American Neptunite 0.290ct Loose Stone with Certificate of Authenticity

Neptunite is a rare mineral named after Neptune, the Roman god of the sea, and was discovered in San Benito, California, along with blue benitoite. It once attracted attention for its symbiosis with benitoite, but now that production of benitoite is declining, neptunite from San Benito, USA, is also becoming rare.

This is Neptunite that just arrived from Tucson, USA.
Neptunite is extremely difficult to polish due to its cleavage and tendency to break, and not many are sold as loose stones. This is a high-quality neptunite with excellent transparency and crystal condition, making it perfect for enjoying as a loose stone. It comes with a certificate of authenticity from an AGL-affiliated appraisal agency.
