1.43 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This stone is a transparent oval blue sapphire weighing 1.43 carats, with precise dimensions of 7.23 by 5.79 by 4.11 millimeters. The mixed brilliant cut combines a faceted crown with a faceted pavilion to optimize both face up brilliance and internal light performance. Clarity is graded as very slightly included, evaluated at eye level, indicating the presence of minor internal features that do not detract from the gem when viewed without magnification. The sapphire exhibits a light color intensity characteristic of classical Ceylon origin, and the excellent polish enhances surface luster and the overall crispness of facet junctions. The proportions yield a depth of approximately 63 percent based on the average diameter, a proportion that supports lively light return while maintaining a pleasing face up appearance for its carat weight.

Carat weight plays a central role in the rarity and market value of sapphires, and a 1.43 carat example occupies a notable position in the supply curve. Gemstone pricing typically increases on a non linear basis as stones move beyond common weight bands, with each increment above one carat representing a reduction in available supply and frequently an increase in price per carat. At 1.43 carats this sapphire offers a meaningful presence that reads larger on the finger than many sub one carat stones, while remaining in a weight range that is more readily sourced than much larger stones. The given dimensions translate to a generous face up area relative to the weight, so visual impact and wearability are both strong attributes. For buyers who prioritize a balance between visible size and long term market desirability, this weight is especially attractive because it signals scarcity relative to smaller material, while retaining versatility for a variety of jewelry settings.

Origin and treatment are important factors in valuation and long term performance, and this sapphire is from Ceylon Sri Lanka and has been heat treated, a standard and widely accepted enhancement that stabilizes and improves color without materially affecting durability. Ceylon sapphires are esteemed for their typically lighter and more pastel blue hues, and provenance contributes to both aesthetic expectation and collector interest. The mixed brilliant cut and excellent polish support strong scintillation and return of light, enhancing the perception of color and brilliance in daily wear. The combination of a well proportioned 1.43 carat weight, transparent clarity at eye level, reliable heat treatment, and Sri Lankan origin produces a stone that is both rare in supply and practical for fine jewelry use.
