World famous Herkimer Diamonds are beautifully doubly-terminated quartz crystals already faceted by nature. The bedrock in which the crystals are found began forming approximately half a billion years ago in a shallow Cambrian sea that lapped against the southern shores of the ancestral Adirondack Mountains. They make attractive cabinet specimens, either in groups of loose crystals, singly, or in a matrix, all just as they come from the ground. The most perfect crystals, are often used as display pieces in jewelry.

Jewelry, Gems, Rocks and Minerals from all over the world can be discovered in the diamond mines shop. Over 80 designer lines of Herkimer Diamond jewelry are available. Also have finishes in citrine, amethyst, ametrine, topaz, tavelite, tanzanite, sapphires, aqua, aura, smoky quartz, peridot, pearl, rubies, garnet and more!

Herkimer Diamonds are believed to be effective for healing, meditation and spiritual purposes. It is thought that the double terminated points allow for multiple locations for energy to enter and exit from the crystal, resulting in a more powerful energy flow. Visit our gift shop and discover items used for these purposes.

Grade AA (Vial Size, 1/8”, 1/4”, 3/8”, 1/2”, 5/8” 3/4”, 7/8”, 1”, 1 1/8” and up)

Crystals in this group are flawless to the naked eye. They are extremely rare and become more so in larger sizes. Typically used for collection and high end jewelry.

Grade A (1/8”, 1/4”, 3/8”, 1/2”, 5/8” 3/4”, 7/8”, 1”, 1 1/8” and up)

These gems have only slight flaws. They may have small attachment marks, inclusions, or fractures which do not significantly take away from the overall clarity of the diamond. These flaws should not exceed more than 5% of the total diamond. Both termination points should be present. Typically used for multiple jewelry products.

Grade B (1/8”, 1/4”, 3/8”, 1/2”, 5/8” 3/4”, 7/8”, 1”, 1 1/8” and up)

A crystal in this category should retain the general Herkimer Diamond shape. It may be cloudy from internal fractures, have large attachment marks, and / or termination point damage. The diamond should have reasonably good appearance. Typically used for loose diamond resale, pouches, pillows, gifts, and bell capped jewelry.

Grade C (1/8”, 1/4”, 3/8”, 1/2”, 5/8” 3/4”, 7/8”, 1”, 1 1/8” and up)

Natural Herkimer Diamond Special Specimen Descriptions

Metaphysical Stones: These are numerous in quality, size, and type. Please inquire.

Enhydros: Herkimer Diamonds with hydro inclusions are truly unique. The value of an enhydro Herkimer Diamond is dependent on the size of the inclusion, size, and overall quality of the diamond, and movement of “floater” bubbles or “sinker” specks of anthraxolite inside the inclusion. A nice hydro inclusion in good quality diamond can make the crystal worth as much as five times of what the diamond would be worth without the inclusion.

Solid Inclusions: Many Herkimer Diamonds will have solid inclusions. Black anthraxolite is the most common of solid inclusions found in the diamonds. The presence of anthraxolite inside a diamond may enhance its beauty. Other minerals which may be found as solid inclusions in the diamonds include iron pyrite, dolomite crystals, calcite, sphalerite, and garnet. Value of a diamond with a solid inclusion is usually contingent on the aesthetics of the inclusion.

Twins & Doubles: Often, two diamonds which are attached to each other are found. These sometimes result in very interesting configurations. Occasionally, two attached diamonds that look very much alike are called “Siamese Twins”. Rarely, you may see what is called “Penetration Twins”. These are two like diamonds which have grown together and the c-axis of its twin. It is not uncommon to find a diamond which ahs another smaller one attached. These are sometimes called “piggy-backs”.

Clusters: These are groups of diamonds which have grown together. A cluster can make a spectacular display piece. The majority of the time, a group of diamonds which formed together will break apart during the extraction process. When the group appears to have a great deal of aesthetic potential, it can be well worth your time to reconstruct the cluster. A high quality epoxy adhesive may be used to glue the group back together. The diamonds can be puzzled back together by matching the attachment marks. The value of a cluster is dependent on its aesthetics. A nice cluster is valued as much as five times what the value of the diamonds alone would bring. Then again, it may not be worth anymore that the diamonds would if sold individually.

Tabulars: These are extremely rare. Only one attractive tabular is found in every five hundred diamonds. A tabular will have two opposing center facets which have grown much larger that the other faces of the diamond. This gives the crystal a flat tabular appearance.

Color Veils: Occasionally, healed fractures inside a diamond will refract a brilliant spectrum of rainbow colors when it is hit by light. The diamond is worth even more if the healed fracture cannot be seen with the naked eye. These may also be called “rainbows.”

Smokies: A smoky crystal will have a very slight gray to black discoloration inside. This discoloration sometimes will look like thin clouds of smoke settled inside the diamond. This smoke is disseminated anthraxolite.

Skeletal: A skeletal has depressed cavern in the center of one of the termination faces. Skeletal have an interesting pattern of multiple fracture lines running parallel with two or more sides of a face on a diamond. The lines appear to have occurred during the growth stage and are usually spaced in such a manner to give a three dimensional, holographic look when observed through on face.

Phantoms: A phantom crystal is one in which another crystal formed inside a larger crystal. The phantom crystal trapped inside can often easily be seen with the naked eye. These are very rare.

Other Specimens: There are other specimens of Herkimer Diamonds which are rare and valuable. Some diamonds formed with more or less the normal eighteen face surfaces. This can result in some very interesting shapes, such as cubicle, rectangular, or octagon configurations.

Matrix: Herkimer Diamonds in the matrix can also be valuable. Unique matrix specimens may have Herkimer Diamonds on matrix with calcite, drusy quartz, or iron pyrite. Clusters in the dolomite matrix can also be very beautiful.

Pockets: Although the most popular method of prospecting for loose Herkimer Diamonds is by breaking them out of a single rock, domes pocket mining in the table – layer of rock is usually very rich with diamonds. Some pockets are known to contain thousands of diamonds. Pockets or cups can be up to six feet in diameter and usually no less than one foot. The dome-like tops of the pockets are often lines with small, white cubic-shaped dolomite crystal. Occasionally, the top will be beautiful black drusy quartz.

Pockets containing diamond crystal are never the same either in size or in quality. Most pockets, as a rule, will contain diamond crystals of various sizes. Some pockets may contain large crystals ranging in size from four to eight inches long and three to four inches wide. Other pockets with medium sized crystals range in size from an inch and a half to three to four inches long and a half-inch to two inches wide. Micro crystals are always found.

As the crystals move up in size, they tend to become less clear or more translucent than transparent. Some crystals contain anthraxolite or decayed plant life. The anthraxolite resembles bits of black coal within the crystal. A special discovery would be an enhydro crystal. Enhydros contain anthraxolite floating in a water bubble. Twins, double, cluster, tabulars, smokies, skeletals, and phantom crystals are all valuable specimen.

Please Contact Us for special specimen pricing.
We sell only 1 or 2 pockets per year. Price is dependent upon quality of pocket and size of pocket.
