Will my piece tarnished?

Gold-Fill:

Though gold-fill can naturally tarnish over time, it’s easily cleaned! We include a polish cloth in our packaging which we recommend using only when your piece is dull or tarnished—not for everyday cleaning purposes. It should be used “lightly” and not pressed hard against the metal to remove tarnish, as it could rub off the gold on your piece over time.

Rose Gold-Fill:

Rose gold fill is more prone to tarnishing than gold-fill because of the small amount of copper alloyed with the gold that gives it its beautiful pink color. but the same care tips that apply to gold fill also apply to rose gold-fill.  

To prevent rose gold and gold-fill tarnishing:

  • Avoid getting any product on your jewelry
  • Clean it with mild soap and warm water and thoroughly dry it after wearing
  • Store it in the storage we provided because it has added with extra felt protection to prevent oxidized.
  •  Avoid exposure to humidity  
What Metals Do You Offer?

The ability to choose your metal is (literally) the foundation of our jewelry. We offer four different metals to choose from; what metal is best for you and your piece is entirely up to you.

We only source metals that we are confident are authentic, high-quality and built to last, so you can’t go wrong with any option.

Sterling Silver

Sterling silver consists of 92.5% pure silver (hence why sterling silver is sometimes referred to as “925 silver”) and is considered a precious metal. The other 7.5% of the alloy is usually copper, which strengthens the silver without compromising its appearance.

Gold Vermeil

Gold Vermeil is a type of gold-finished material that composed of a thicker layer of 14-24k gold over solid Sterling Silver.

The thickness of the gold portion is usually 2.5 microns, and that's what set Gold Vermeil apart from simple gold plated pieces.

Surgical / Medical Stainless Steel

The anti-corrosive and hypoallergenic nature of surgical stainless steel is precisely what makes it so ideal for the medical industry; implants and other medical devices are made from this type of stainless steel, as it easily tolerates the body’s harsh environment.

Titanium Steel

Titanium Steel is a highly durable metal, allowing it to withstand the wear and tear of every activity. Stainless Steel itself will not rust, corrode, tarnish, stain, or change its color. Instead, it can last a little longer and look new if you often take good care of it.  

What does "Sterling Silver" means?

If you’ve spent some time shopping for jewelry, chances are you’ve seen the term “sterling silver” and wondered what makes a piece “sterling" silver rather than “regular” silver.

Silver is a softer metal; on its own, it is generally not ideal for long-lasting pieces of jewelry and other items. But way back in the 12th century (during some downtime between Bubonic plague outbreaks), someone figured out that an easy way to strengthen silver for practical use while preserving its ductility, malleability, and appearance was to mix it with another, stronger metal.

Sterling silver is considered a precious metal, and consists of 92.5% pure silver. (Which is why sterling silver is sometimes referred to as “925 silver.") The other 7.5% of the alloy is usually copper, which strengthens the silver without compromising its appearance.

It’s possible that your sterling silver could tarnish over time due to a natural chemical reaction that happens when it’s exposed to air. Luckily, sterling silver is a solid metal, so unlike gold-fill jewelry (which has a jeweler’s brass core), you can polish and clean it to your heart’s content and have it looking just as good as when you first got it without worrying about removing the outer layers of precious metal.

Note: When you receive your piece, you might notice that there’s not a “925” stamped on your jewelry - because most of our jewelry is handmade and doesn’t require a stamp of authenticity. But rest assured: We only use the highest quality, authentic sterling silver in our pieces.

Solid Gold vs. Gold-filled vs. Gold-plated

When it comes to deciding what type of gold you want for your piece, it really comes down to two main factors: how much you want to spend, and how long you want your piece to last.

Solid gold pieces will last virtually forever, but they are the most expensive option when it comes to gold jewelry. 

Gold-fill pieces are just a step down from solid gold. For many customers, they offer the ideal balance of price and quality.

Gold-plated pieces are typically the least expensive option, but offer lower quality. These pieces could easily chip or flake and there are few standards about what base metal can be used. In rare designs where we find gold-plated to be necessary, we only use quality Sterling Silver as the base metal. 

Can I wear your pieces if I have sensitive skin?

You’ve probably heard that gold jewelry can turn skin green or black after prolonged wear. Though very rare, this can occur even when using only high-quality materials.

This discoloration is not caused by the pieces themselves, but by a few common external factors—it can even happen with solid gold pieces.

