Herkimer Diamonds, despite their name, are not diamonds at all. These captivating gemstones are a unique variety of double-terminated quartz crystal, renowned for their exceptional clarity and brilliant luster. First discovered in Herkimer County, New York, they have become a popular alternative birthstone for April, alongside the traditional diamond. Their distinctive formation and striking appearance have captivated gem enthusiasts and collectors for generations, establishing them as a significant gemstone with a fascinating history and growing appeal.
History and Lore
The story of the Herkimer Diamond begins in the late 18th century, with initial discoveries made in the towns of Little Falls and Middleville, New York. This led to the alternative names of “Little Falls Diamond” and “Middleville Diamond,” reflecting their place of origin. While often referred to as diamonds due to their diamond-like shape and multiple facets, it was quickly recognized that these were, in fact, a form of quartz crystal.
The enduring appeal of the Herkimer Diamond is reflected in its popularity as a tourist attraction. Visitors frequently participate in mining tours in Herkimer County, experiencing the thrill of uncovering these crystals firsthand. This hands-on experience has fostered a dedicated community of enthusiasts and collectors. Notably, the Herkimer Diamond is considered the most exported stone from the United States, demonstrating its global recognition and demand.
Beyond their geological origins, Herkimer Diamonds have accumulated a rich tapestry of metaphysical associations. In various belief systems, clear crystals are linked to powerful deities. They honor Kundalini, the Hindu Life Force Goddess, and Latona, the Roman Goddess of Light. Furthermore, specific angels are associated with the stone, with different angels linked to particular dates and purposes, as detailed in esoteric tables. Angerona, the Roman Goddess of Silence and the Goddess of the Winter Solstice, is also connected to Herkimer Diamonds, representing protection of secrets and the promise of renewal.
Geological Formation and Sources
Herkimer Diamonds are formed within dolomite, a sedimentary rock, where pockets or vugs develop. These vugs provide the space for quartz crystals to grow. The unique double-terminated shape, meaning the crystal tapers to a point at both ends, is a result of the undisturbed growth environment within these pockets. The crystals develop naturally occurring facets, giving them a sparkling, diamond-like appearance without the need for cutting or polishing.
Originally, Herkimer Diamonds were exclusively found in Herkimer County, New York, giving the stone its name. However, subsequent discoveries have expanded their geographical range. Today, they are also sourced from locations including Arizona, Afghanistan, Norway, Ukraine, and China. While found in these various locations, the stones originating from Herkimer County, New York, are considered the “true” Herkimer Diamond. Quartz, the mineral family to which Herkimer Diamonds belong, is also found in Maine, Arkansas, Virginia, Pennsylvania, North Carolina, and California.
Gemological Properties
Herkimer Diamonds are a variety of quartz, with a chemical composition of SiO₂. They are typically clear and colorless, though variations can occur. These variations include stones exhibiting smoky hues, spotted patterns, or even fluorescence under ultraviolet light. The clarity of Herkimer Diamonds is often exceptional, ranging from A to AAA, with some specimens displaying remarkable transparency and visible inclusions.
The defining characteristic of a Herkimer Diamond is its double termination and naturally formed facets. These facets, often numbering eighteen, contribute to the stone’s brilliance and give it a diamond-like appearance. The “Salt and Pepper” variety features naturally occurring spotted areas within the clear crystal, creating a unique and visually appealing pattern. No two “Salt and Pepper” stones are exactly alike.
While the provided sources do not detail specific refractive indices or hardness measurements, it is understood that, as a form of quartz, Herkimer Diamonds share the general properties of quartz. This includes a Mohs hardness of 7, making them relatively durable and suitable for jewelry.

The stone’s association with various angels further enhances its metaphysical significance.

The connection to goddesses like Kundalini and Latona reinforces the stone’s association with light, life force, and spiritual awakening.
Care and Cleaning
Due to their hardness of 7 on the Mohs scale, Herkimer Diamonds are relatively durable. However, like all gemstones, they require proper care to maintain their brilliance.
