1.29 Ct. Yellowish Green Sapphire from Tanzania

This oval yellowish green sapphire weighs 1.29 carats, and measures 7.13 by 5.36 by 3.86 millimeters. The gem is transparent, and it has been fashioned in an elegant mixed brilliant cut that balances faceted sparkle with smooth, reflective planes. The color presents as a yellowish green with an intense color intensity that remains even across the table and pavilion. Clarity is graded as slightly included when evaluated at eye level, with natural internal features that are modest in size and distribution. The polish is excellent, yielding crisp facet junctions and a refined surface finish. This sapphire is natural and untreated, with no enhancement, and it originates from Tanzania, a source known for producing a wide spectrum of sapphire hues.

The mixed brilliant cut employed in this stone enhances its optical performance, producing distinct scintillation and a pleasing interplay of light and color. The oval proportions create an attractive length to width ratio of approximately one point three three, which gives the stone a graceful presence in most settings without appearing elongated. The depth measures 3.86 millimeters, which corresponds to an overall depth of approximately sixty one point eight percent relative to the average diameter, a proportion that contributes to both saturated color and efficient light return. Because the sapphire is transparent, the cut interacts with the material to deliver lively flashes and a steady body color, allowing the intense yellowish green to be read clearly from the table while subtle tonal variations appear at different angles, adding complexity without diminishing legibility.

Clarity characteristics are described as slightly included at the eye level, and these inclusions are natural to the crystal growth process. They do not compromise the gem s structural integrity, and they can be regarded as identifiers of a genuinely natural gem. The absence of any enhancement is an important attribute, as it confirms that the color and clarity are intrinsic to the sapphire rather than the result of heat or chemical treatment. Origin information indicates Tanzania, and while each deposit has its own geological history, this stone s combination of color, tone, and clarity reflects the natural variability that collectors and connoisseurs appreciate. With a hardness of nine on the Mohs scale, sapphire ranks among the hardest gem materials used in jewelry, and the excellent polish on this piece will help maintain surface luster with normal wear.

Over time this sapphire s natural beauty will continue to captivate because its desirable physical attributes are inherent rather than induced. The intense hue is a function of the gem s internal composition, and it is not dependent on surface coatings or transient treatments that can fade or require replacement. The well-executed mixed brilliant cut and the excellent polish will preserve the stone s ability to return light and exhibit sparkle, and the general toughness of sapphire ensures resistance to abrasion and scratching under ordinary conditions. To retain peak appearance, routine care such as gentle cleaning with warm soapy water and a soft brush is recommended, and periodic professional inspection will ensure that the setting remains secure. At The Natural Sapphire Company we document the provenance and treatment status of our stones, and we can advise on setting styles that both highlight the yellowish green tone and protect the gem from sharp impacts. This sapphire s natural color, precise cutting, and uncompromised condition make it a lasting choice that will remain visually engaging for many years.
