Labradorite is one of my favorite materials to work with! Each piece has such a unique flash. This one has hints of orange, blue, purple, and teal. Please see the last photo; it is rare to find a piece of labradorite that "flashes" from every angle, and so I have provided a photo of it when it does not flash. This is a beautiful stone. Every copper pendant comes with a standard 18 inch copper chain with a lobster claw clasp. It should not tarnish on your neck; I purchase jeweler grade chain. If you would like a leather cord instead, there is no upcharge! Just add a message on your order, or submit a message through my contact page. If you want the chain/cord longer or shorter, there is no charge for that either. Just let me know! If no message is sent, your pendant will be shipped with an 18 inch chain, as is standard.
