1.77 Ct. Blue Cabochon Sapphire from Ceylon (Sri Lanka)

One beautiful translucent 1.77 carat pear shape blue sapphire is presented here, with precise dimensions of 7.46 by 5.78 by 4.05 millimeters, rendered in a classic cabochon cut, clarity graded as included evaluated at eye level, color intensity graded as intense, and an excellent polish. The sapphire originates from Ceylon Sri Lanka, and it has been heat treated, a standard enhancement that improves color uniformity and stability. At first glance the gem shows a deep, saturated blue with a pleasing translucency that allows inner depth and soft light play without full transparency. The pear outline lends a graceful, slightly elongated silhouette that suits both traditional and contemporary settings, and the cabochon profile emphasizes smooth, glowing color rather than faceted brilliance. The weight of 1.77 carats is well matched to the stated dimensions, producing a gem that is substantial enough for a focal setting while remaining comfortable for everyday wear when properly mounted.

Understanding the clarity and color characteristics is essential for an educated buyer, and the included clarity grade evaluated at eye level requires careful explanation. Included means that internal features are present and visible without magnification under normal viewing conditions, a common and expected condition for many natural sapphires. In cabochon cut stones, inclusions often appear as soft wisps or slightly translucent areas rather than sharp crystals, and these features can contribute to the character and origin identification of the stone. For Ceylon sapphires in particular, a fine silk or slightly fibrous texture is sometimes present, and this can diffuse light in an appealing way that enhances perceived color. The intense color intensity noted for this piece describes a strong saturation with good tone that is neither too dark nor too light, an important balance because color is the single most influential factor in sapphire value. Heat treatment has been applied to stabilize and enhance the color, which is a widely accepted and permanent enhancement in the trade, and The Natural Sapphire Company fully discloses this treatment to maintain transparency and buyer confidence.

The cabochon cut and the exceptional polish deserve focused attention, because cut style and finish determine how a sapphire will present once set. Cabochon cutting involves shaping and smoothing the stone to a domed top and a flat or slightly rounded base, a technique that showcases color and translucency while minimizing the visibility of surface reaching inclusions. The pear form is less commonly seen in cabochon sapphires than in faceted stones, which makes this example particularly interesting for collectors and designers seeking a distinctive silhouette. The dimensions produce a balanced table and depth relationship, with the 4.05 millimeter height providing sufficient thickness to retain durability, especially given sapphire hardness. An excellent polish means the surface has been finished with precision to produce a high luster and minimal abrasions, which enhances the gem s ability to reflect light and present a clean, silky face. Compared with faceted stones that sparkle with internal reflections, cabochons offer a serene, saturated appearance that reads as luxurious and organic, well suited for bezel settings that protect the girdle and emphasize the stone s smooth contours.

From an investment and wearability standpoint this sapphire offers a clear proposition to a knowledgeable buyer, and provenance coupled with disclosure increases its appeal. Ceylon Sri Lanka has a storied history as a source of fine blue sapphires, known for producing stones with lively blue tones and a luminous character. The heat treatment applied here is a stable enhancement that brings out the best in a sapphire without undermining durability, and The Natural Sapphire Company s documentation and responsible sourcing practices help ensure traceability and ethical conduct. Sapphire rates nine on the Mohs hardness scale, which translates to excellent resistance to scratching and suitability for daily wear in rings, pendants, and other jewelry when set with appropriate protection. For care, avoid harsh chemicals and ultrasonic cleaning if the setting is delicate, and periodic professional inspection will keep the mounting secure. For buyers seeking a gemstone with both aesthetic presence and enduring value, this 1.77 carat Ceylon cabochon combines intense color, classic pear form, and a polished finish that will perform beautifully in either a bespoke commission or a refined ready made setting, and our team at The Natural Sapphire Company is available to provide additional imagery, certification options, and design guidance to ensure the piece meets exacting expectations.
