Natural Brazilian Agate Drusy Crystal Egg Rock
This Brazilian Agate Druse egg is almost 2.5 inches or 60 mm in height.
This is an all natural deep, luminous, gray Agate from Brazil with a natural crystal vug.
The crystals are also gray with brown tinge and black dots, and sparkly!
Many agates are hollow, since deposition has not proceeded far enough to fill the cavity, and in such cases the last deposit commonly consists of quartz crystals directed towards the free space so as to form a crystal-lined cavity, or geode.
A layer of very fine crystals is known as "Drusy or Druse". Often the Druse will be the color of the mineral underneath.
