How these sparkling sugary crystals come about is a mystery to many. So I will try to explain as simply as i can.
Remember this ?(this is the only chart, I promise)
The constant moving of the earth’s crust and inner layers is responsible for the forming of most of the colored gemstones we see today. Many millions of years ago, as molten rock was being forced up to the surface, heat and pressure changes caused gases to expand and create cavities within the solidifying rock. Gazzillions of years later, as the ground water, rich with minerals, (i.e. dissolved silica) moved through the rock, it deposited new minerals into the cavities, (or on the surfaces) of the rock, and cooling began to occur. Crystallization of these minerals on top of and inside the previously crystallized rock began the unique crystal formation called Druzy. Druzy colors are based on the particular stone that the mineral water leaked into all those years ago.
In the following photo you can see some of the filled cavities and you can see the tightly-packed matrix which creates a dense bed of individual crystals. Notice how each each crystal only has a single termination pyramid exposed. This bed of crystals has a very fine crystalline structure similar to sugar or salt crystals. This is an "encrustation" crystal habit, or Druzy. This is why it is so sparkly. That pyramid catches light from every which way.
