Ancient Origins & Natural Formation

Organic hydrocarbons and ancient plant material became trapped within the crystal during formation, creating its distinctive smoky inclusions and fossil patterns.

Additional information

Lore

It is referred to as a “herkimer diamond” because of its sparking brilliance in natural light. It provides an energy of delicate harmony, enhancing distinct awareness and unbridled spontaneity. It helps one to "be". It is known as the "attunement stone".

It is a manifestation of pure, solidified spiritual light. They emanate a high, harmonious energy that positively sings on the upper levels of the vibrational spectrum. Herkimers emanate the brightest crystal light and they help purify one’s energy field and attune one to the white Light of Divine Essence. This is the stone that attracts angels as there is a bliss and rapture in the vibration of Herkimer ‘Diamonds’. Herkimers can also make dreamwork a truly wonderful experience.

About Herkimer Diamonds

Herkimer Diamonds are very pure, doubly terminated quartz crystals that are found exclusively in upstate New York in 500 million year old metamorphic sedimentary dolostone. They were first discovered in the Herkimer County area in the late 18th century and their extreme clarity and naturally bright crystal surfaces made them reminiscent of diamonds, leading to their name. The crystals themselves formed extremely slowly some 400 million years ago in small solution cavities or vugs contained deep within the dolostone. These vugs gave the ions of silicon and oxygen, the constituents of quartz, the time and space needed to form into the beautiful crystals that we see today.
