Yes crystals do grow under the ground.
Underground crystals are bigger where as crystals formed on the surface are smaller.
to make crystals grow
Igneous rocks with large crystals are known as intrusive or plutonic rocks. These rocks form underground as magma cools slowly, allowing large crystals to grow. Common examples include granite and diorite.
Usually from the slow cooling of magma with a plentiful supply of material necessary for crystal growth, and space in which to grow.
Because as an intrusive rock cools underground, it will normally cool more slowly than an extrusive (surface) rock. The slow cooling allows more time for the crystals to grow.

crystals best grow in warm temperatures.
Alum crystals and sugar crystals grow at the same rate at an increasing time rate making them grow the fastest
Gabbro cooled slowly underground, resulting in the formation of coarse-grained crystals in the rock. This slow cooling process allows large crystals to grow and develop in the molten rock.
In rocks or in underground caves
An igneous rock's crystal size is dependent on how long it takes to cool from magma into a solid. Intrusive igneous rocks, the ones that solidify from magma underground, are slow to harden, giving crystals plenty of time to grow larger. Extrusive igneous rocks, formed from lava above ground, cool fairly rapidly, not allowing the crystals much time to grow in size.
