The mineral with glassy luster, and milky white is Quartz
Quartz
A milky white mineral made up of silica is quartz. Quartz is the second most abundant mineral on the Earth's crust.
Milky quartz is a relatively common mineral found in the earth's crust. It has little intrinsic value. It is, however, one medium in which gold is found.
I think Calcite. Calcite is 3 on the hardness scale and sometimes you can break it into cubes. The difference between Calcite and Quartz is that Calcite is a milky white.
Milky quartz is caused when fluids are trapped in the crystal early in its formation. Milky quarts is considered a flaw of the quartz by some.

That is pearl brilliance; the shine and glow of a pearl. The greater and deeper the luster is, the more valuable the pearl. Peals with a high luster display strong and sharp light reflections and a good contrast between the bright and darker areas of the pearl. Pearls with low luster look milky, chalky and dull.

BaSO4 is a type of mineral known as Barite which is made from barium sulfate. It comes in many colors but it is commonly milky white or has no color at all.

milky quartz is either metamorphic or igneous

Peals with a high luster display strong and sharp light reflections and a good contrast between the bright and darker areas of the pearl. Pearls with low luster look milky, chalky and dull. Pearl Luster is the factor that provides the pearl with its true beauty - it's that mysterious inner glow that seems to emanate from the center of a genuinely high-quality pearl. Usually, a pearl's luster is a combination of surface reflection and a glow that really does come from within - from the many layers of nacre built up over time inside an oyster.

Quartz is a naturally occurring silicate mineral composed of silicon dioxide (SiO2). Its hardness is 7 on the Mohs scale and it is in the trigonal crystal system. Quartz possesses a glassy luster and does not exhibit cleavage. The average specific gravity of quartz is 2.62. Quartz can be found in all three rock types, igneous, metamorphic, and sedimentary. Quartz has a white streak, but specimens can be appear colored by impurities or exposure to heat or radiation to hues of white, pink, red, orange, yellow, blue, green, black, smokey, milky, or purple.Quartz is a mineral, chemical composition of silicon dioxide, one of the most common minerals on the planet.
