1.62 Ct. Bluish Green Sapphire from Ceylon (Sri Lanka)

This gemstone is a transparent 1.62 carat trillion shape bluish green sapphire, presented with dimensions of 7.36 by 7.76 by 4.15 millimeters, and a trillion cut that produces a strong, even spread of color across the table. The carat weight of 1.62 carats is a defining attribute of this stone, positioning it in a category that balances presence and practicality. At this weight, the sapphire reads confidently as a focal gem for a wide range of jewelry applications, while retaining proportions that enhance wearability. The measured dimensions indicate a well faceted trillion, with a face up appearance that benefits from both the generous table and the controlled pavilion depth. In practical terms, the 1.62 carat weight translates to a visible and appreciable size on the hand or as a pendant, without the structural and setting challenges sometimes associated with much larger stones.

The trillion cut is a distinctive choice that emphasizes both color and brilliance, and in this example the cut work is executed to maximize optical performance. The sapphire measures 7.36 millimeters along one axis and 7.76 millimeters along the other, producing a balanced triangular outline with well proportioned facets. The depth of 4.15 millimeters yields a depth ratio of approximately fifty five percent relative to the average of length and width, a proportion that supports strong light return while preserving face up size. The excellent polish contributes to crisp facet junctions and unbroken light flow across the surface, increasing apparent clarity and enhancing the jewel like quality of the gem. Because trillion cuts concentrate color toward the center, the vivid color intensity of this stone is presented with both saturation and life, making the bluish green hue read as lively and consistent from a variety of viewing angles.

Clarity was evaluated at eye level and graded very very slightly included, a designation that indicates minimal inclusions when viewed without magnification, and an overall transparency that is effectively clean to the naked eye. This clarity grade preserves both brilliance and durability, since inclusions are small and located so as not to interfere with the structural integrity of the pavilion or crown facets. Importantly, the sapphire is untreated, with no enhancement recorded, which means the color and clarity are natural, as formed. Untreated sapphires with a combination of strong color, transparent body and a meaningful carat weight are relatively uncommon, and the absence of treatment is a key factor in determining both intrinsic value and long term desirability. The gem is identified as originating from Ceylon, Sri Lanka, a source known for producing stones with lively saturation and a characteristic clarity, and this origin aligns with the observed color and optical qualities.

From a practical and design perspective the 1.62 carat trillion bluish green sapphire offers versatility and premium quality. The weight and shape are well suited to a central solitaire in a modern or classic setting, to a three stone design with complementary side accents, or to a bespoke piece where the triangular geometry can be echoed in the mounting. The excellent polish and vivid color intensity ensure that the gem performs as a focal point, while the very very slightly included clarity means that the visual impact is strong without compromising long term robustness. Care recommendations are standard for high quality natural sapphire, including gentle cleaning with mild soap and warm water, avoidance of harsh chemicals and extreme temperature changes, and periodic professional inspection of the setting to ensure secure prongs or bezels. This sapphire exemplifies the standards upheld by The Natural Sapphire Company, combining measured carat weight, natural origin, and superior finish to represent a premium, untreated gem suitable for discerning collectors and designers.
