Emerald 1.51 ct – Green, Octagonal Step Cut

Emerald is the green variety of beryl, valued for its rich color, depth, and long-standing cultural significance. Its characteristic green hue ranges from vivid to deep green, often accompanied by natural internal features that are considered an inherent part of the gemstone’s identity.
Chemically composed of beryllium aluminum silicate (Be₃Al₂Si₆O₁₈), emerald crystallizes in the hexagonal crystal system and belongs to the silicate mineral group. In gem-quality material, emerald typically displays a vitreous luster with transparent to translucent clarity.
The refractive index of emerald generally ranges from approximately 1.57 to 1.60, resulting in a restrained brilliance that emphasizes color rather than sparkle. Emeralds are found in several regions worldwide, with notable sources including Colombia, Zambia, Brazil, Afghanistan, and Ethiopia, each associated with distinct visual characteristics.

With a hardness of 7.5 to 8 on the Mohs scale, emerald offers good resistance to scratching; however, its durability is influenced by the presence of natural inclusions, which are common and expected in this gemstone. These internal characteristics can make emerald more sensitive to impact compared to other beryl varieties.
Emerald is well suited for pendants, earrings, and rings with protective settings designed to reduce stress on the stone. While it can be worn regularly with appropriate care, thoughtful setting design and mindful handling are important to preserve its appearance over time.

Emeralds are commonly treated to improve clarity, most often through the use of oils or resins that fill surface-reaching fissures. This practice is widely accepted within the gem trade when properly disclosed and is considered part of standard emerald care.
Any treatments or enhancements are always clearly stated for each individual gemstone. Every stone is professionally examined, and transparent disclosure is regarded as a fundamental part of responsible gemological practice, allowing clients to make informed and confident decisions.
