3.69 Ct. Yellowish Green Chrysoberyl from Tanzania

One beautiful transparent 3.69 carat emerald cut yellowish green chrysoberyl is presented by The Natural Gemstone Company, this stone measures 9.86 by 7.55 by 4.83 millimeters, and it displays a classic emerald cut that emphasizes linear facets and a broad table, the color intensity is light with a fresh yellowish green tone that reads as lively and elegant in daylight, clarity is graded as slightly included when evaluated at eye level which means the stone appears clean to the unaided eye while retaining natural internal features that confirm its identity, polish is excellent which enhances the facet brightness and overall presence, enhancement is none and the material is natural chrysoberyl originating from Tanzania, this combination of weight, cut, untreated status and origin makes the piece both attractive for wearable jewelry and interesting to collectors who value natural provenance.

From a gemological perspective this chrysoberyl presents a compelling balance of optical performance and durability, chrysoberyl is a member of the beryllium aluminum oxide family and is noted for a high refractive index and strong adamantine to subadamantine luster, the stone has a hardness of approximately eight and a half on the Mohs scale which means it resists daily wear much better than many other green gemstones while still being readily faceted into precise shapes, the emerald cut on this specimen is an excellent choice for a gem with slightly included clarity because the broad facets accentuate color and clarity while minimizing the visibility of small natural inclusions, the excellent polish speaks to the lapidary skill applied to this rough, it ensures superior light return from the pavilion and crown which in turn gives the stone a lively internal glow and crisp facet contrast.

When comparing the brilliance and visual behavior of this chrysoberyl to more commonly known gemstones it is useful to contrast refractive indices and dispersion values, chrysoberyl typically has a refractive index in the range of about 1.745 to 1.754 and a modest dispersion around 0.014, by comparison diamond has a much higher refractive index and dispersion which produces pronounced fire and scintillation, diamond dispersion is approximately 0.044, this means diamonds exhibit stronger spectral flashes under white light, however chrysoberyl compensates with a strong surface luster and efficient light transmission, the result is a gem that reads as bright and lively without the strong colored flashes of diamond, comparing to sapphire which has a refractive index slightly higher than chrysoberyl but a similar low dispersion, sapphires are known for deep saturated colors while chrysoberyl offers a unique clarity and crystalline brightness in lighter green tones, relative to peridot which often shows a warmer yellow green and higher dispersion but lower refractive index, this chrysoberyl will appear crisper and more refractively lively, in short the stone stands out because it combines a crystalline, gemmy transparency with a high surface luster and durable structure, qualities that educated buyers recognize as signatures of a fine collectible gem.

For the discerning buyer this piece from The Natural Gemstone Company represents an opportunity to acquire a natural, untreated chrysoberyl with excellent lapidary qualities and documented origin, the slightly included clarity grade means the gem presents as eye clean which preserves both everyday appeal and resale desirability, the emerald cut provides an elegant, architectural shape that sits beautifully in classic solitaire rings and bespoke pendant settings where the broad table will showcase the pale yellowish green color, the durable hardness makes it suitable for ring wearers who want a green gemstone that will withstand regular use better than many alternative green stones, provenance from Tanzania adds a layer of interest because collectors and connoisseurs often prize stones with clear mining origins, finally the absence of enhancement simplifies long term care and valuation, The Natural Gemstone Company stands behind the description and offers additional detailed imagery and gemological documentation on request, for those seeking a green gemstone that balances rarity, durability and refined optical charm this 3.69 carat emerald cut chrysoberyl is an excellent candidate.
