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.

Are the crystals of a mineral are always the same size?
No, they vary from crystal to crystal.
What causes minerals to form large and small crystals within the same rock?
Recrystallization. Recrystallization is a process whereby small crystals of one mineral will slowly convert to fewer, larger crystals of the same mineral, without melting of the rock.
What factor determine the size of crystals in metamorphic rocks?
Large mineral crystals that are all about the same size are formed from magma that cooled slowly inside the earth. Small mineral crystals (not identifiable without a microscope) formed from magma that cooled rapidly, on or near the surface of the earth.
How do two igneous rocks have the same mineral composition but different textures?
The texture of an igneous rock refers to the size of its mineral crystals. If the common magma of both igneous rocks has experienced differences in cooling rates due to depth, they will have different textures. Slow cooling produces large crystals, and quick cooling produces small crystals. Granite and rhyolite are two igneous rocks sharing the same mineral composition, but having undergone different rates of magma cooling due to depth at solidification.
What texture is igneous?
igneous is the texture of igneous rocks. The texture of igneous rocks is defined by 3 ways: a) Crystallinity- it expresses the degree of formation of crystals in an igneous rock. the texture of an igneous rock may be Holocyrstalline (Completely characterised by crystals, Hemicrystalline (partially having crystals) and holocrystalline (no crystals). b) Granularity- it is the size of the grains. it may be equigranular (when mineral grains are equal in size) or inequigranular (when mineral grains are not equal in size). c) shape of crystals- The shape of crystals may be Euhedral (When all crystals are of same shape), Subhedral (when they are partially similar in shape), Anhedral (when they are completely different in shape).

Is the cleavage for a mineral always the same for that mineral?
Yes, all different samples of that mineral will have the same cleavage.

Do the Swarovski pearls from the Bridal affordable jewelry set come from the same place as the Swarovski crystals?
Yes, the same company makes the pearls as the crystals.
Which is a factor that effects the size of mineral crystals formed in magma?
fluoresence is not a factor. I had this same question and i got fluorescence as a correct answer

Why is the color or a mineral not a reliabe physical characteristic?
The same mineral can come in a variety of colors and different minerals can be the same color.
Is true or false that the crystals in each mineral are the same shape?
Crystals of a certain mineral have a regular formation of atoms. However, crystals of the same mineral can grow differently. The presence of trace minerals, variations in heat, pressure, and the space that they have to grow in can influence the shape of a crystal. Crystalline structures demonstrate characteristic geographic variations for these reasons.

Which property will not always match a mineral's visible color?
The 'streak', or powdered mineral, will not always match the specimen's observed color.
