What We're Made Of

We founded Kosiner on the belief that making fine jewelry doesn’t have to come at the cost of our values, our communities, or our planet. We believe true sustainability is about transparently addressing both impacts on the environment and on the people in our ecosystem.For that reason, we strike a balance between recycled and fairly mined materials that support communities dependent on the industry

 

 




925 Sterling Silver

Sterling Silver has been used in fine jewelry since the 12th century, and we're keeping the tradition alive. We only use 100% recycled Sterling Silver made of 92.5% pure Silver to match the highest standards for all of our pieces.

Care

1.To minimize scratches and other damages, store your piece in the pouch that we procided or in a separate compartment in your jewelry box.
2.Remove your jewelry before exercising, washing your hands or showering. Always apply perfumes, creams and hair care products before wearing. To clean, polish gently with a silver cloth. Store in a safe, dry place when not worn.

 

 

 

 

 

 

 


 
14K Solid Gold

Solid gold is the least reactive metal and won’t oxidize or discolor. Our 14k gold has a subtle hue and is even more scratch resistant than 18k, making it perfect for everyday wear.
To ensure a positive impact on both the environment and local communities, we source a mix of recycled and artisanally mined gold. We work with recycled gold to reduce our environmental impact, and conduct due diligence to ensure that the gold is certified recycled.

Care

To maintain your gold’s rich luster and shine, all you need is a microfiber towel lightly dampened with water. Gently rub your piece on all sides, going slow to avoid scratches. Like most jewelry, 14K gold can be eroded and tarnished by harsh chemicals or repeated exposure to water, so we recommend removing any gold jewelry before getting into a pool or hot tub.
