right -- origin Germany,  Ammonite fossils among other creatures in a slab, 18 inches by 16 inches

and a stump of petrified wood, (Arizona)

left,   ORTHOCLASE (or' - tho - klace)

A transparent to translucent, colorless, gray, light blue, bluish-gray, orange, brown, yellow or green species of the FELDSPAR group,

the principal variety of which is ADULARIA (precious moonstone). potassium-aluminum silicate (KAlSi3O8)
crystal system: monoclinic

Origin Swiss Alps

Orthoclase with Aegirite  -  (NaFe3(Si2O6))
Origin: Malawi, Africa

 ringt,  Orthoclase with Muscovite -
(Potassium Mica),  H2KAl3(SiO4)3

Origin: Brazil

Microcline (same chemistry as Orthoclase but crystalized  in Triclinic system, it is a polymorph of Orthoclase) 

with ALBITE (NaAlSi3O8), QUARTZ (SiO2), BROOKITE (TIO2)

Origin: Organ Mountain
New Mexico

Smoky Quartz Crystal Point, 13 inches in diameter.


The smaller crystal shows colored areas that are clay inclusions (clay deposited on crystal faces that were later over grown with more quartz deposits, these types of crystals are hydo-thermal in origin.)

Another hydo-thermal “Somky” Quartz crystal (twinned),  penetrated with Tourmaline crystals,  on a Topaz, Tourmaline and Albite feldspar matrix, 13 inches tall.

In the foreground it appears a blue topaz crystal Point was removed. It most likely was gem quality and being a natural blue color, was very valuable by itself. The Tourmalines are not gem quality and left in place.


At least 90% or more, of blue Topaz used in jewelry is colorless topaz that has been irradiated and then heat treated to turn it blue.  The surface of the quartz points have a coating of clay-like deposit without a quartz over growth. The origin of these specimens: Brazil
