17.68 Ct. Aquamarine from Brazil

This transparent 17.68 carat aquamarine is presented in a precise emerald cut, measuring 18.27 x 13.69 x 9.71 mm, with an intense blue color, a clarity grade of eye clean when evaluated at eye level, and an excellent polish. The stone is heat treated to enhance and stabilize its color, a standard and permanent treatment for aquamarine, and originates from Brazil. The step facets of the emerald cut emphasize the gem's internal clarity and present broad, even color planes, making this specimen particularly attractive for use as a central stone in rings and pendants. The Natural Gemstone Company offers this piece with clear documentation of its treatment and provenance, reflecting the gemological attributes that matter most to experienced buyers and jewelers.

In terms of durability, aquamarine is a member of the beryl family and has a Mohs hardness of approximately 7.5 to 8, which provides solid resistance to scratches and daily abrasion when set in jewelry. Combined with the gem's excellent polish and thoughtful cutting, this hardness level makes the stone well suited to frequent wear, especially in settings that offer edge protection such as bezels or low profile prongs. Heat treatment applied to this aquamarine is stable and does not adversely affect wearability. For longevity, routine care is straightforward, use warm soapy water and a soft brush to clean, avoid prolonged exposure to strong chemicals or extreme heat, and remove the piece during heavy manual activities that could subject the gem to sharp knocks. For rings intended for everyday wear, a protective setting and periodic inspection by a professional jeweler will minimize risk and preserve the stone's appearance. Overall, the combination of substantial carat weight, robust hardness, excellent polish, and permanent color enhancement makes this emerald cut Brazilian aquamarine a durable and refined choice for daily wearable jewelry, supported by the quality standards of The Natural Gemstone Company.
