A speleothem is commonly known as a cave formation or decoration and is a secondary mineral deposit formed in a cave.
Speleothems are typically formed in limestone or dolostone solutional caves.  The word speleothem (from the Greek for "cave
deposit") is derived from the Greek words
spelaion meaning "cave" and thema meaning "deposit".

The speleothems with which most people are familiar are stalactites and stalagmites. Stalactites grow down from the cave
ceiling, while stalagmites grow up from the cave floor. It’s easy to remember which is which: Stalactites have a "T" for top and
stalagmites have an "m" for mound, (or “G” for ground).

Speleothems actually form because of water. Rainwater seeps through cracks in the rock. As it passes through organic
material, it picks up carbon dioxide gas, creating carbonic acid. This weak acid passes through joints and cracks in limestone.
The mineral calcite is dissolved from the limestone rock in which a cave is formed. When this water that now holds the dissolved
rock is exposed to the air in the cave, it releases the carbon dioxide gas, much like when a bottle of soda is opened. As the
carbon dioxide is released, calcite is precipitated (redeposited) on cave walls, ceilings and floors. As the redeposited minerals
build up after countless water drops, a stalactite is formed. If the water that drops to the floor of the cave still has some
dissolved calcite in it, it can deposit more dissolved calcite there, forming a stalagmite.

Speleothems form at varying rates as calcite crystals build up. Several factors can determine the rate of growth. Two important
factors are the temperature outside (which affects the rate of decay of plants and animals, hence the amount of carbon dioxide
in the soil), and the amount of rainfall. The shapes of speleothems are determined by how the acidic water enters the cave (by
dripping, seeping, or splashing) and how the water stands or flows after entering the cave.

Most scientists believe that the color of speleothems are determined by the mineral content. Pure calcite is white and almost
colorless. Iron and other minerals, as well as acids from surface vegetation, combine with calcite crystals to add shades of red,
orange and black to the color of speleothems. Others believe that humic and fulvic acids in the soil may also contribute to
speleothem coloration.
This Stalactite was obtained legally and was found in the Ozark Mountains on privately owned land.
This speleothem was harvested post-growing only  with minimal disturbance to the ecosystem around it.
We do not endorse or encourage removing growing speleothems  from live caves!
This is a magnificant and extremely rare stalactite speleothem formation as shown in pictures, in different lighting
conditions. This specimen stands 8" tall. Multi-colored and stands upright on it's natural base! This specimen has
beautiful color without being thoroughly cleaned (only soaked). This piece would make an excellent home decor
addition or a Science and Geology study specimen.

It is a museum grade stone artifact grown from the water dripping on the cave floor and depositing it's minerals to
form this fantastic natural wonder. Specimen was collected in the Ozark Highlands region of Missouri. A valuable
addition to any collection.
This formation was legally harvested, post-growing, out of a privately owned cave. This formation is guaranteed to be
from a private cave and gathered from the cave floor. These are very rare, special and ancient minerals.

This specimen weighs 2.43 lbs (1.1kg) and measures 8 x 4.3 x 2.7 inches (20 x 10.8 x 6.8cm)

Group of 5 Stalactite
Kokoweef Cave Onyx
Speleothems from
California

$60.00
California Cave Onyx

These 5 specimens were legally removed from a
private claim at Kokoweef Cavern in the Ivanpah
Mountains in San Bernadino County, California
about 28 years ago, collecting is no longer allowed.

Kokoweef Cave Onyx yields fantastic patterns when
cut, polishes nicely, or makes nice display pieces.
Together they weigh 1.30 lbs., and are up to
approx. 4" x 2" x 1.1". You get all 5 pieces.
The top of the specimen to
the right has been ground
down a little and a rough
wheel polish to look at the
material from a lapidary
viewpoint (see above)
This is a cabachon made from
Kokoweef Cave Onyx by
bitterbrookcabachons
Cave Onyx is a calcium carbonate accretion from these
caverns. Legend has it that in the 1920s, a man discovered an
underground river full of golden nuggets in these limestone
caverns. These were collected at Kokoweef Caverns,
California in the 1970s. This area is no longer open to
collectors. The current owners are in the process of searching
for the legendary under ground gold laden river. These would
make a great addition to your mineral collection!

Aragonite Stalactite  
Speleothems from Mexico

$42.00
Aragonite Stalactite Cluster
This is an Aragonite honey colored mineral specimen from the mines in Santa Eulalia,
Mexico. Each of the little columns appear to have crystals that stacked on top of each
other, and they branch out like coral does. Many pyramidal points formed on clusters
of twinned "fingers".  Aragonite is the second most common polymorph of natural
calcium carbonate (aka calcite).
This Aragonite specimen Measures 3.5 x 2.5 x 2.2 inches (89x63x57mm),
and weighs 0.6 lbs (268 grams).
