Because they can take long to form resulting in a large crystal well-formed. And also remeber fast forming Crystal =small, slow forming Crystal =large

Geodes form spectacular euhedral crystals because of what reason?
The crystals have abundant room to grow in their hollow surroundings also the crystals can form very easily in many places.
Are geodes filled with anhedral crystals on its walls?
no
Rock called geodes are filled with layers of crystals What is the complete predicate?
nut
Why do the crystals inside geodes vary in color?
Crystals inside geodes will vary in color for a number of reasons. The solutions inside a vug may consist of varying concentrations of different mineral solutions. The mineral crystals that form from these solutions may have a specific color associated with them, such as malachite (green), azurite (blue) or rhodoschrosite (pinkish-red). Minerals that normally have a clear crystalline structure may appear clear or be colored by small amounts of impurities such as iron. In other cases, the minerals inside a vug may be exposed to varying amounts of radiation which can affect their color.
What are thunder eggs?
Thunder Eggs are rocks containing crystals inside them. This is what makes them geodes.

How much is a geode worth that has water inside?
== == It depends on what's inside. Large amethyst geodes can go for thousands. Baseball sized geodes with non-spectacular quartz or calcite crystals can be purchased for $4-$12. Geodes with uncommon minerals that are sold on mineral auction sites range in price from $30-$500. Golf ball sized geodes, uncracked, are sold for about $2 at shows.
Are geodes filled with anhedral crystals on its walls?
no
Could you tell me stuff about the rock Geode?
Geodes are rock cavities with internal crystal formations, usually made of quartz crystals. Some geodes are completely solid because they are filled with crystals. These are called "nodules". Geodes can form in gas bubbles in igneous rock, or in rounded cavities in sedimentary rock. Most geodes contain clear or white quartz crystals, but purple amethyst crystals are also common.
What is another name for mineral crystals in cooling magma or lava?
Geodes
What are some basic facts about geodes?
Geodes are secondary structures that occur in sedimentary and igneous rocks. Geodes are hallow on the insde. They are spherical to oblate in shape. Most contain clear crystals, though some may contain colored crystals. Geodes are common in the U.S. states of Indiana, Iowa, Missouri, Kentucky and Utah, and the countries Mexico, Brazil, and Namibia.
What type of rock is lined with quartz crystals?
Geodes are often lined with quartz.

What minerals are in geode?
A number of different minerals can be found within geodes, but they are mostly composed of quartz.

Can you find quartz crystals in Illinois?
the only place i have found them in illiinois is inside of geodes.
