This pagoda-like aggregate of SHARP, maroon-red spinel crystals measures about an inch across, and crowns a well-excavated matrix of starkly contrasting white marble. This is classic Vietnam spinel from a find I bought during the heyday here, about 2005. The luster is waxy and bright, unusual for such deeply colored spinel from here (usually only the lighter red hues have such luster, it seemed) .
