view of stone 875

Corsi 875, approx. 145 x 73 x 40 mm, © Oxford University Museum of Natural History

OUMNH Number: 875  
Name and quarry location: Granito delle Alpi, from the Alps; or perhaps breccia d'Armenia, from the historical region of Armenia  
Geological description: Coarse hornblende quartz monzonite with pale green-stained (chloritic?) plagioclase and accessory apatite. Specimen shows faint foliation.  
Comments: Perhaps from the Alps, but it is remarkably similar to breccia d'Armenia among the ‘ancient’ marbles of the Bullucci brothers acquired in 1889 by the Naturhistorisches Museum Wien, suggesting the historical region of Armenia (the modern country of Armenia and parts of modern Iran and Turkey) may be the provenance. Brown areas are polishing compound, and the specimen has fairly well colour-matched green wax filler in places along the edges.  
References: Other examples: T1-7-1 F2303 'Breccia d'Armenia Antica Rarissima'.
