1.32 Ct. White Sapphire from Ceylon (Sri Lanka)

This heart shaped white sapphire, presented by The Natural Sapphire Company, is a technically refined specimen that balances classical romantic outline with precise lapidary execution, weighing 1.32 carats, with dimensions 6.59 x 7.67 x 3.75 mm. The gem is transparent and colorless, identified as white in its certification, and offers a clarity grade of very slightly included when evaluated at eye level. The cutter employed a mixed brilliant strategy to the faceting, combining a brilliant style crown with a modified pavilion, and executed an excellent polish, resulting in crisp facet junctions and minimal surface abrasion. The stone has undergone heat treatment, a standard and stable enhancement for corundum, and it originates from Ceylon Sri Lanka, a provenance that speaks to a long established gemological tradition and a geological source known for producing material with fine crystalline transparency.

The mixed brilliant heart faceting merges brilliance oriented facet geometry on the crown with pavilion facets arranged to maximize internal reflection while retaining weight in the girdle and pavilion. In practical terms the crown showcases a conventional arrangement of star facets, bezel facets, and upper girdle facets, while the pavilion transitions into a set of mains and lower facets that refract and return light through the crown. A heart outline requires meticulous control of the lobes and cleft, and in this example the lobes are symmetrically proportioned with a clearly defined cleft and a pleasing ratio between length and width, promoting an even scintillation pattern across the surface. The pavilion depth at 3.75 mm relative to the overall length and width produces a balanced pavilion percentage, optimizing return of white light rather than dispersion alone, and the girdle has been calibrated to provide durability for setting without compromising optical performance.

From an optical and physical properties perspective this sapphire adheres to expected corundum parameters, with a refractive index in the range typical for sapphire, and a low dispersion coefficient that yields a clean, white brilliance instead of pronounced spectral flashes. The gem’s very slightly included clarity implies the presence of minor needles or pinpoint crystals that are resolved with magnification but do not detract at normal viewing distances, preserving an overall impression of purity. With a Mohs hardness of nine and a specific gravity consistent with corundum, this white sapphire offers durable wearability for high quality jewelry while maintaining the ability to take a fine polish. The excellent polish noted in the report enhances facet contrast and contributes to crisp light return, and the symmetry of facet placement minimizes light leakage, both of which are critical for a heart shape to perform as a focal stone in a refined setting.

For the discerning collector or jeweler seeking a high end addition the combination of Ceylon origin, controlled mixed brilliant cutting, colorless intensity, and excellent polish position this heart shaped sapphire as both a technical and aesthetic asset. Heat treatment has been applied in a manner consistent with industry standards to stabilize and optimize the stone’s visual characteristics, and the treatment is fully disclosed, ensuring transparency for acquisition and future resale. In a bespoke setting this 1.32 carat heart will read as substantial yet delicate, particularly when mounted in platinum or 18 carat white gold to complement its colorless character, or alternatively in 18 carat yellow gold to create a warm contrast that emphasizes the outline and facet reflections. The Natural Sapphire Company can provide full documentation, high resolution imagery, and consultation on setting options and conservation best practices, ensuring that this precisely cut white sapphire integrates seamlessly into a curated, high end gemstone collection.
