Very rare material.
FACET grade red/green/yellow color for this Lutetian or LowerBartonian (Eocene) amber, named Amekit. It has been found in the Ameki Formation near Umuahia, in southeastern Nigeria.
Very good transparency that allows lapidary work. HAlf polished.

Amber chunks occur within three successive sedimentary facies of this formation, and are generally associated with lignite and various marine organisms, suggesting they were washed into a marginal lagoon environment from a nearby mangrove-swamp area (Arua, 1979, 1986). Anangiosperm source has been suggested for Amekit based on the absence of gymnosperms among the fossil plants from the amber-bearing strata (Rao and Kumaran, 1988). But the molecular characterization of the amber by infrared spectroscopy and gaschromatography-mass spectrometry (Py- and THMGC-MS) indicates a Class Ib amber typicalofconifers, possibly the family Cupressaceae (Sonibare et al., 2012).
