Jewelry Care & Repair

Fleur Kassels Fine Jewelry


We believe jewelry is meant to be worn every day. Most of the jewelry we sell requires very little care — just wear and enjoy.  We do recommend taking off your jewelry when swimming, gardening, doing contact sports, seriously messy cooking, and moving heavy objects. That said - it depends on your lifestyle, your aesthetic preferences, how often you lose things (taking jewelry off regularly seems to be the biggest culprit in loss!).

With that in mind, here are some helpful tips to keep your jewelry looking its very best!


If a piece needs repair work, please sent it to the following address:
Be aware, the return address is different from the atelier address.

Make sure to put your contact details in the package and to pack the jewels really well so nothing gets lost in the mail.

Do not ship jewels in a paper envelope, it breaks easy and your jewels will fall out.

Repair work will be done for minimum costs, starting from 10,00 euro (including packaging and sending) depending on the type of damage. If the damage is due to a productional error, the repair work is free of charge.

Please note repairs on the envelope, your email address & post address.
Repairs will take 2 to 4 weeks.


Despite being rather sensitive beauties, pearls love being worn!! They don't like being stored away and their intrinsic luster and glow will only improve when worn regularly. 

However, they do need proper care to last many many lifetimes. Pearl experts say: put them on last and take them off first. Pearls are more vulnerable to the chemicals found in cosmetics, hair spray, hair dye, and perfume. And pearls do NOT like chlorine - neither in swimming pools or even regular showers. Do all your primping before you put your pearls on. 

Pearls should ONLY be cleaned with a soft cloth moistened with water and the little bit of ivory soap. 



Mix a small amount of mild dish detergent with warm water in a bowl. Put the jewelry into the bowl and let sit for a few minutes. Use a soft toothbrush (like a baby tooth brush) to gently scrub the jewelry. Remove item from soapy water, rinse it and dry thoroughly with a soft polishing cloth. 



Silver tarnishes quite quickly when it comes into contact with oxygen or sulfur. Happily, the best measure to prevent this is wearing your silver jewelry often. The oils in your skin help prevent tarnish. (This varies depending on your own body chemistry.)

When storing your silver jewelry, use an airtight plastic bag (like a Ziploc) and if you can, put in a piece of chalk or a silica gel (the little packets in new shoes) - these will help prevent tarnish while you are not wearing your silver. If your silver is tarnished the best way to clean it is with a jewelry polishing cloth. 

There are also many viable home remedies for cleaning silver online. Just remember that silver is very soft so use something like a very soft baby toothbrush to avoid scratching.
