From the album: Fossil Amber and Copal: Worldwide Localities
A small run of amber from the West Open Pit Mine in Fushun, China, weighing .7g and measuring (mm) 11x15x9; the oblique view better displays the slightly oxidized surface of the largest flow in the piece. The mine was closed in 2019, but small pieces of amber are still recovered from coal found in the gangue piles; it is separated from the matrix by mechanical action and immersion in large vats of saltwater solution, and recovered with netting as it collects at the surface. This material is hard, takes a high polish, and is often shaped and drilled to make beads. Its chemical and spectrographi© Kaegen Lau

A small run of amber from the West Open Pit Mine in Fushun, China, weighing .7g and measuring (mm) 11x15x9; note the several flow lines of successive runs. The mine was closed in 2019, but small pieces of amber are still recovered from coal found in the gangue piles; it is separated from the matrix by mechanical action and immersion in large vats of saltwater solution, and recovered with netting as it collects at the surface.

Small run of amber from the La Cumbre Mine, weighing 2.4g, and measuring (mm) 37x13x8. It consists of numerous successive flows, and contains several small single-phase bubbles; as this specimen does, several others I have (from the same 2kg lot) from this locality also display an interesting "schiller" effect when adjusted in-hand (light reflects off of the flow lines' surface). Biological inclusions are a possibility with this specimen, though I will need to prepare it to confirm this.© Kaegen Lau
