Every piece from OSS is carefuly handcrafted in our studio in Paris. Following are instruction on how to make your jewellery last a lifetime: 

Always protect your jewellery from sharp blows, scratching, chemicals, sunlight and heat/cold.

When you store your jewellery, try to keep pieces apart so they don't rub together.

Never go swimming wearing your jewellery, as chlorine in swimming pools can cause damage to all metals and will completely remove the oxidation from your piece.

Avoid wearing while cleaning, gardening or performing sports activities.

Your jewellery will age and black color from oxidation might change its color or even disappear. However, if you take correct care of your piece you can make color last longer. 

If you own a total black jewellery, with the use oxidation will probably start to lose it`s  intenisity, or slowly dissapear. 

If this happens to you and you want your piece to be all black again don`t hesitate to contact us, and we`ll be happy to help you. You can send us your piece back and we`ll do a re-oxidation, or we can even give you instructions so you can oxidize you jewellery at home!