Here are three common ways gold can discolor skin:

Metallic abrasion

This can occur when makeup or other cosmetics come in contact with your piece. Since gold is a soft metal, makeup can contain compounds that are harder than gold, causing super tiny particles to rub off over time. When this particle dust comes in contact with an absorbent surface (such as your skin), it can stick and form a black or green smudge.

Corrosion of metals

Even 14k solid gold contains other, non-gold alloys in it. Sweat and other natural oils from your body can cause corrosion of these non-gold metals, leaving a dark chemical compound behind which can stain your skin. This reaction can be worsened in semi-tropical locations and near the ocean where salt is in the air.

Chlorine

Chlorine from pools and hot tubs can eat away at gold and other metals to cause corrosion, leaving behind black or green smudges on the skin.

Here are a few helpful tips for avoiding discoloration of the skin:

  1. Always take off your jewelry before entering chlorinated water.
  2. When applying cosmetics, remove your jewelry beforehand and wash your hands thoroughly before putting them back on.
  3. Clean your pieces often If you want more information, this article also explains how external factors can cause skin discoloration in further detail.

JEWELRY CARE

How do I clean my jewelry and how often should I clean it?

Regardless of your lifestyle and how careful you are with your jewelry, it does need to be cleaned. With some simple daily maintenance and an occasional deep clean, your piece can retain its vibrancy.

Everyday Maintenance

After each wear, gently remove makeup and oils that can transfer from your skin to your jewelry by wiping it clean with a soft cloth. If you know you’ve been sweaty that day or think the piece might have product on it (especially sunscreen!), we highly recommend giving it a quick rinse in lukewarm water and then drying it with a soft cloth. Taking your jewelry off and storing it while you sleep will also increase its longevity, as it reduces exposure to air and natural skin oils.

Deep Cleaning

We recommend you to bring your jewelry to us for a deep cleaning every half a year to maintain for a longer time. You may refer to our Cleaning Services for setting your appointments and what are the things to prepare.

  • Store it in the storage we provided because it has added with extra felt protection to prevent oxidized.
  •  Avoid exposure to humidity  
How do I clean and care for my jewelry

Even if you are diligent about making sure your jewelry doesn’t get exposed to product or other harmful chemicals, your body’s natural oils can still cause tarnish over time.

We recommend giving it a thorough clean every dozen wears or so by soaking it in a bowl of warm water and mild dish soap for about a minute and then rubbing it with a cotton rag or soft-bristled brush.

Beyond that, we have a list of other handy tips for helping give your pieces good, long lives:

  1. After each wear, gently wipe and clean the jewelry piece with soft cloth to remove oils that can be transferred from your skin.
  2. When ready for putting on, try to put on your jewelry on the last to avoid contact with harsh chemicals like lotions, hairspray, perfumes etc.
  3. If you are going to any physical activities, gently take off your jewelry and put them in the pouch given by Cosibello.
  4. Be especially wary of sunscreen! It can cause severe, accelerated tarnishing on your pieces.
  5. Avoid leaving your jewelry dirty. If you’re not going to wear it for a while, make sure it’s clean and store them in the storage box or pouch.
  6. Take off your jewelry before you go to sleep—it will do a great deal to help it last longer! 
How Should I Store My Jewelry When I'm Not Wearing?

Knowing how to properly store your piece after each wear is one of the easiest ways to keep it looking great for longer, as it reduces the time it’s exposed to air, slows down oxidation and overall lessens the chance of tarnish. Below are some handy tips for storing your pieces.

  • Store it clean and dry after performing daily maintenance.
  • Use a small zip lock bag provided by us for storage. They’re inexpensive, can easily be made compact, help prevent tangling, and are airtight.
  • If your piece has a chain, make sure the clasp is closed before storing to keep your piece from getting tangled.
  • Keep your piece stored in a low-humidity environment to avoid tarnishing.
  • If your piece is more fragile, store the zip lock bag inside the pouch or box provided during travel. 

Please note that these tips apply mostly to gold-fill, rose gold-fill, and sterling silver. While it's still important to store solid gold safely, it's not susceptible to tarnish.

Can i Wear Them Everyday?

Even though our jewelry pieces are layered in 14k or 18k gold-filled, but we do not recommend customers in daily wear. 

You can potentially damage your jewelry by constantly wearing it, but there are no major health risks to wearing jewelry every day, which includes sleeping and showering.
