Metaphysical Properties: Optical Calcite is associated with extreme clarity, insight, and energy amplification. Known as a stone of double refraction, it helps reveal hidden meanings, clear energetic blockages, and promote emotional balance and mental focus.
Disclaimer: Gemstone identification is based on visual assessment only, considering cleavage, transparency, colour, and texture. Stones have not been laboratory tested unless explicitly stated. Whilst every effort has been made to identify each gemstone accurately, identification should be considered our best professional opinion rather than a certified mineralogical determination. Metaphysical properties are based on traditional beliefs and are not scientifically proven.
