This Phosgenite is a short prismatic complete crystal with a flat termination. The prism faces are mildly striated and the color is a light brown to colorless white. The luster is good. No damage. Mounted on acrylic. 

Monteponi is the premier world locality as Pagano points out in his MR (v45 Nov/Dec) article. There is no other locality which exhibits the color, luster and crystal size like Sardinian Phosgenite. Yellow-orange fluorescence under longwave UV (as shown).
