5.20 Ct. Yellowish Green Cabochon Chrysoberyl from Tanzania

This translucent yellowish green chrysoberyl, available through The Natural Gemstone Company, is a finely presented cabochon weighing 5.20 carat, measuring 10.74 by 8.55 by 5.69 millimeters, and cut to an oval outline that maximizes the gem face and the optical effect. The cutting style is cabochon, a traditional choice for chatoyant stones, and the gem displays a medium color intensity which gives it a clear presence without becoming overpowering. Clarity is graded slightly included when evaluated at eye level, meaning the stone is essentially eye clean to most observers while containing natural inclusions that are common to chrysoberyl and that are in many cases responsible for the characteristic optical phenomena. The polish is excellent, which enhances the surface luster, and the piece is natural with no enhancement, sourced from Tanzania, a well known locality for fine chrysoberyl material.

The most distinctive feature of this stone is the strong cat eye effect, also called chatoyancy, which appears as a bright band of light that traverses the dome of the cabochon when the gem is viewed under a direct light source. Chatoyancy in chrysoberyl is produced by parallel needle like inclusions or fibrous structures within the crystal that reflect light in a single, narrow direction, and when the cutter aligns the cabochon axis with these internal structures the reflection concentrates into a visible band. In this example the band is notably sharp and well centered across the oval dome, creating an attractive linear highlight that moves across the surface as the finger or light source is turned, a quality that collectors and connoisseurs find especially desirable. The cabochon profile and the excellent polish contribute materially to the visibility and definition of the band, because a smooth, high polish surface reduces scattering and allows the internal reflection to be seen clearly against the stone body color.

From a gemological and market perspective, chrysoberyl is prized for a combination of optical interest, durability, and relative rarity in larger sizes with strong chatoyancy, and this 5.20 carat example represents a meaningful size for wearable fine jewelry. Chrysoberyl registers about 8.5 on the Mohs scale of hardness, a value that places it among the harder gem species and assures everyday wearability when set with appropriate care. The slightly included clarity grade should be understood as a natural characteristic rather than a detriment, because the inclusions often contribute to the chatoyancy and thus to the gem character and value. The medium color intensity, together with the translucent to semi translucent body, allows the cat eye band to read clearly while preserving a pleasing internal glow, and the fact that the stone is untreated confirms that the optical effect and color are intrinsic, not manufactured.

When considered for jewelry, the yellowish green hue of this chrysoberyl is unusually versatile, and it complements a broad range of skin tones when set thoughtfully. On warm complexions the golden undertone will harmonize with skin warmth, creating a luminous integration that enhances both the gemstone and the wearer, while on olive and medium brown skin tones the green component brings a fresh, natural contrast that reads as sophisticated and elegant. Fair cooler toned skin will benefit from settings that provide a bit of contrast, such as warm metal tones, because the yellowish green will then appear more vivid against the pale backdrop. For those with neutral undertones the stone will appear balanced and pleasing in a variety of metal choices and design styles. Beyond skin tone, the way the cat eye band runs across the cabochon can be used as a design element, oriented to emphasize length in rings or to align with necklace drops to create dynamic movement as the wearer moves.

At The Natural Gemstone Company we present this gem with accurate measurements and clear imagery so that an informed buyer can assess proportions, color, and the quality of the chatoyancy, and we are available to recommend settings that optimize both security and display of the band. A bezel or partial bezel setting often protects cabochon edges while allowing the band to remain visible, and metal choices such as yellow gold will warm the yellowish green tones while white gold or platinum will add a modern contrast that highlights the clarity of the band. Because this stone is natural and unenhanced, its appearance will remain stable over time, and its hardness supports regular wear in rings, pendants, or statement pieces with appropriate care.
