The Decapolis (Greek: Δεκάπολις, Dekápolis, ‘Ten Cities’) was a group of ten Greek Hellenistic cities on the eastern frontier of the Greek and late Roman Empire in the Southern Levant in the first centuries BC and AD.

- Jasper (Wikipedia)
Jasper, an aggregate of microgranular quartz and/or cryptocrystalline chalcedony and other mineral phases, is an opaque, impure variety of silica, usually red, yellow, brown or green in color; and rarely blue. The common red color is due to iron(III) inclusions. Jasper breaks with a smooth surface and is used for ornamentation or as a gemstone. It can be highly polished and is used for items such as vases, seals, and snuff boxes. The specific gravity of jasper is typically 2.5 to 2.9. Jaspillite is a banded-iron-formation rock that often has distinctive bands of jasper.
