Gabbro
Gabbro is a type of dark, coarse-grained rock found deep within the Earth's crust. It is often used in construction and as a decorative stone due to its durability and attractive appearance.
Appearance
The Gabbro has a dark, often greenish-black or gray appearance with visible coarse grains. Its specks of plagioclase feldspar can sometimes flash with an iridescent blue or green sheen, making it distinct from finer-grained dark rocks.
