This necklace is made with copper. This pendant hangs on an 18" gunmetal chain necklace. See all photos before purchasing. Quarter for scale. If you would like to request a different necklace length, please email me at ashley@copperashes.com with your order number and request. Disclaimer: Colors may vary slightly from photos due to lighting. All copper is sealed with a protective coating to keep the metal color preserved. The coating eventually will wear off and metal colors may change. To prevent metal changing, you can apply coatings of clear nail polish as needed. It is also NOT recommended that you wear this jewelry in water.
