take it off before showering, bathing, or exercising.

Ultraviolet light and heat accelerate the aging of resin and varnish.​​​​​​​​​​​

Avoid chemicals – perfumes, creams, detergents, alcohol solutions destroy the varnish and resin.​​

​

​​

​

​

Jewelry

storage:

​

- store jewelry separately from each other, preferably in a closed box, sealed bags, a casket or at least in a zip-bag

- away from heating devices and direct sunlight.

- you can add a bag of silica gel or a piece of chalk.

- when transporting, it is advisable to fix or pack the product tightly.

!

When stored in humid rooms (bathrooms, kitchens), copper may turn green over time.

When storing jewelry in boxes or drawers with other items, jewelry can bend or scratch the epoxy layer.

​​

​

​

How to wear

copper jewelry properly 

​

- Wear your jewelry only after applying makeup, perfume, and creams (chemicals can accelerate the oxidation of copper)

- If your jewelry gets wet, wipe it dry or gently dry it with a hairdryer.

- Remove your copper jewelry before going to bed, as this will reduce the contact between the jewelry and your sweat.

- Wear on clothing, not directly on the skin (if possible) – reduces contact with sweat.

- Wipe with a soft, dry cloth (microfiber, suede) after wearing – removes sweat and grease.

​

​​​​

The effect of copper

oxidation on metal and body

 

 What happens to copper:

 

During oxidation, copper becomes covered with a green or dark coating (copper oxide, "patina"). This does not mean that the product has deteriorated — many people appreciate such noble aging. However, plaque can stain the skin.

 

What happens to the body

 

Greening of the skin (more often on fingers or wrists) is a normal reaction of copper with sweat, especially in people with acidic skin pH. Skin staining may occur, this is a natural reaction of copper.

Sensitive people may experience irritation. In this case, it is better not to wear jewelry for a long time without interruption.

​​Service life of copper products with silver coating (electroplating).

 

Cleaning

and solving coating problems​
Сlean your jewelry at least once a month, and to wipe it when you remove it from your skin or clothing, especially before storing it in a jewelry box.

​

Silver plating may gradually wear off with frequent use; this is a natural process.

For light maintenance, simply wipe with a soft, dry cloth. For minor tarnishing, you can gently use a silver polishing cloth, avoiding excessive pressure.
Avoid abrasive pastes, brushes, and strong chemical cleaners, as they can wear off the silver plating.Do not soak the jewelry for a long time — a brief rinse in warm water with mild soap followed by thorough drying is sufficient.​

!
Water and sweat can accelerate tarnishing of the silver plating and oxidation of the copper.
Cosmetics, perfumes, lotions, hair sprays, and cleaning products can damage the silver plating.
It is recommended to put on jewelry after applying cosmetics.

​
 

Storage
Store pieces in a dry place, separate from other jewelry, to avoid scratches.
Use a soft pouch or case.
To slow down tarnishing, you can place anti-tarnish strips or acid-free paper with the jewelry.

*Instruction for the care of jewelry, which are created using accessories from Tierra Cast, are based on the official instructions of this manufacturer (some words may be replaced, but we tried to leave the meaning unchanged).

General information

Over time, jewelry can lose its shine. Regular wear, exposure to chemicals, cosmetics, and even air or water can cause this. The following guidelines will help you maintain the beauty of your pieces.

Not all metals tarnish at the same rate. Gold and rhodium-plated items remain largely untarnished under normal conditions. Brass and tin pieces are coated to slow down discoloration. Silver and copper items are more prone to tarnishing. TierraCast uses high-purity silver (11 and 12 fineness), giving it a warm, white tone. Like sterling silver, pure silver can tarnish with everyday use, especially when exposed to oxidizing agents such as water or sulfur-rich hot water. Copper items are made from pure copper and are naturally susceptible to tarnishing; antique finishes are applied to give them a distinct look.

 

​

What is tarnishing and how to prevent it?

Tarnish is a surface discoloration caused by the metal reacting with oxygen and sulfur compounds in the air. Sulfates may also be present in paper, plastics, leather, cleaning products, and cosmetics. Tarnishing forms a thin oxidized layer on the surface of the metal without affecting its core. On sterling silver, tarnish appears gray to light black, while pure silver may develop a slightly reddish tint.

Copper develops tarnish more quickly, so it is worth deciding whether to clean it frequently or only as needed.

Tips to prevent tarnishing of silver and copper jewelry:

1. Keep jewelry dry – Avoid wearing pieces in the shower or while washing dishes, as moisture accelerates tarnishing.

2. Avoid chemicals – Hair sprays, perfumes, lotions, and cleaning agents can affect the metal. Put on jewelry after applying cosmetics and cleaning your hands.

3. Store properly – Minimize exposure to air. Keep pieces in cases or special pouches. Anti-tarnish strips are available for additional protection.

4. Clean regularly – Remove tarnish early before it spreads. The longer it remains, the harder it is to restore the original shine.

Cleaning recommendations by metal type:
 

Gold (25, 26):

• Wash with a jewelry cleaning solution.

• Rinse in warm, soapy water.

• Gently wipe with a cotton pad dipped in acetone.

• Dry and polish with soft cloth or chamois.
