Crystals & Minerals

You will receive 1 lot totaling 5 carats of the beautiful, clear Herkimer diamonds pictured. 

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

Chalcopyrite and sphalerite crystal clusters are minerals that are often found together in nature. Chalcopyrite is a copper iron sulfide mineral, while sphalerite is a zinc sulfide mineral.

Chalcopyrite crystals typically exhibit a brassy yellow color and have a metallic luster. They often form in cubic or tetrahedral shapes and can display iridescent colors due to thin surface layers of other minerals. Sphalerite crystals, on the other hand, can range in color from pale yellow to brown, and sometimes even black. They have a resinous to adamantine luster and can form in various crystal habits, including dodecahedral, tetrahedral, and cubic.

Chalcopyrite is believed to amplify energy, attract abundance, promote positive thinking, provide spiritual grounding, and offer protection. Sphalerite is associated with transformation, vitality, emotional healing, intuition, and manifestation.

Quartz crystals are among the most abundant and well-known minerals on Earth. It belongs to the hexagonal crystal system, and 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. 

Quartz is considered a “master healer.” It's said to amplify energy by absorbing, storing, releasing, and regulating it. It's also said to aid concentration and memory. Physically, clear crystals are claimed to help stimulate the immune system and balance out your entire body.

Quartz is also said to be a power gemstone that harmonizes and balances; enhancing energy and thoughts as well as purifying the spiritual, mental and physical. Quartz is associated with the crown chakra.

You will receive one of the Pseudomorphs pictured.

Pseudomorphs are mineral specimens that have the external shape of one mineral but are composed of another.  The pseudomorph goethite after marcasite forms when marcasite is exposed to oxidizing conditions and starts to oxidize and break down. As the marcasite breaks down, goethite replaces it in the crystal structure, preserving the shape of the original marcasite crystal. The resulting specimen appears as a marcasite crystal, but is actually composed of goethite.

The Farafra Oasis, in the White Desert, has been known for a number of years to deliver incredible pseudomorph specimens. The pseudomorphs occur within the Cretaceous Khoman Chalk, from which the White Desert derives its name.

These specimens are remarkable for their relatively sharp marcasite crystal forms in aesthetic crystal clusters. They are in excellent condition.  This collector's specimen is unique, of great quality and ready for display.

This is a beautiful specimen of golden brown Vesuvianite crystals on a white carbonate matrix from Mexico. A great addition to any collection! It was first discovered on Mount Vesuvius in Italy in the 18th century, hence its name.

Vesuvianite typically occurs as a green, brown, yellow, or blue-green crystal, and is often found in metamorphic and igneous rocks. The alternate name, Idocrase, is from the Greek eidos “form”, and krasis “mixture”, because Vesuvianite often appears to combine the crystal forms of other minerals. It is used as a gemstone.

This is an Adamite Crystals on Limonite matrix mined in Mina Ojuela, Mapimi, Durango, Mexico.  Adamite typically occur as small, brightly colored, prismatic or blocky crystals, or as crusts or aggregates. It is commonly found in association with other minerals such as limonite, calcite, and smithsonite.  Adamite colors include green, yellow, white, and reddish-brown. The green color of adamite is caused by the presence of traces of copper in its crystal structure.  One of the unique features of adamite is its strong fluorescence under ultraviolet (UV) light. It can exhibit vibrant green or yellow fluorescence.

Adamite was first discovered in 1866 in the Ojuela Mine in Durango, Mexico. It was named after French mineralogist Gilbert-Joseph Adam (1795-1881), who studied the mineralogy of the mine.

Adamite is associated with joy, creativity, and the balancing of energies. Some believe it can enhance one's ability to express themselves and promote a positive outlook.  It is highly valued by collectors for its bright colors and distinctive crystal habits and would be a great addition to any new or existing collection.

This is a beautiful cluster of clear quartz crystals on a carpet of green pistacite, also known as epidote. The epidote underneath are clearly visible through the quartz. 

Pistacite is a historical term once commonly used to describe a green variety of epidote, named for its pistachio-like color. While the term is still recognized among collectors and in older literature, it has largely been replaced in modern mineralogy by the more general name green epidote.

Pistacite (green epidote) is often associated with growth, release, and emotional healing. Some believe it helps clear negative energy and encourages letting go of patterns or emotions that no longer serve you. It’s thought to support personal transformation by boosting a sense of hope and forward movement, especially during times of change or recovery.

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