FootnotesComprising 0.2% of all meteorites, pallasites are the rarest and most aesthetic examples and are highly sought after by collectors and museums. This cross-section reveals their mesmerising internal structure, consisting of translucent amber-coloured olivine crystals suspended in a shimmering iron-nickel matrix which has been polished to a mirror finish. Of all known pallasites, Sericho is especially renowned for its high concentration of olivine, often displaying hues of orange, yellow and green when spotlit or in direct sunlight. Cross-sections of this scale and integrity are particularly rare. While prized for their beauty, Sericho meteorites are also notoriously prone to oxidation if not treated correctly. This piece has been carefully prepared, resulting in a stable specimen that retains both its visual clarity and structural integrity.

From a UK collection formed in the 1980s. Property of an Essex, UK, gentleman.
The mammoth lineage branched from the Asian elephant around 6 million years ago, and later on the Woolly Mammoth, Mammuthus primigenius, evolved in eastern Siberia. Woolly mammoths, being slightly smaller than living African elephants, were foragers and ate grass, as well as small, nutritious flowering plants that flourished in the environment where they lived. They may also have used their curved tusks to dig through snow and eat plants that other foragers were unable to reach. -
