Large Vintage Native American sterling onyx hand stamped necklace

Large Vintage Native American sterling onyx hand stamped necklace, measurements in pics, solid silver unmarked. The center pendant can be removed for that one day out of the month that you just don't want to be totally over the top. No issues, necklace 20" long. Marked or unmarked as shown in pics, weight and other measurements in pics. Sorry but my jewelry is stored in a secure location and cannot be accessed for more pictures, videos, or measurements until sold. If you look at pictures/description your question should be answered. Thank you so much for your time and consideration! All precious metals are tested and guaranteed. A Native American jewelry piece referred to as "silver" or "ingot" is guaranteed to be at least 90% silver. Bracelets are photographed on a 6" women's wrist.
