Recycled Stones

A recycled stone is a naturally occurring stone, cut and polished from mined rough, previously set in jewelry then removed, and re-introduced into the supply chain for resale. Many of our pieces containing recycled stones are exclusively available on our website and are made in extremely limited quantities. Because of the scarcity of certain types of recycled stones we cannot guarantee that we will be able to reproduce certain styles.  


When using diamonds, Winden chooses recycled stones whenever possible. Approximately 4.5 billion carats of diamonds have been extracted from the ground since large scale mining efforts began in South Africa in the 1870’s. This means many millions of diamonds are part of the world’s existing, above ground, supply of diamonds. In order to reduce the industry’s reliance on environmentally damaging mining practices, Winden is proud to participate in the reintroduction of a small portion of these many millions of diamonds back into jewelry. Select Winden pieces use diamonds that are not recycled but that are Kimberley compliant. The type of diamond used for each piece is indicated in our product descriptions.

The following gemstones used in Winden jewelry have complete traceability from mine to market.

Idaho Garnet

The garnet used in Winden jewelry is mined in Idaho and cut and polished in a Fair Trade Gem facility in China.

Oregon Sunstone

Winden uses sunstones that are 100% natural, they are not enhanced in any manner with chemicals, diffusion, heat or oiling. They are cut and polished in India, in a Fair Trade Gems facility in China and on-site by local artisans. Sunstone comes in shades varying from deep red to vibrant green. Each Winden sunstone is hand-selected for its beautiful color chosen to complement every skin tone.

Montana Sapphires

Some Montana Sapphires used in Winden jewelry are heat treated to bring out the naturally occurring color in the stone. The heated sapphires we use are treated in the USA and are subjected to heating alone, with no coloring agents, fluxes, or glasses added during the process. They are then cut and polished in a Fair Trade Gem facility in China. Each sapphire is selected by hand to find the most beautiful shades of pale blue and green.

Australian Sapphires

The Australian Sapphires used in Winden jewelry are mined in Central Queensland where the state government regulates all aspects of the mining process, including consultation with traditional landholders. These sapphires are unheated and are cut and polished in Thailand or in a Fair Trade Gem facility in China. Each stone is hand-selected for its vibrant shades of yellow, green, and blue and its indisputable uniqueness.

Oregon Agate and Jasper

The Snowflake Agate, Black Jasper, Saturn Jasper, and Owyhee Sunset Jasper used in Winden jewelry are mined in Oregon and cut and polished in a Fair Trade Gem facility in China.

Found Stones

In an effort to create a more sustainable product, found stones were incorporated into Winden designs as early as 2017. The stones are found by the designer in various places from Lake Erie to the Mediterranean Sea. Found stones referred to as pebbles in Winden pieces are polished and sometimes drilled however, they retain their natural shape. Other found stones are cut and polished into a specific size and shape. All cutting and polishing of found stones occur in New York.
