polish. The sphere has a soft Rose Pink color with nice various lighter shades of
Pink in the nice banding and throughout the sphere. These type of spheres are hard to find anywhere and due

Rhodocrosite is a Manganese Carbonate mineral. It is typically a
rose-red color, but impure specimens can be shades of pink to pale brown.
It is used as a key component of low-cost stainless steel and certain
Aluminum alloys. Quality banded specimens are often used for decorative
stones and jewelry, although it is relatively soft and difficult to cut.

clear to the eye with very nice sparkly inclusions. A true beauty for
the sphere collector. Another Photo
Quartz is the second most common mineral in
the Earth's continental crust. It is mainly composed of Silica or Silica
based minerals. Although Quartz is known by a variety of names, the
most important distinction between types of Quartz is that of macro-crystalline,
individual crystals visible to the unaided eye, and micro-crystalline, where
aggregates of crystals are only visible under high magnification. There
are many forms of Quartz including Chalcedony, Amethyst, Citrine, and Carnelian
which are results of mineral impurities or heat treatments.

Agates mostly occur as nodules in volcanic rocks or waters containing
silica in solution possibly derived from the decomposition of silicates in
the lava. The siliceous matter is deposited in regular layers resulting
in the banded or striped formation.

Selenite, also known as Satin Spar, Desert Rose and Gypsum Flower, are
the four Crystalline varieties of Gypsum. It is a very soft material
composed of Calcium Sulfate. Selenite is often transparent and colorless.
If color is present it is often due to impurities or presence of other minerals.

This is a rare and unusual sphere made from Tiger-Eye from Africa. This
sphere shows nice areas of flashy Gold Tiger-Eye. It is different
than most Tiger-Eye as it exhibits areas of Gold flash in different areas
as it is rotated in the light. It has nice colors and a great polish.
It measures 2 1/8" in diameter. A nice addition to any the collection.
Another photo
Tiger-eye is a member of the quartz family, a cryptocrystalline variety.
It is one of the chatoyant varieties of gemstones. Due to the fibrous
structure of the gemstone, as light reflects within the thin parallel fibrous
bands it exhibits a changeable silky luster or chatoyancy. It occurs
naturally in colors of gold and blue.

Anhydrite is an anhydrous, calcium sulfate mineral. The color
is usually white but can also be grey, blue or purple. It can have a
pearly luster. When exposed to water, Anhydrite can readily transform
to the more common occurring Gypsum. It can be found in deposits of
Salt, Gypsum and is associated with Calcite, Halite, Galena, Molybdenite and
Pyrite.
Serpentine is a group of common rock forming hydrous Magnesium Iron
Silicate minerals. It can contain minor amounts of Chromium, Manganese,
Cobalt or Nickel. Serpentine may refer to over 20 different varieties
that belong to the Serpentine group and the most common are Antigorite,
Chrysotile and Lizardite. The color is often green and may have a mottled
or scaly appearance. |

This is a very pretty multi colored Fluorite sphere. This
sphere measures 2" in diameter and has a good polish. This sphere is
unusual in that it is mostly Green with Purple accents.
Another photo
Fluorite, also known as fluor-spar, is a mineral composed of Calcium Fluoride.
It is a widely occurring mineral and is often found with metallic minerals
such as Galena and Sphalerite, but also with Barite, Quartz and Calcite.
It may fluoresce strongly in ultraviolet light. Although blue is the
most common color, it can also be red, purple, green, yellow and white.

Calcite is a Carbonate
mineral that is most widely distributed on the Earth's surface. It is
a common constituent of sedimentary rocks with Limestone in particular.
A Calcite formation can take on many different shapes and sizes which is dependent
on the location, ground water occurrence and temperature. Calcite is
usually white or colorless but can be gray, red, yellow, green, blue, violet,
brown or black. The deeper the color is usually indicative of the definitive
impurities from the earth or water.

Marble is a metamorphic rock consisting of Limestone
but composed mostly of Calcite. It is used extensively for sculpture,
building materials and has many decorative uses. The pure white Marble
is probably the most common form known, but the characteristic swirls and
veins of many colored Marble varieties are usually due to various mineral
impurities such as Clay, Silt, Sand, Iron Oxides or Chert.

Here is a very beautiful Black Silver Sheen Obsidian sphere. It
measures nearly 2 7/8" in diameter with a very nice polish. The sphere
is Black with a very visible sheen iridescence
in the light. This material is from Mexico. Just amazing.
Another Photo

Obsidian is a type of naturally-occurring glass
formed as an extrusive igneous rock. It is produced when felsic lava
erupted from a volcano, cools rapidly through the glass transition temperature
and freezes without sufficient time for Crystal growth. Because of the
lack of Crystal structure, Obsidian blade edges can reach almost molecular
thinness, leading to its ancient use of projectile points (arrow heads), and
its modern use as surgical scalpel blades.
