Polished Face Opal and
Feldspar Nodule from Brazil

Here's an excellent Old Stock Polished Face Nodule of Opal and Feldspar
conglomerate we procured from a Brazilian Mineral dealer in 2004. We cut
several slabs (listed below on this page) which we are selling as rough cut
lapidary material. This specimen was flat cut on bottom for display and had the
face cut polished in our shop. There are what appear to be natural fractures in
the face, but the slabs cut from this stone are very stable and solid.
This rare stone has been sold by jewelers as Blue Liberite and Que Sera
Stone. It is mainly sold by opal dealers.

This specimen weighs 61.6 oz or 3.85 lbs (1748g)
and measures 6.3 x 3.6 x 3.3 inches (16.1 x 9.3 x 8.4cm)

This specimen can be a nice large cabinet display or it can be cut into many
more slabs for making lapidary cabochons. This unique stone is made up of a
conglomeration of minerals, primarily Opal and Feldspar. This stone is found
only in Brazil and is a mixture of different types of stone, including Quartz,
Calcite, Kaolinite, Iron oxides, Magnetite, Clinozoisite and Leucozene.

Old Stock Indian Paint Rock Slab
from Death Valley
This Indian Paint Rock slab comes from Death Valley, California. This location has been closed to collecting since
Death Valley became a National Park and this beautiful material is getting rather scarce. Indian paint rock is a
sedimentary rock. It is a type of jasper/sandstone found in Nevada and California. The interesting patterns and colors
are created by trace amounts of iron and manganese being drawn into the rock by capillary action through minute
cracks in the stone. This Death Valley Indian Paint rock slab is absolutely gorgeous! It has very attractive and unusual
colors (reddish/brown, grey, purplish, tan and black) and has outstanding and artistic patterns (all natural, nobody
painted on this stone). This material is a soft rock (3 to 3.5 Mohs) and polishing results in a satin sheen rather than the
glossy one.

Geologists say it is considered to be a type of jasper, but the grains are so loose, so it has the characteristic of having
a lower hardness similar to dense sandstone. The light color is a sedimentary sandstone, the black is manganese, and
the red is iron.  The hardness varies, depending on where it is scratched.  This was collected from Death Valley, CA
back in the 1970s. This area was declared to be a National Park in 1992 and the area was closed to collecting. The
area has been almost completely hunted out.  Other small deposits have been found, but they are few and far between
and are closely guarded due to the high price of these stones. The term "Indian Paint Rock" is the name given to these
rocks due to the color patterns.  There is no specific geologic name due to the many minerals that make up its
composition. This slab has been in our collection for many years

Weighs 3.92 oz or 0.245 lb (111g) Measures 6.8 x 2.2 x 0.2 inches (173 x 58 x 5mm)

Apache Picture Jasper Slab
Apache Jasper is also known as Mimbres Valley Desert Picture Jasper.   Mimbres Valley is in
New Mexico. Apache Jasper often depicts an image that looks like the area it was mined from,
that is desert with brush growth.  The bush looking images are sometimes dendrite growths.  A
Native American tribe, the Mimbres, lived in the area where this jasper is mined.  The tribe
disappeared about a thousand years ago.  It is presumed they merged with the Apaches.
