3.43 ct. Astrophyllite Cabochon

This 3.43-carat astrophyllite cabochon, measuring 10.4 x 8.4 x 5 mm, is cut from rare old-stock material sourced from Russia. It features the signature bronze-to-copper metallic flashes of astrophyllite, an iron titanium silicate known for its radiating, blade-like inclusions that shimmer and shine through a dark matrix.

Astrophyllite is not commonly available in fine cabochon form, particularly from historical sources and old-stock material. This piece showcases a dense, high-contrast matrix punctuated by bright, reflective blades, ideal for gemstone collectors, jewelers and jewelry artisans, and energy practitioners who work with specimens that are vibrationally potent.

This stone vibrates within the black band of the universal vibrational / electromagnetic spectrum. Black-band frequency is associated with absorption, stabilization, and the containment of energy. Black-band stones are used in vibrational work for their capacity to absorb energetic toxicity, consolidate energetic fields, and create strong protective boundaries.

Astrophyllite gets its name from the Greek words astron, meaning “star,” and phyllon, meaning “leaf” and is a reference to its distinctive crystal habit. It often forms in radiating, star-like blades that resemble metallic leaves spreading outward through its host rock. This star-leaf structure, combined with its deep, submetallic luster, creates a striking contrast against the typically lighter matrix it grows within.

VIBRATIONAL FREQUENCY PROFILE

This stone resonates within the black band of the vibrational spectrum, which is associated with the consolidation, absorption, and grounding of energy across multiple levels:

• Physical Level: Black-band stones help detoxify by chelating and drawing out energetic and material toxicity. They are often used to absorb harmful energetic residues from the body and environment.
• Energetic Level: The black frequency consolidates scattered energy, helping to seal the aura (biofield) and anchor one's intention into form. It stabilizes the energy field and enhances one's ability to hold vibrational states without any energy leakage.
• Emotional/Mental Level: Black brings qualities of calm, rest, and sobriety to one's life. It supports deep introspection, detachment from reactive emotional patterns, and the ability to observe from a centered, quiet place.
• Spiritual Level: Black resonates with archetypal Yin energy and spiritual initiation. It is connected to the Mystery, the Void, and the field of infinite potential before coming into physical form. It holds the power of death and rebirth, supporting processes of transformation, release, and the return to inner stillness.

METAPHYSICAL PROPERTIES

Astrophyllite is used to bring out deep insight and help with conscious integration of insights that come through. Astrophyllite is often used to support self-awareness and inner alignment. It helps bring what has been beneath the surface into clearer focus, offering insight into patterns or aspects of the self that may have been overlooked. Its radiating inclusions reflect its ability to illuminate what is hidden, whether within the psyche, the body, or more subtle layers of the energetic field.

Practitioners use astrophyllite to:

• Absorb and transmute detrimental energy and energetic residue
• Assist with spiritual boundary-setting and psychic hygiene
• Support grounding during transformational or initiatory phases
• Encourage honest reflection without being emotionally reactive
• Illuminate patterns that are ready to be resolved and integrated

With its black band resonance and inner metallic structure, this stone supports the alchemical movement of energy from chaotic and dissonant to clear and coherent. It helps anchor the subtle body during advanced energy work, and offers a field of containment for deep processing and energetic clearing.

A powerful ally for those doing shadow work, vibrational detoxification, or high-frequency integration, this small but potent cabochon holds the capacity to protect, stabilize, and reflect the unseen. Because of this, it's a great piece for setting into a ring or pendant, using as a central altar stone, or making a gem elixir.

*Please note that most of our photography and some videos are done with a 2x to 10x macro lens, so inclusions may be visible in the photos and videos, but you will not see them with an unaided eye. While we pride ourselves on our photography that depicts actual color and clarity, colors may be slightly different depending on your screen.
