9.37 Ct. Emerald from Colombia

This transparent Colombian emerald, offered by The Natural Emerald Company, is a cushion shape weighing 9.37 carats, with measurements of 13.51 x 13.17 x 8.76 mm, and a mixed brilliant cut. The stone exhibits a vivid color intensity and an excellent polish, with clarity graded as very slightly included when evaluated at eye level. Enhancement is standard, consistent with reputable emerald treatments that stabilize and improve appearance. The proportions and facet structure of the mixed brilliant cut optimize light return while maintaining a robust pavilion depth, which contributes to overall integrity when set in jewelry.

Emeralds are beryl family gemstones with a Mohs hardness of approximately 7.5 to 8, and this specimen combines that baseline hardness with careful cutting and finishing to make it well suited for regular wear. The cushion profile and the substantial depth of 8.76 mm provide a strong profile that resists edge chipping when the gem is properly secured. Standard enhancement, applied in a controlled manner, helps to fill surface-reaching fissures and reduce stress concentrations, improving toughness compared with an untreated example of similar clarity. For daily wear longevity it is advisable to employ protective mounting styles, such as a bezel or guarded prong setting, that shield the girdle and corners from direct impact, and to avoid prolonged exposure to harsh chemicals and extreme heat. Routine maintenance recommended by The Natural Emerald Company includes gentle cleaning with warm soapy water and a soft brush, periodic inspection of the setting to ensure secure prongs, and professional servicing for any reapplication of enhancement if needed. Ultrasonic and steam cleaners are generally not recommended for emeralds that have received standard enhancement, because aggressive cleaning methods can affect the stability of the treatment. With prudent setting choices and basic care, this Colombian cushion emerald presents an excellent balance of beauty and practical durability, making it a refined option for daily wear in rings, pendants, or other fine jewelry.
