the mineral cooled very slowly underground
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.
The small crystals likely formed due to rapid cooling of the molten rock or solution from which the mineral precipitated. This rapid cooling did not allow enough time for the crystals to grow larger, resulting in the formation of small crystals.
Yes, naphthalene crystals are soluble in mineral oil, as both are nonpolar substances. When naphthalene is added to mineral oil, it dissolves to form a homogeneous solution.
It is a silicate mineral ex: crystals
There are many mineral crystals that have value. Some examples would be diamonds, rubies, amethyst, and sapphires. All are formed deep in the earth.

The mineral cooled rapidly on earth's surface
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 most probable explanation is the specific structure of grouped crystals - a lamellar type.
Dresserite is a micro-mineral that does not contain any particularly valuable element. It is used only as a mineral specimen for hobbyists. It is not colorful; neither are the crystals large. Many mineral collectors would not give it a second (or even a first) glance. Micromounters (who view small pieces through microscopes) are among the very few who appreciate these tiny crystals.
What mineral that appears in transparent hexagonal crystals
Correct, a 5 hardness can scratch a 5 and below.
The value of samaraskite as a mineral specimen can vary depending on factors such as size, quality, and rarity. Generally, samaraskite is considered a rare mineral and specimens with well-formed crystals or attractive coloration may command higher prices among collectors and mineral enthusiasts. It is recommended to consult with a mineral expert or appraiser for a more accurate valuation.
Mineral specimens with very large crystals most likely formed in environments with slow cooling rates and sufficient space for crystal growth, such as pegmatites or hydrothermal veins. These conditions allow for the growth of larger crystals due to reduced competition for space and slower precipitation rates.
The arrangement of atoms in a mineral sample can cause the formation of crystals.
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.
