0.95 Ct. Greenish Yellow Chrysoberyl from Tanzania

This listing presents a single transparent 0.95 carat Asscher octagon shape chrysoberyl, exhibiting a greenish yellow hue and precise dimensions of 5.07 x 5.07 x 4.52 mm. The gem is fashioned in a traditional Asscher cut that emphasizes step facets and a square outline with softened corners, producing a focused pavilion and a luminous table. The color is described as medium intensity, uniform under standard lighting, and the surface finish is graded excellent for polish. Clarity is recorded as included when evaluated at eye level, reflecting natural internal characteristics that are visible without magnification, and there has been no enhancement or treatment applied to this stone. The material originates from Tanzania, and The Natural Gemstone Company presents it as a naturally occurring, untreated specimen suitable for fine jewelry applications where natural authenticity is a priority.

Chrysoberyl is a gem species valued for a combination of optical performance and durability, and this example benefits from those inherent properties. The material typically exhibits a refractive index that produces lively light return and noticeable brilliance for its size, along with a hardness that ranks high on the mineral scale. The Asscher cut chosen for this piece takes advantage of chrysoberyl strength and clarity to create well defined symmetry and crisp facet reflections, which enhance the stone appearance in direct and diffuse lighting. The included clarity grade indicates internal features that are typical for natural chrysoberyl, and these inclusions do not compromise structural integrity. The excellent polish contributes to clean facet junctions and a refined surface luster, making the gem suitable for daily wear provided it is set with appropriate protection for the corners and table.

The provenance and lack of enhancement are central to the character and value of this chrysoberyl. Mined in Tanzania, the stone carries a geographic signature in its trace element chemistry and growth structure that can be documented and verified by gemological testing. Natural inclusions act as a durable record of formation conditions deep within the host rock, and they are often preferred by collectors and connoisseurs because they confirm natural origin. The absence of heat treatment, irradiation or other common enhancements preserves the original color balance and internal texture of the stone. The Natural Gemstone Company prioritizes transparent sourcing and documentation, and we can provide guidance on independent certification if verification of origin or treatment status is required for appraisal or insurance purposes.

When compared to lab grown counterparts there are distinct differences to consider. Lab grown gems offer consistency of color and fewer visible inclusions at comparable sizes, and they are produced in a controlled environment with predictable outcomes and often at a lower price point. Natural chrysoberyl, as represented by this Tanzanian specimen, offers an individuality that cannot be replicated in a laboratory setting. Each natural stone bears growth features and trace element signatures that record its geological history, and this variability manifests as unique color zoning, inclusion patterns and subtle optical effects. For buyers who value provenance, rarity and the narrative of a naturally formed gem, untreated chrysoberyl provides advantages in terms of collectability and potential long term retention of value. While both natural and lab grown stones share the same basic chemical composition, the natural stone displays a complexity and depth of color and internal character that many buyers prefer, and The Natural Gemstone Company emphasizes those attributes when advising clients on selection.

For practical use and design recommendations this 0.95 carat Asscher chrysoberyl is well suited to classic solitaire settings, three stone treatments or custom bezel designs that protect the girdle and corners. At 5.07 mm across the table it presents a pleasing visual presence on a finger and photographs accurately in both close up and hand shot examples. The medium greenish yellow hue pairs elegantly with yellow gold for tonal harmony, and with white gold or platinum for a contemporary contrast that highlights brilliance. Care should be consistent with high quality gemstones, avoiding strong acids and extreme temperature changes, and routine professional inspections of the setting are recommended to ensure that included features remain secure. Ultrasonic cleaning may be acceptable in many cases owing to chrysoberyl durability, however if inclusions are near surface reaching a professional opinion prior to aggressive cleaning is advisable.
