How to have the proper care for my permanent jewelry 

With proper care, your jewelry will last for years to come! Here are a few helpful tips to keep it looking beautiful.

Cleaning: Gold filled jewelry requires very low maintenance but please follow the M||M Jewelry Care Card you received with your purchase. It will still need some self-love every 30 days or so as it is going through life every day with you. Clean it with a polishing cloth OR soap, water and a gentle brush. 

Chemicals: While our jewelry is sweat, swim, and shower-proof, we do recommend avoiding prolonged exposure to hot tubs and spas especially with Sterling Silver as it can oxidize under those conditions.


What Materials Do You Use?

We strive to bring you the best quality chain and jewelry pieces made to last with the proper care. We want you to wear our pieces for years! That’s why we partner with the best, ethical suppliers and factories around the world, sourcing only the finest and best quality materials. 

Below, you will find important details about the materials we use.


Gold filled is a layer of gold pressure bonded to a base metal, typically a jewelers' brass.  It is becoming a very popular alternative to solid gold, because it's more durable, more affordable, and more versatile for different lifestyle and activities. Gold filled is different than gold-plated in several ways:

  • Gold filled contains a substantial layer of 14k gold, rather than a microscopic layer of gold plating (or gold dipped). Gold filled is required by law to have at least 5% or 1/20 of gold by weight. Consequently, gold filled is worth more and maintains its value better than gold plated, which has a minimal amount of gold.  

  • The process of pressure bonding makes the jewelry tarnish and chip resistant, unlike gold plating. This is why gold-filled jewelry is about double the price of gold-plated jewelry. A gold-filled finish will not flake off or chip and is tarnish resistant, if properly maintained and cleaned.


Sterling silver is a 92.5% pure silver with most likely copper as the remaining metal.  Sterling silver is considered a precious metal.  Here are a few more facts about the metal:

  • Although sterling silver is stronger than solid silver, it is softer than gold filled metal, and can be prone to scratching if not treated with care.

  • Sterling silver tarnishes naturally and occurs with even the most expensive sterling silver. Tarnishing with sterling silver is caused by a chemical reaction between the sterling silver and the air and any chemicals that come in contact with it. Your skin oils and body chemistry may actually help to preserve the sterling silver.

  • Although rare, some individual body chemistries can react with sterling silver and cause tarnishing. Pregnancy, thyroid disorders, hormone levels, medications and more can affect body alkalinity versus acidity, and may cause a reaction with your piece. It’s definitely a wild-card and is based on the individual.


  • Used to define the purity of gold in jewelry, 14k refers to the amount of pure gold in a particular piece. Due to gold being such a soft metal, it must often be mixed with an alloy to make it more durable. Furthermore, in addition to rhodium plating, 14k is blended with durable metals such as nickel, copper, and zinc. 14k gold is 58.5% gold and 41.5% alloy. 

Follow these suggested practices to ensure the long, beautiful life of your piece :

  • Keep jewelry protected when using chemicals: shampoos, harsh soaps, lotions, makeup, hairspray, etc.
  • Avoid abrasive materials like a terry cloth, bath towel, and shirt to polish your jewelry. We recommend using a soft cloth to gently clean your jewelry.
  • When cleaning your piece, start by using mild soap and water and gently clean the piece with your fingers. Make sure your piece is completely dried when finished cleaning to avoid oxidation.
