Lapis Lazuli is an incredible material that has been traded since the days of the ancients. It can be found throughout the world but most comes from Russia and Afghanistan. The mines in the Sar-i-Sang region of Afghanistan have been operating for perhaps a millennia where they dig into a metamorphic layer that was once limestone. Lazurite gives it the blue, calcite imparts the white banding and pyrite (fools gold) gives it that spark.
The stones are 26mm wide and hang 38mm on hammered 14k gold wire.
