1.21 Ct. Yellowish Green Chrysoberyl from Tanzania

This is a beautifully transparent 1.21 carat yellowish green chrysoberyl, precision cut into a classic emerald shape, with exact dimensions of 6.33 x 5.22 x 3.99 mm. The gem has been evaluated as eye clean at standard viewing distance, displaying intense color intensity and an excellent polish that enhances facet definition and light return. There has been no enhancement, the gem is untreated, and its origin is documented as Tanzania, a locality known for producing high quality chrysoberyl crystals. The emerald cut was chosen to emphasize the stone clarity and to create broad step facets that produce a refined hall of mirrors effect, which allows the intense yellowish green hue to show uniform, while minimizing the appearance of any internal zoning that can occur in some stones.

From a gemological perspective this chrysoberyl combines several properties that make it stand out to an educated buyer, beginning with its refractive behavior and its physical durability. Chrysoberyl typically has a refractive index in the range 1.746 to 1.755 and a dispersion of approximately 0.014, with a Mohs hardness of about 8.5. Those numbers mean that while chrysoberyl does not produce the high fire seen in diamond, it returns light with a strong, adamantine sparkle and stable, lively brilliance that is noticeably different from more common green gems. Compared to peridot, which typically has a lower refractive index and a softer hardness, this chrysoberyl offers superior brilliance and far greater wearability for everyday jewelry. Compared to green sapphire, which can approach similar hardness but normally exhibits different optical character, chrysoberyl provides a distinct tone and a slightly different light return due to its unique refractive index and facet interaction. Against diamond, chrysoberyl shows less dispersion, therefore less colorful fire, but it compensates with intense body color and a crisp, bright luster that makes the yellowish green hue vivid and attractive in both natural and artificial lighting.

For the discerning buyer, the value proposition is clear and multifaceted. The combination of natural, untreated origin, eye clean clarity, intense color, excellent polish, and a tailored emerald cut delivers a gemstone that is both collectible and ready for fine jewelry setting. Stones of this weight and dimensions present an optimal face up presence for rings and pendants, where the emerald cut will read as elegant and understated, while still making a confident color statement. The lack of any treatment increases both immediate aesthetic appeal and long term market desirability, because untreated gems from reputable sources like Tanzania command stronger collector interest and typically lower long term risk relative to heat treated or otherwise enhanced material. The structural toughness and hardness of chrysoberyl also make it an intelligent choice for daily wear, because it resists scratching far better than many green gemstones, preserving polish and facet crispness over years of use.

At The Natural Gemstone Company we curate gemstones that meet demanding quality criteria, and this Tanzanian chrysoberyl exemplifies that standard. Its eye clean clarity simplifies design choices for jewelers, because the stone does not require heavy bezel work to mask inclusions, and its intense yellowish green color permits elegant metal pairings in warm yellow gold or in more modern rose gold and platinum as a cool contrast. For buyers focused on investment quality, this piece offers transparency of origin, documented untreated status, and the kind of durability and optical appeal that supports continued desirability. If you are seeking a gemstone that combines a refined emerald cut silhouette, substantial face up color, and the practical advantages of a hard, high luster gem, this 1.21 carat Tanzanian chrysoberyl represents a distinctive and sensible acquisition, backed by The Natural Gemstone Company assurance of authenticity and careful selection.
