This item came in as part of a donation. We could not find any marking and have no idea of the age or stone or metal. I am sorry so we are pricing based on the beauty of the item. 100% of all proceeds from our POSHMARK sales go directly to support our Church's Youth Ministry out reach program . This special group of young adults share Christ’s message of hope and love to those less fortunate and in need. We sincerely thank you for looking and ask that you continue to check back as we will be listing donated items as quickly as we can. Reasonable offers are welcome. Bundle to save unless otherwise noted.
