6.5" Quartz crystal with ajoite inclusions, Messina, Limpopo Province, South Africa

Ajoite is a very rare copper-related silicate which is sometimes found as inclusions in quartz. Ajoite has a rich turquoise blue color which, at its best, shows well through the natural, unpolished faces of the crystal. Sometimes coatings on the faces of the quartz crystals obscure the ajoite, in which case they are polished to a smooth, transparent finish. Ajoite is named after its main location in the Ajo District of Pima County, Arizona. It is a secondary mineral that forms from the oxidation of other secondary copper minerals. Ajoite's color can range from blue green to light green. The luster is dull to resembling glass, thus it could be transparent to translucent. Its cleavage is perfect with a hardness of 3.5. Its streak is pale greenish white. Ajoite can also be found in at the New Cornelia Mine, Ajo District, Pima County, Wickenburg and Maricopa County within the United States, and the Messina District in South Africa.

A Note from the TOO GOOD TO BE TRUE DEPARTMENT:
CORRECTION ON THE AJOITE PSEUDOS


3.6" Neon Aqua-Blue CHRYSOCOLLA CRYSTALS Pseudo Malachite/Azurite D.R.Congo for sale

I knew I should have trusted my initial instincts. It was early February out in Tucson, and I saw a specimen labeled "Ajoite Pseudo after Azurite" in a dealer's display case. The problem was that I had been selling the exact same material for several years, and had always labeled it as "Chrysocolla Pseudo after Azurite." Max Mpuye had been selling me great specimens of this colorful material since it first appeared at the East Coast Show in 2012. Here's how I described one of the specimens:

WHAT IS AMMOLITE?

Ammolite is an organic gemstone made from the nacre-like shells of fossilized ammonites which are found in Alberta, Canada. Its primary feature is its brilliant, iridescent colors, which are result of the material's opal-like qualities. Ammolite is mainly composed of aragonite, CaCO3. It is also known as aapoak, gem ammonite, and korite (a trade name). Ammolite is found on found on the shells of fossil ammonites from the Upper Cretaceous period (135 million years old). Ammolite is rare, occurring in only one small area near St. Mary River in southwestern Alberta, Canada.

1.5" Fine Gemmy Green FLUORAPATITE Sharp Terminated Crystal Panasquiera

The name apatite comes from the Greek word apatein, meaning to deceive, because of its similarity to so many other minerals. Ironically, it is actually 3 different minerals, and the precise species of this phosphate mineral depends on which of 3 ions is predominant:

  • If fluorine is the primary ion, then it is fluorapatite - Ca5(PO4)3F
  • If chlorine is the main ion, then it is chlorapatite - Ca5(PO4)3Cl
  • If the hydroxyl group is dominant, then it is hydroxylapatite - Ca5(PO4)3OH

However, in the crystal lattice these ions can substitute freely, so all 3 are typically present in any one specimen, making it impossible to distinguish them without x-ray diffraction or other analytical methods. Most collector forms of apatite are fluorapatite.

Apatite is the most common phosphate mineral. It is the primary source for phosphorus, a fertilizer required for plant growth. Also, the teeth and bones of humans and most animals, are composed of hydroxylapatite.

2.8" azurite sun on kaolinite

Azurite is a soft, deep blue copper mineral produced by the oxidation weathering of copper ore deposits. It is a favorite amongst mineral collectors because of its rich blue color and wide availability in a variety of forms and color variations, from sharp, lustrous brilliant dark blue crystals to thick, rich, colorful royal blue coatings on matrix.

Azurite suns are a unique form of azurite that have been found in only one place in the world: the Malbunka Copper Mine (formerly the Namatjira prospect) near Areyonga, beneath a hill in the desert in Northern Territory, Australia. Malbunka is the name of the Aboriginal clan that owns the land.

12" 3-Chamber celestite geode, Sakoany, Madagascar

Since 1967, the Sakoany area on the northwestern coast of Madagascar has yielded hundreds of tons of geodes lined with beautiful blue celestite (also known as celestine) crystals, the world's finest examples of the species. The geodes and crystals from this area are very beautiful and colorful, making them very popular with mineral collectors.
