0.69 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This sapphire is a fine example of classic Ceylon material, presented as a transparent 0.69 carat oval measuring 6.26 x 4.29 x 2.77 mm. The gem has been fashioned in a mixed brilliant cut that balances a faceted crown for lively brilliance with a well proportioned pavilion for light return. The clarity is described as very very slightly included when evaluated at eye level, which means the inclusions are minimal and do not interrupt the gem face up when worn. Color intensity is rated as intense, and the polish is excellent, creating a surface finish that maximizes sparkle and depth. Enhancement by heat treatment has been applied, a standard and stable practice in sapphire trade that refines color and reduces certain inclusions, resulting in an attractive, enduring gem that will perform beautifully in jewelry.

From a gemological perspective this stone displays the qualities that educated buyers prize. The Ceylon origin is significant, as sapphires from Sri Lanka are historically renowned for their clear, vivid blues with a luminous quality that reads bright and lively in daylight. The intense color intensity in this example sits at a desirable intersection of saturation and tone, offering a rich blue without appearing too dark, which makes the stone versatile for many settings. The mixed brilliant cut enhances face up brightness while preserving weight and maximizing visual performance in a smaller carat class. Very very slightly included clarity at eye level is a strong selling point, because clean looking sapphires with intense color and excellent polish are relatively scarce, especially in gem sizes that are practical for rings and pendants.

Practical considerations for design and wear also favor this sapphire. Corundum is a 9 on the Mohs hardness scale, second in toughness only to diamond among common gem materials, which means this stone is very well suited to daily wear in an engagement ring, or as a signature pendant or pair of studs. The dimensions of 6.26 by 4.29 by 2.77 mm indicate a comfortable oval that translates to elegant proportions on a finger or necklace. The mixed brilliant cut will deliver lively flashes and scintillation, and the excellent polish helps resist surface wear while enhancing luster. For mounting suggestions, a secure bezel or four to six prong setting in platinum or 18 karat gold will protect the girdle while highlighting the blue tone, and a delicate halo of small diamonds will amplify perceived size and brilliance for a more dramatic presentation. For an educated buyer concerned with value retention, the combination of Ceylon origin, intense color, scarce clean appearance at eye level, and careful cutting and finishing make this stone an appealing balance of beauty and rarity.

As a gift this sapphire will make a striking and meaningful choice, designed to convey elegance, thoughtfulness, and enduring quality. Whether given for an engagement, an anniversary, a milestone birthday, or simply as a personal expression of appreciation, the deep yet lively blue signals loyalty and timelessness, traits that resonate for special occasions. At The Natural Sapphire Company we prioritize accurate description and responsible sourcing, and we can provide further information on provenance and available documentation upon request. Heat treatment is disclosed up front because transparency is important to informed collectors and gift buyers, and because heat treatment in Sri Lankan material is a well established, permanent enhancement that remains widely accepted in the market. If desired, this sapphire can be set into a bespoke piece to match the recipient style, with design counsel available to recommend settings that protect the gem and present its color to best effect. For those seeking a memorable gift that combines gemological merit with emotional significance, this 0.69 carat Ceylon blue sapphire offers a refined and trustworthy option.
