Ruby is a variety of the mineral corundum, and is not classified as sedimentary, igneous, or metamorphic in the manner of rocks.
It is neither. Ruby is a mineral that is created in metamorphic environments.
Burial of sediment does not make igneous rock.
Igneous rock can become sedimentary if it is weathered into sediment and then lithified.
igneous rock
Sedimentary rocks can change to igneous rock when it goes through the rock cycle so a sediment can move to igneous rock where there is a volcanic activity happens making the the sediment get heat and pressure that makes igneous rock.So when you do the rock cycle you can go from igneous rock to a metamorphic rock.

igneous rock
The igneous rock gets weathered into sediment by wind, water, and ices. The sediment is deposited in a basin and buried. The pressure of burial and the heat inside Earth turns that sediment into stone.
When igneous rocks are crushed and compacted into sediment

Erosion
It will be in a volcanic or sediment rock.
Sedimentary rock melts, then it cools to form Igneous rock. Hoped this helped. :)
The igneous rock must be broken down into fragments called sediment and somehow cemented together.
