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)
Silver Lace Dendritic Onyx slab from Calico, California
Silver Lace Onyx is a rather scarce stone. This slab is from the Silver Lace Onyx Mine in the Calico Mountains, near the town of Calico, in Southern California. The Silver Lace Onyx Mine was shut down many years ago. The minerals in this slab are of excellent quality and the patterns are visually stunning. The black color dendrites in the lacy pattern are real natural silver. This unique stone from California displays gray, black, and white in bands with dendrite formations resembling tiny trees. This slab has been in our personal collection for many years.
This Slab weighs 3.78 oz or 0.236 lb (107g) and measures 4.6 x 3.2 x 0.23 inches (119 x 82 x 5.9mm)
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.
Weighs 1.34 oz (38.5g) and Measures 4.2 x 1.1 x 0.24 inches (106 x 29 x 6.2mm))
