Vintage Zuni Style Inlayed Butterfly Pendant 0.75"

Vintage Zuni Style Inlayed Butterfly Pendant 0.75" Measures about 0.75" not including bail. I am unsure of the materials but inlay at bottom looks like it could be mother of pearl, though a tan shade Some color variation to bottom inlay with one being darker than the other. No chain included. Light marks to the front. Silver has no stamp so not sure if sterling silver or just silver tone but the it does have some marks/blemishes and requires a good polish. Preowned necklace sold as shown - I am unsure of material type(s) because of this. Pictures show different angles for you to review - while I attempt to note any defects, some tarnish/signs of wear may be visible that are not otherwise stated. I ship quickly but delivery times are an estimate and will vary due to how the mail service is these days. Tracking information will be provided. Item is located in the United States. Country of manufacture cannot determined.
