There are many stones that glints, but here are a few possibilities depending on what kind of glint you're thinking of:

For a bright, reflective glint:

* Diamonds: These are the classic "glinty" stone, known for their exceptional brilliance and fire.

* Quartz: Many varieties of quartz, like rock crystal, smoky quartz, and amethyst, can reflect light in a bright, sparkling way.

* Glass: Though not a natural stone, broken glass can glisten and sparkle just like a gemstone.

For a more subtle, muted glint:

* Feldspar: Certain feldspar varieties, like moonstone and labradorite, can show a shimmery, opalescent glint in the light.

* Mica: Mica flakes have a reflective surface and often give a subtle, silvery glimmer.

* Metallic ores: Ores like pyrite and galena have a metallic luster and can reflect light in a dull, glittery way.
