This beautiful piece has a tiny crystal cavity with a great Agate design throughout.
Just gorgeous! Another photo

Agates mostly occur as nodules in volcanic rocks or waters containing
Silica in solution which is 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. It is very unlikely that you would
ever find an exact duplicate of any type of Agate, Brazilian or other.

addition to any collection.

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.

The Ocean Jasper deposit, even though it was found only a few years ago,
is nearly gone and the material is becoming hard to find. The deposit
formed as a Rhyolite flow but has been completely silicified. The Rhyolitic
eyes or orbs come in an astonishing array of colors and color combinations.
The back ground can be white, pink, green, red, or yellow. Botryoidal formations
as well as white and deep green druzy are also common. This deposit was discovered
at the edge of the ocean. It can only be seen and collected at low tide. The
area has no road so the material must be transported to civilization by boat.
Several other types of jasper are found in that area now but the orbicular
Jasper is gone.

Amethyst is a purple variety of Quartz often used as an ornament.
It occurs in color from a light, slightly pinkish violet to a deep grape
purple. Upon exposure to heat, Amethyst generally becomes yellow, which some refer
to as Citrine or "burnt" Amethyst. It is widely distributed
as a mineral, but fine, clear specimens that are suitable for cutting as
ornamental stones. |

Granite is a common and widely occurring type of intrusive igneous
rock. Granites are usually medium to coarse grained, occasionally with
some individual Crystals. It can be pink to dark gray or even black
depending on the chemistry and mineralogy. It is a hard and tough
substance is used mostly in construction and landscaping.

Geodes are geological rock formations which occur in
sedimentary and certain volcanic rocks. They are essentially rock cavities
or vugs with internal Crystal formations or concentric banding. The
exterior is generally Limestone while the interior contains Quartz
Crystals and/or Chalcedony deposits. If the Geode is completely filled
with Crystal, being solid all the way through, it is then called a nodule.

Here is something new and
different; an excellent example of Amphibole Quartz from Bahia, Brazil.
The Amphibole Quartz has amazing clarity showing the wonderful inclusions
of Limonite (yellow), Hematite (red), Kaolinite (white) or Lithium
(pink). This fascinating Quartz crystal is 6" long x nearly 3 1/4" x
almost 2 1/4" with excellent colorful inclusions. The multi-faceted
crystal is all natural with a very nice finish. Like most Quartz,
pictures just don't do it proper justice!

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. |

A Meteorite is a natural object originating in outer space that
survives an impact with the Earth's surface without being destroyed. There
are 3 types of meteorites: stony, which are mainly composed of Silicate
minerals; Iron, which are largely composed of metallic Iron-Nickel; and
stony-Iron, which are composed of both types of media.
Peridot is one of the few gemstones that occur in only one color,
an olive green. The intensity and tint of the green, however, depends on
how much iron is contained in the crystal structure, so the color of
individual peridot gems can vary from yellow- to olive- to brownish-green.
The most valued color is a dark olive-green.

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.
