Under ground took a lone time to cool all I can tell you
Large crystals in a mineral specimen typically form under conditions that allow for slow cooling or low rates of crystallization, allowing more time for the crystals to grow. This can happen in environments such as deep underground or in cavities where there is minimal disturbance to the crystal growth process. Large crystals are often prized by collectors for their unique beauty and rarity.
The crystals will always form according the geometric parameters of the mineral crystal system to which they belong, but the size of the crystals varies depending on the environment in which they form.
Crystal form refers to the specific geometric shape in which a mineral naturally grows. It is determined by the internal atomic arrangement of the mineral. Crystals can exhibit various forms such as cubes, pyramids, and prisms.

No, melted rock that cools quickly result in igneous rock with large minerals because large crystals take time to form and the rocks that usually have them are the ones that were formed inside the earth.
Large crystals in a mineral specimen typically form when the mineral has enough time and space to grow without being obstructed by nearby crystals. This often occurs in environments with slow cooling rates or low levels of impurities, allowing the crystals to grow to a considerable size.

No, a rock with visible layers and no mineral crystals likely did not form from lava hardening on Earth's surface. Such layered rocks are typically sedimentary, formed from the accumulation and compaction of sediments over time. In contrast, igneous rocks formed from lava cooling often contain visible mineral crystals, as the cooling process allows crystals to grow.
All rock does not contain mineral crystals. Obsidian, or volcanic glass, in particular is a rock that has cooled so quickly from lava that mineral crystals were not able to form.
Pyrite is a mineral that can form crystals.
Magma beneath the Earth's surface cools and solidifies to form mineral crystals. This process takes place over long periods of time, allowing different types of crystals to form depending on the minerals present in the magma.
Salt and ice are two common mineral crystals.
A supersaturated solution is most likely to form crystals as it cools.
The mineral is likely calcite, which exhibits birefringence, causing light to split and create double images when passing through the crystal. This property is known as double refraction and is a distinctive feature of calcite crystals.
