1.33 Ct. Greenish Blue Sapphire from Madagascar

This beautiful transparent 1.33 carat princess shape greenish blue sapphire measures 5.88 by 5.48 by 3.36 millimeters, and offers a precise combination of size, shape, and color that is rare in an untreated stone. The gem displays a medium color intensity that reads as a delicate greenish blue in daylight and under warm light, and the princess cut presents a lively face up that maximizes both brilliance and the stone s apparent surface area. The clarity is graded as very slightly included when evaluated at eye level, which means that minor natural features are present but do not detract from the gem s visual appeal when set. The polish is excellent, providing sharp facet junctions and crisp light return, and importantly this sapphire has received no enhancement, preserving its natural color and structure. Sourced from Madagascar, a region known for producing a wide range of attractive sapphires, this stone is an excellent specimen for buyers seeking a natural, untreated gem with clean presentation and controlled color.

From a gemological perspective the sapphire is corundum, with trace elements such as titanium and iron responsible for the greenish blue hue that makes this piece distinctive. The medium color intensity indicates a balance where saturation is sufficient to convey rich tone without becoming dark, and the princess cut has been executed to present an even spread of color across the table while creating dynamic flashes from the pavilion. Very slightly included at eye level indicates that inclusions are minor, typically fine crystals or thin needle like features and perhaps tiny pinpoint crystals that are visible only upon careful inspection and do not interrupt light transmission in any meaningful way. The excellent polish enhances the gem s ability to perform optically, helping facets meet precisely so that light is reflected efficiently and the stone appears lively on the finger or in a pendant. For an educated buyer the untreated status is particularly meaningful, because it confirms the color and clarity are natural rather than the result of heat or other treatments that can change value and long term permanence.

Durability is one of the most important practical considerations when choosing a gemstone for daily wear, and corundum is exceptionally well suited to everyday jewelry. Sapphires rate nine on the Mohs scale of hardness, second only to diamond, which makes them highly resistant to scratching from common environmental sources such as metal edges, glass, and most household items. The crystalline structure of corundum gives it good toughness and the absence of true cleavage means it does not split easily along internal planes. Those qualities, combined with the compact dimensions of this princess cut, make the gem robust for rings, bracelets, and pendants intended for frequent use. To optimize long term durability I recommend protective settings such as a bezel or a low profile four prong mount with secure crowns, especially for rings where edges can be subject to impact. A halo or channel setting can also protect the corners of the princess cut while enhancing perceived size and adding accent stones.

Care and mounting guidance will help ensure that this sapphire remains attractive for years to come. Routine cleaning with warm soapy water and a soft brush is safe and effective, and a quick rinse and dry will restore brilliance after everyday wear. Avoid harsh chemicals and prolonged exposure to strong acids or bases, and exercise caution with ultrasonic and steam cleaners if there are any sub surface fissures, although the very slightly included clarity and lack of enhancement suggest normal ultrasonic cleaning will usually be safe. For a ring designed for daily wear consider a bezel or secure prong design, and for a pendant or earrings a bezel or closed gallery will reduce the risk of hooking or lateral impact. Because this sapphire is untreated and originates from Madagascar its natural color is stable, and the lack of enhancements adds to both its durability and its investment quality for collectors and buyers who prefer untreated stones.

For an educated buyer this 1.33 carat princess shape greenish blue sapphire represents a compelling balance of aesthetic appeal, gemological integrity, and wearable durability. The combination of natural color, very slightly included clarity at eye level, excellent polish, and Madagascar origin makes it a notable addition to a bespoke engagement ring or a refined everyday piece.
