1.25 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This cushion shaped blue sapphire presents a precise combination of size, cut, and origin that is both measurable and meaningful to connoisseurs. The stone weighs 1.25 carat, and its face measurements are 6.40 x 5.93 x 3.96 mm. The cutter has employed a mixed brilliant cut to maximize light return within the cushion outline, and the gem is described as transparent with a light color intensity and an excellent polish. Clarity is recorded as very very slightly included when evaluated at eye level, indicating that the stone appears visually clean in hand while retaining natural crystal characteristics under magnification. The sapphire is heat treated, a stable and commonly accepted enhancement, and its documented origin is Ceylon, Sri Lanka, which contributes to the particular tonal and saturation characteristics observed in this specimen. The Natural Sapphire Company presents this gem with full specification to allow an informed evaluation of its material qualities.

The weight of 1.25 carat is central to the sapphire’s value profile and to its rarity within the market. Moving above the 1 carat threshold creates a perceptible increase in demand, and stones in the 1.00 to 1.50 carat class represent a segment where availability tightens relative to smaller sizes. The additional quarter carat in this piece translates into a larger face up dimension compared with many 1 carat counterparts, enhancing visual presence on the finger or in a pendant without sacrificing proportion or brilliance. Carat weight correlates with material rarity because gem corundum is extracted in irregular crystal sizes, and larger clean parcels yield fewer cuttable gems of premium quality. In practical terms, the 1.25 carat weight places this sapphire in a range that is sought after for personalized fine jewelry commissions and for collectors who value both wearable size and investment resilience, while remaining versatile enough for a variety of mounting styles.

Beyond weight, the stone’s proportions and cut mechanics speak to its optical performance and to how weight contributes to perceived value. The pavilion depth of 3.96 mm relative to the average of the length and width, which is 6.165 mm, results in an overall depth percentage of approximately 64.2 percent, a proportion that supports good light return and balance between brightness and color face up. The mixed brilliant facet arrangement in a cushion shape is intended to distribute scintillation while preserving the integrity of the stone’s light color intensity, producing a lively, slightly airy blue that is characteristic of fine Ceylon sapphires. The very very slightly included clarity grade at eye level confirms that the gem presents a clean window to the eye, with only minor internal features that do not detract from face up appeal and that typically remain invisible without magnification. The excellent polish further enhances surface reflection, contributing to sparkle and to a refined finish when set.

Taken together, the 1.25 carat weight, the measured proportions, the mixed brilliant cushion cut, the eye level clarity, and the Ceylon origin create a sapphire that combines rarity and practical beauty. The weight elevates the stone’s market position relative to smaller examples, while the documented gemological attributes support confident placement in a bespoke engagement ring or an elegant solitaire setting. Heat treatment, noted as the enhancement, aligns with standard trade practice and offers a stable, long lasting improvement to tone and saturation. For those seeking a sapphire with a clear specification and a balance of presence and refinement, The Natural Sapphire Company provides this gem with full transparency on its dimensions and characteristics, enabling precise selection or appraisal based on weight driven rarity and overall gem quality.
