Crystals & Minerals

This is a specimen of Star Mica or Muscovite cluster.  These clusters show crystals that grow in sheets or book formations.  It is silvery gold with good transparency when held up to the light.  The name Muscovite comes from the term Muscovy Glass which was a name for the thick sheets of Mica used as a substitute for glass Russia. The name Mica is derived from the Greek word that means to split.

On this nice specimen, the matrix faces are covered with beautiful golden yellow point stars of muscovite mica, a typical shape for this rare mica formation. The stars are the result of twinning; the points show a bit of wear but this does not detract from the beauty of such a piece.

This beautiful cluster combines tetrahedrite, cubic and crystallized pyrite matrix and tiny terminated quartz crystals. 

Tetrahedrite crystals are fascinating minerals known for their distinctive tetrahedral shape and shiny, metallic luster.  It typically forms in well-defined tetrahedral crystals, which can be grouped in clusters.  The color range includes shades of metallic gray, black, and sometimes reddish hues due to the presence of copper and other trace elements. Tetrahedrite is commonly found in hydrothermal veins and is often associated with other minerals such as quartz, galena, and sphalerite.

Tetrahedrite is believed to promote emotional healing and provide a protective shield against negativity. It is thought to enhance creativity and clarity, helping individuals connect with their inner selves.

This top specimen is in very good condition. Would be a beautiful addition to any new or existing collection.

This is a beautiful, fully terminated thumbnail sized Quartz Point. 

Quartz crystals are among the most abundant and well-known minerals on Earth. Quartz belongs to the hexagonal crystal system. It typically forms six-sided prismatic crystals with a pointed termination. Its crystals can be colorless or exhibit a wide range of colors. The color variations are often due to the presence of impurities or trace elements during the crystal's formation. Quartz is transparent to translucent. 

This specimen would be a beautiful addition to any new or existing collection.

Its crystals can be colorless or exhibit a wide range of colors. The color variations are often due to the presence of impurities or trace elements during the crystal's formation. Quartz is transparent to translucent.

Quartz from this quarry is known as the best of its kind. These specimens have a unique brightness and surface sparkle preferred by collectors around the world.  The crystals are intergrown with many others in jackstraw groups which are not attached to matrix: giving you an unlikely-looking floater specimen. The specimen is in very good condition.

This is a 4.25 carat, 8 piece lot of beautiful little Herkimer diamonds.  They measure 4.7-7.5 mm in length and each of them have multiple terminated points. 

Herkimer Diamonds are beautiful double-terminated quartz crystals which are found mainly in Herkimer County, New York. Incredibly, these phenomenal gemstones are believed to be close to five hundred million years old. The crystals are magnificent works of nature found in the rock, appearing to have been precision cut by man and having a diamond-like geometrical shape; thus, the name Herkimer Diamond.  Many collectors believe the Herkimer Diamond should rival a true diamond and their reasoning for this is that a true diamond found in the rough is exactly that, a rough appearing glass-like stone. The diamond must be painstakingly cut by man to give it smooth faces and a geometrical shape.

In fact, Herkimer Diamonds are not diamonds.  A true diamond is one of the hardest elements known to man, scoring a ten on a one to ten hardness scale.  Herkimer Diamonds are harder than all quartz crystals. They fall at about 7.5 on the Mohs hardness scale, giving the real diamond a close race.  For comparison, many man-made steels barely score a seven on the hardness scale.

This stone is said to energize, enliven, and promote creativity.  The smaller, exceptionally clear stones are said to be powerful attunement crystals, stimulating psychic abilities, such as clairvoyance, spiritual vision, and telepathy.  It is also said that Herkimer attunes people and links them together when they have to be parted if each person has a stone
