0.53 Ct. Bluish Green Sapphire from Madagascar

This 0.53 carat, round shape, bluish green sapphire is a fine example of color, clarity, and craftsmanship, presented by The Natural Sapphire Company. The stone measures approximately 4.43 by 4.37 by 3.55 millimeters, and it is transparent with a medium intense color intensity. The gem has been fashioned in a mixed brilliant cut, and it carries a clarity grade of very slightly included, evaluated at eye level. The polish on this sapphire is excellent, producing crisp facet junctions and a clean surface finish. The sapphire has been heat treated, a common and stable enhancement for this species, and its origin is Madagascar, a source known for producing a wide range of attractive sapphire hues. These objective specifications are intended to provide an educated buyer with the key factors that determine both aesthetic appeal and market value.

Clarity and polish are two interrelated attributes that influence a sapphire of this size more than many buyers might expect. A clarity grade of very slightly included, evaluated at eye level, indicates that the stone presents minimal internal features to the unaided eye, and that any inclusions do not materially distract from the overall visual performance. At 0.53 carat and with transparent body color, the sapphire benefits from good light transmission, so even small inclusions can be less apparent when the cut and polish are optimized. The excellent polish ensures that facet surfaces are smooth and reflective, increasing both brilliance and perceived depth. For a buyer who values longevity and daily wearability, it is useful to note that sapphire is a corundum mineral with a high hardness, which combined with excellent polish and careful setting will deliver durable performance for many years.

The mixed brilliant cut is a deliberate choice to balance color saturation, light return, and scintillation in a small round stone. This style typically combines a brilliant faceted crown with a modified pavilion, creating a play of broad flashes and lively sparkles that complement the bluish green tone. In this sapphire, the cut proportions were executed to maximize internal reflection and to distribute color evenly across the girdle, while preserving the apparent size and presence on the finger. Well executed mixed brilliant cutting refines the way light enters through the table and crown, disperses within the crown and pavilion facets, and then exits as return light that the eye perceives as brightness and fire. Precision in facet angles and symmetry is especially important in a 4.43 by 4.37 by 3.55 millimeter gem, because small deviations can alter light performance significantly. The excellent polish further enhances facet crispness, which translates to sharper contrast and more defined flashes when the stone is viewed in motion.

For the discerning buyer, this Madagascar bluish green sapphire represents a considered combination of attributes that drive value, namely transparent clarity, appealing medium intense color, careful cutting, and responsible disclosure of heat treatment. Madagascar is recognized for producing sapphires with a variety of hues, and origin information can influence desirability among collectors and designers who favor provenance as part of a gem narrative. Heat treatment is a stable and widely accepted enhancement when fully disclosed, and it is noted here to ensure full transparency. The Natural Sapphire Company stands behind accurate descriptions and can provide additional close up imaging, certificate grade reports, or assistance with setting recommendations. For jewelry design, a four prong or low bezel setting will showcase the round mixed brilliant cut while protecting the girdle in day to day wear. Cleaning can be done with warm soapy water and a soft brush, and professional ultrasonic cleaning is generally acceptable for heat treated sapphires, although one should seek our guidance for any piece with complex settings or accompanying gems. This sapphire is an excellent choice for a refined engagement ring, a custom pair of earrings, or a pendant that emphasizes unique color, and our gem specialists are available to discuss matching stones, mounting options, and certification to ensure that your acquisition aligns with your aesthetic and investment priorities.
