Brazilian Emerald 6.24 Carat (6.86 Ratti) – Panna Stone

Natural Brazilian Emerald (Sapota Panna) – 6.24 Carat (6.86 Ratti) Octagon Step Cut

This Natural Brazilian Emerald (Sapota Panna) weighs exactly 6.24 Carats (6.86 Ratti) with calibrated dimensions of 13 x 9 x 6 mm. Expertly faceted into a balanced Octagon Step Cut, this Earth-mined gemstone displays a vibrant green saturation, vitreous luster, and the diagnostic natural internal inclusions that authenticate genuine natural beryl.

Mineralogical Identity & Physical Constants: Emerald is the prestigious green variety of Natural Beryl (beryllium aluminum cyclosilicate, Be₃Al₂(SiO₃)₆), colored by trace amounts of chromium (Cr³⁺) and vanadium (V³⁺) substituting within the crystal lattice. Ranking at Mohs hardness 7.5 to 8.0, it exhibits a refractive index of 1.570 to 1.585 (birefringence ~0.006–0.007, uniaxial negative), a specific gravity of 2.68 to 2.72, and a diagnostic hexagonal crystal system. Natural emeralds characteristically feature microscopic fluid inclusions, two-phase bubbles, and delicate growth patterns historically referred to in lapidary arts as the jardin (French for garden), which serve as unmistakable proof of natural Earth formation.

Geographical Origin & Lapidary Profile: Sourced from the prolific granitic pegmatite deposits of Minas Gerais and Bahia, Brazil, this gemstone is known in the Indian lapidary trade as Sapota Panna. It features a lively, warm yellowish-green color reminiscent of fresh sapota foliage, making it a sought-after commercial variety for astrological wearing and classic jewelry. This stone is 100% natural, unheated, and untreated with dyes or artificial resins.

Cultural Legacy & Traditional Wearing: Known in Sanskrit as Marakata and universally in Indian tradition as Panna (पन्ना), emerald is the primary gemstone associated with Mercury (Budh / बुध). In classical Vedic traditions, it is customarily set in Yellow Gold, Panchdhatu, or Sterling Silver for rings and pendants, traditionally worn on the little finger (Kanisthika) of the working hand on Wednesday mornings during Shukla Paksha.

Care Instructions

• Never use ultrasonic or steam cleaners: Natural emeralds feature internal microscopic fissures (the natural jardin) that can be compromised by ultrasonic vibrations or thermal steam shock.
• Clean gently using lukewarm water, a mild dish soap solution, and a very soft camel-hair brush or microfiber cloth. Rinse thoroughly and pat dry.
• Avoid exposure to harsh household acids, bleaches, acetone, and sudden extreme temperature fluctuations.
• Store individually in a padded gemstone pouch or jewel box to avoid abrasion from harder gems such as corundum (sapphires/rubies) and diamonds.
