ICELAND SPAR CALCITE PRISMATIC CRYSTAL (38.9 ct) | HANDCRAFTED PENDANT & 18K GOLD-PLATED NECKLACE
A gemstone that transforms light into a visual experience. Weighing 38.9 ct, this transparent Calcite—known as Iceland Spar—reveals a vitreous luster, internal reflections, and the fascinating phenomenon of double refraction. Its prismatic crystal is showcased in an original wire-wrapped pendant paired with an 18k gold-plated necklace, creating a luminous, scientifically intriguing, and unique piece of jewelry for those who appreciate natural minerals and exclusive design.
ORIGIN & THE SCIENCE OF BEAUTY
"Iceland Spar" is the traditional name for colorless or transparent Calcite of optical quality. It is a form of calcium carbonate (CaCO₃) that crystallizes in the trigonal system and exhibits perfect rhombohedral cleavage. The term "Iceland Spar" refers to the optical variety and does not, in itself, confirm that the specimen originated in Iceland.
Calcite can form through the chemical or biological precipitation of calcium carbonate within limestone rocks, cavities, caves, and hydrothermal veins. When it grows with high transparency and minimal inclusions, it becomes particularly prized by collectors and optics enthusiasts.
Its distinguishing feature is birefringence: as light passes through the crystal, it splits into two rays, creating a visible doubling of words, lines, or images. This property has contributed to studies on polarization and the development of instruments such as the Nicol prism. Every plane, veil, reflection, or tiny rainbow captures the specimen's structure and natural history.
With a hardness of 3 on the Mohs scale and perfect cleavage in three directions, it is a delicate mineral, best suited for jewelry intended for careful, occasional wear. SYMBOLISM & ENERGY – TRADITIONAL PERSPECTIVE
In contemporary crystal traditions, Optical Calcite symbolizes clarity, perception, discernment, and the ability to view choices from new perspectives. It is also associated with meditation, the expansion of consciousness, optimism, and the symbolic amplification of intentions. These associations are cultural and spiritual; they do not represent scientifically proven medical or therapeutic effects.
CHAKRAS
It is traditionally linked to the Crown Chakra, which is associated with consciousness, understanding, and spiritual connection. Some schools of thought also link it to the Third Eye and the symbolic harmonization of other energy centers.
ZODIAC
There is no consensus regarding Iceland Spar. Some contemporary traditions associate it with Cancer and Aquarius; others consider Clear Calcite compatible with all signs. It is not a traditional birthstone.
