1.09 Ct. Bluish Purple Sapphire from Tanzania

This 1.09 carat oval bluish purple sapphire is an excellent example of balanced gem proportions and considered lapidary work, offered by The Natural Sapphire Company. The gem measures 6.34 x 4.84 x 3.98 mm and presents a transparent body with intense color intensity, a mixed brilliant cut, and an excellent polish, attributes that immediately communicate its high quality. The clarity grade is described as very very slightly included evaluated at eye level, which means the stone appears eye clean to most viewers while preserving natural internal character that confirms its authenticity. The sapphire originates from Tanzania and has been heat treated, a standard and stable enhancement that improves tone and saturation without compromising the natural origin or structural integrity of the crystal. Taken together, the weight, dimensions, color saturation, and finishing work make this oval sapphire a compelling choice for discerning buyers who prioritize both optical performance and well documented provenance.

The mixed brilliant facet design on this oval sapphire is central to its exceptional light performance, geometric faceting that allows maximum light play. A mixed brilliant cut combines a brilliant style crown with a pavilion that uses modified or step facets, the resulting geometry optimizes the balance between return of white light for brilliance and the dispersion of colored light for vividness of hue. The crown facets are configured to catch incoming light and direct it to the pavilion, while the pavilion facet arrangement angles and terminates light in such a way that scintillation and flashes of color are emphasized across movement. The oval outline increases apparent size when set, and the slightly elongated proportions create lively facet interplay across the table and shoulders. The 3.98 mm depth provides sufficient pavilion volume to enhance color saturation, while the careful symmetry and facet alignment minimize light leakage along the girdle, ensuring that the sapphire reads richly colored face up. Excellent polish supports crisp facet junctions, which is a practical necessity for achieving sharp contrast and crisp scintillation, characteristics that educated buyers recognize as indicators of superior lapidary skill.

Clarity and treatment considerations are important to understand for an informed purchase, and this sapphire’s clarity is informative rather than problematic. Very very slightly included evaluated at eye level means that the stone shows only minute inclusions that are generally invisible to the naked eye when viewed face up, inclusions that are typically only apparent under moderate magnification or at an oblique viewing angle. These internal features are consistent with natural sapphires and do not materially affect the gem’s structural integrity or light transmission. Heat treatment, disclosed here, is the most common enhancement applied to sapphires globally, used to encourage improved color uniformity and to refine tone without introducing foreign substances into the crystal structure. The bluish purple hue observed in this stone results from trace elements within the corundum lattice, with combinations of iron, titanium, and vanadium influencing blue to violet shades, and heat treatment often accentuates these interactions to achieve a stable and attractive color. From a practical standpoint, sapphire is a durable gem suitable for everyday wear, and the stability of standard heat treatment means that the color will remain consistent under normal conditions of use.

For the educated buyer seeking value on the basis of technical attributes as well as aesthetic appeal, this Tanzanian oval sapphire presents a compelling combination. The intense color intensity paired with an eye clean appearance and a precision mixed brilliant cut makes the gem suitable as a centerpiece in ring, pendant, or bespoke design, where both face up presence and dynamic light play are desired. The Natural Sapphire Company provides transparent documentation of origin and treatment as part of its standard offering, reflecting provenance practices and gemological disclosure that matter to collectors and ethical consumers. When considering setting options, a low profile bezel will protect the girdle while allowing the oval outline to read larger, and a four or six prong mounting will showcase the pavilion and crown geometry for maximum scintillation. Care is straightforward, with routine cleaning in warm soapy water and the occasional professional check of the setting recommended to maintain the gem’s polished appearance. In summary, this 1.09 carat oval bluish purple sapphire embodies the key qualities educated buyers seek, color, clarity, cut, and documented origin, and represents an investment in a natural, heat treated corundum that will continue to communicate refinement and technical excellence over many years.
