1.51 Ct. Pink Sapphire from Ceylon (Sri Lanka)

This 1.51 carat transparent pink sapphire presents in a precisely executed trillion shape, with measured dimensions of 6.99 millimeters by 6.89 millimeters by 3.67 millimeters. The stone is cut as a triangular brilliant, calibrated to yield balanced light return and scintillation across the three apexes. Color is classified as medium intense, exhibiting a lively pink saturation that reads consistently face up under standard daylight balanced viewing. Clarity is described as very very slightly included when evaluated at eye level, indicating minute internal features that do not materially detract from transparency or brilliance under normal viewing conditions. The pavilion and crown were brought to an excellent polish, which enhances facet contrast and maximizes the apparent clean window to the interior. This sapphire was heat treated as a standard and stable enhancement, and the material is sourced from Ceylon Sri Lanka, with provenance and handling documented by The Natural Sapphire Company.

From a proportions perspective the trillion form of this stone is noteworthy for its near equilateral plan, with side measurements that differ by only one hundredth of a millimeter, supporting symmetrical facet alignment. Using the averaged diameter of 6.94 millimeters, the measured depth of 3.67 millimeters produces a depth percentage of approximately 52.9 percent, a value that sits within an optimal range for triangular brilliants where a slightly shallower pavilion can preserve weight while maintaining return of light. The facet architecture is consistent with a triangular brilliant philosophy, where a modified crown matrix paired with a faceted pavilion creates both broad flash and tight scintillation. Facet junctions are crisp, and the girdle appears even, allowing for predictable behavior during setting without unexpected light leakage or asymmetrical windowing. The cutting achieves a pleasing balance between fire and brightness, so that dispersion and white light return remain in equilibrium when the gem is viewed at varied angles.

The clarity remark of very very slightly included at eye level describes inclusions that remain subtle to the unaided eye, and that are typically visible only under magnification or specific viewing orientations. Because these inclusions are minor, the overall transparency is excellent, allowing the medium intense pink to read with saturation rather than becoming clouded or dulled. Heat treatment has been employed to optimize hue uniformity and to reduce silk and certain color zoning that are common in natural Ceylon sapphires, and the result is a stable color presentation that is well suited to fine jewelry usage. The pink tone in this sapphire is driven primarily by trace chromium substitution within the corundum lattice, and the material shows the characteristic dichroic response when rotated under polarized light, a diagnostic feature that gemmologists use to confirm natural corundum identity. Hardness and toughness inherent to sapphire make this stone suitable for everyday wear, and the combination of medium intense color, high polish, and limited inclusions yields exceptional versatility for designers aiming for either a refined solitaire or a delicate halo configuration.

The journey from mine to market for this Ceylon pink sapphire follows a series of controlled and traceable steps, beginning in the alluvial and hard rock operations of Sri Lanka where skilled miners recover gem rough. Initial sorting separates material by hue and clarity, with high quality pink rough moved to specialist workshops for preforming. Preforming establishes the triangular outline and removes unwanted weight from corners and pits, then the detailed facet plan is executed by a cutter experienced with triangular brilliants, who adjusts pavilion angles and table proportions to achieve the calculated depth percentage and desired light performance. After cutting the piece undergoes heat treatment in monitored furnaces to enhance color tone and remove residual silk, followed by a polishing regime that culminates in the excellent surface finish documented here. The Natural Sapphire Company performs final quality control, photographic documentation, and provenance verification, applying consistent standards to ensure that the stone delivered to the client matches the technical description. For mounting recommendations the trillion outline and moderate weight lend themselves to three prong heads with low crowns when the intent is to maximize visible color, or to a bezel with open gallery when protective settings are preferred, and the stone also pairs well with accent diamonds that support and amplify the pink saturation rather than overpower it.
