This 6.78 carat rectangular cabochon of ancient Roman glass shows a rare bi-color combination of vivid green and aqua blue. The cabochon measures 14.6 x 11.3 x 6.5mm with eye clean clarity and exceptional brilliance, which is a rare feat for glass crafted over 2,000 years ago. Bi-color pieces are among the rarest types of ancient Roman glass, and this piece's natural patina has been preserved with no treatment.

This glass originates from the crossroads of the Silk Road and was sourced from the Carmel Mountain region of Northern Israel. Under close inspection, you may see tiny air bubbles and specks of charcoal from the original kiln fire that have been trapped inside the glass for over 2,000 years. Roman glass reflects a time when artisans revolutionized the art of glassmaking, and pieces like this one traveled vast distances along the trade routes where cultures converged.

WHAT THIS STONE IS USED FOR

In the stone medicine space, ancient Roman glass is valued for both its elemental resonance and its deep cultural imprint. Formed nearly 2,000 years ago through the transformation of sand and mineral into glass, it holds the energy of its origin, where Roman innovation met Silk Road exchange, and it vibrates with the memory of transcontinental movement and the ingenuity of ancient artisans.

Energetically, this piece works as both a regulator and a clarifier. It helps disentangle internal chaos without collapsing flow, and it helps translate subtle internal truths into coherent outward form. This cabochon serves anyone refining how they express themselves, or recalibrating after periods of energetic excess or stagnation, and it offers a steady current of intelligent movement that is clear, calm, and composed. It also makes a museum-worthy center stone for a custom pendant.

VIBRATIONAL PROFILE

This bi-color piece emits the green and blue frequencies, and the aqua tone where the two colors meet resonates in the teal frequency.

Green Frequency: The vivid green portion gives this piece its green frequency component. The green frequency stimulates the pituitary gland, builds muscles and tissues, clears diseased cells, decongests the lungs, and eliminates germs and bacteria. It is the safest and most balanced clearing frequency in the vibrational spectrum, cleansing, detoxifying, and dissolving detrimental vibrations from the energy field. Salt carries a strong green vibration, which explains its long-standing use for purifying and preserving foods, spaces, and materials. Green marks the balance point of the visible light spectrum and the equilibrium of the manifested world.

Blue Frequency: The aqua blue portion gives this piece its blue frequency component, which supports clear, intentional communication. The blue frequency is effective for reducing fever, inflammation, pain, and infection, stopping bleeding, and building flexibility in the body. Enel recognized blue as a regenerator of the nervous system and used it for patients with high blood pressure, arthritis, and neuralgia. Energetically, blue is cooling, contracting, and sedative, restoring deep yin reserves and building vitality rather than stimulating yang energy. Rudolf Steiner associated blue with the Chemical Ether, the stage where the internal energetic blueprint is established before it materializes into physical form. Wilhelm Reich also observed that orgone energy glows blue in a vacuum.

Teal Frequency: Where the green and aqua blue meet, this piece resonates in the teal frequency. The teal frequency sits between green and blue on the vibrational spectrum, and embodies the qualities of both colors. Physically, teal supports detoxification and tissue clearing, while the blue aspect brings cooling and reduces inflammation and overactivity in the body. Energetically, teal is both dissolving and containing, reanimating and moving stagnant energy within the biofield or environment while stabilizing the entire field.

Together, the green, blue, and teal frequencies create a fluid yet organized profile that supports both internal coherence and outward expression, letting energy move where it has been stagnant without losing direction or purpose.
