Jewelry Care

Every piece of Jco jewelry is hand-crafted and made from sterling silver, requires delicate handling.

It is completely natural for sterling silver to oxidise over time when it’s exposed to air. After each wear, use a jewelry cleaning cloth to give the piece a gentle wipe and it will shine right back up! You may also use this cloth to lightly polish your yellow & rose gold plated pieces, if needed.

All jewelry should be taken off before showering/swimming/exercising, and kept clean & dry in a closed storage, such as an air-tight plastic bag provided, when not in use. Jewelry should be properly cleaned from time to time to maintain the product.


Our endless hoops need a special, but easy, instruction on how to close them. When we make the hoops we finish them with the pin quite tight into the tube of the hoop; this is for quality reasons. When you open them to put them into your ears they, therefore, sometimes don’t close directly. The key on how to close them is to bend the pin just a little bit with your fingers until the pin slips pretty easily into the tube of the hoop. Next, put them in your ears and you’ll notice that they close surprisingly fast.


We strive to use the finest quality materials to craft each piece so that your J&Co Jewelry purchases can be treasured forever. 14k gold filled, 14k gold vermeil & sterling silver are the primary materials in the J&Co Jewelry collection. 

All of our earring posts are made of hypoallergenic sterling silver. We use genuine semi-precious stones and Swarovski crystals.

What is 14k Gold Filled?

Gold filled components contain 100+ times more real gold than gold plated components and are very durable and tarnish resistant. Gold filled jewelry is a beautiful, affordable alternative to solid gold, and can be worn by people with sensitive skin.
