This 0.32 carat cushion cut chrome kornerupine from Tanzania shows the unmistakable teal color, a mix of mint green and light blue, that comes from chromium content in the crystal structure. The stone measures 4.2 x 3.5 x 3mm with brilliant light return and slightly included clarity, and it's completely untreated.

Kornerupine is a lesser-known collector's gemstone, and the chrome variety is its most sought-after color. Gem-quality kornerupine is rarely found above 1 carat, and the deposit that produced this material has now been fully depleted, so stones of this quality are getting rarer to find on the open market. Kornerupine's birefringence, meaning it bends light in two slightly different ways as it passes through the crystal, adds to the brilliance you see face up.

WHAT THIS STONE IS USED FOR

In the stone medicine space, kornerupine is known as a stone of spiritual clarity and personal truth. It helps you align with your authentic self and connect to higher levels of understanding, and it bridges the physical and the spiritual, offering grounding while facilitating introspection and insight. The mint green connects to renewal, growth, and the awakening of the heart, while the blue connects to calm, clarity, and the throat chakra, which makes this stone a strong ally for healing emotional wounds, fostering self-compassion, and aligning the heart with universal love.

One advantage of a faceted gemstone over a rough crystal is the culet, the pointed tip at the base of the stone, which acts as a focused energy director, much like the tip of a Vogel Crystal. By pointing the culet directly at the body, you can concentrate and deliver the stone's vibrational frequencies into a specific point instead of letting them radiate outward in all directions. For collectors, this cushion cut chrome kornerupine anchors a rare stone collection, and in fine jewelry it suits a delicate accent or small center stone.

VIBRATIONAL PROFILE

This kornerupine emits the green and blue frequencies, resonating with the heart and throat chakras.

Green Frequency: The mint green in this stone gives it 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 light blue in this stone gives it its blue frequency component. 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.

Together, the green and blue frequencies pair renewal and emotional healing with calm and clarity, which is what gives chrome kornerupine its balanced, harmonizing character.
