The context of your question is unclear. Virtually any stone broken into gravel-sized pieces will feel like gravel.
Peridotite is mainly composed of olivine, along with pyroxenes and minor amounts of other minerals like spinel and garnet. These minerals give peridotite its characteristic green color.

A conglomerate rock is composed of many different sizes of pebbles, gravel and sands. Exactly like concrete is.
Peridotite rock comes from the Earth's mantle, specifically the upper part of the mantle known as the upper mantle. It is formed from the cooling and solidification of magnesium- and iron-rich magma beneath the Earth's surface. Peridotite is typically brought to the surface through processes like mantle upwelling or tectonic movement.
Peridotite is a dense, coarse-grained igneous rock.
The igneous rock peridotite has a very high color index. It is comprised of more than 95% mafic minerals (like olivine), giving it a dark green color.

Olivine is the mineral that is present in much greater quantities in peridotite compared to gabbro. Peridotite is rich in olivine, which gives it its characteristic green color, while gabbro contains less olivine and more dark minerals like pyroxene.
Gravel typically feels rough and coarse due to its irregular shapes and sharp edges. Walking on gravel can provide a crunchy and unstable sensation underfoot.
