Without seeing the rock it is somewhat hard to tell but I suspect that, almost certainly, your rock is Specular Hematite. If it's rather heavy for it's size and the sparkle that you see looks like it's coming from zillions of individual specks on the surface, then it probably is Specular Hematite. Also, do the "sparklies" fall off if you rub the rock with your fingers? If they look like thin little flakes then it's certain the rock is Specular Hematite (also called Specularite).

Some minerals and other objects possess an interesting property called fluorescence. When you illuminate them with white light, they reflect some of it, just like any other object. This might cause a glow
You can buy neon spray paint at a craft store. If you want to make it glow in the dark, you can buy glow-in-the-dark paint, also at a craft store.
-minerals glow due to fluorescence from ultraviolet light.
The shine is either a reflection off the crystal faces of the minerals composing the rock, or a result of a rock with a glassy texture, like obsidian.
Because they have some thing in them that lets them glow

The minerals glow.
If you put them under ultra-violet light it changes color and glows.
fluorescent dyes is used to color-code during dna by changing the color
A phosphor become luminescent in some conditions (in fluorescent lights under electrical discharge); a phosphor is not the chemical element phosphorus.
Some minerals will glow in UV light; these minerals are called fluorescent minerals. Some minerals may continue to glow after the UV light is removed; these minerals are called phosphorescent.Click on the links below for further information and examples.
Some uranium salts are fluorescent, also many minerals. Biofluorescence is a known phenomenon.

Phosphors for fluorescent lights are one.

It is made up of 80% Iron, and 10% Nickel, and some other minerals.
Three minerals that glow under ultraviolet light are calcite, fluorite and sheelite. Sheelite gives a bright blue glow. Calcite can give various colors like red, green, pink and orange.
the minerals that make up a brick are cobalt, lithium, and nickel
Minerals because there are more minerals in rocks and crust. So that is the answer
Neon Fluorescent tubes contain argon.
