1.78 Ct. Peach Sapphire from Ceylon (Sri Lanka)

This is a transparent 1.78 carat cushion shape peach sapphire from Ceylon, presented by The Natural Sapphire Company, with precise dimensions of 8.15 by 6.65 by 3.32 millimeters. The gem displays a light color intensity that reads as a delicate peach in daylight and warmer artificial lighting, and it is entirely natural with no enhancement, which preserves original saturation and long term stability. The cutter selected a mixed brilliant cut to combine the optical advantages of both brilliant and step cutting philosophies, and the overall finish is of excellent polish, delivering a surface free of noticeable abrasions or polishing lines. Clarity has been graded as very very slightly included, evaluated at eye level, which indicates inclusions are minor and do not materially interrupt light transmission, allowing the gem to present a clean, luminous appearance to the naked eye.

The geometric faceting strategy of this cushion sapphire is engineered to maximize light play across the table and crown while maintaining an elegant rectangular cushion outline with softened corners. The mixed brilliant arrangement integrates a faceted crown composed of small, well proportioned star and kite facets that radiate from a slightly broad table, feeding light into a pavilion that alternates shallow step facets with small brilliant facets at the pavilion girdle junction. This interplay of facet types produces a balanced combination of brightness and scintillation, with the step facets creating defined contrast zones that enhance color zoning control, and the brilliant facets dispersing light into small, lively flashes. The stone’s crown plane and pavilion facets have been aligned to precise symmetry, minimizing light leakage at the girdle and producing uniform internal reflections across the length and width of the stone. The relatively low profile presents as a shallow pavilion depth relative to the footprint, which increases face up spread and apparent size on the finger while producing expansive zones of consistent brightness. The result is a gem that shows both clean, broad flashes of light and a peppering of small, lively scintillation, qualities that are enhanced by the cushion outline which refracts and redirects light into soft, elegant flashes rather than harsh beams.

From a material quality and setting perspective, the combination of a very very slightly included clarity grade and excellent polish has definitive practical advantages for design and wearability. Inclusions are minor enough to avoid disturbing the optical path at typical viewing distances, so the light path remains largely unobstructed and the mixed faceting can perform at peak efficiency. The absence of enhancement confirms that color and clarity are intrinsic, which is important for clients who prioritize untreated provenance and long term color stability. Origin from Ceylon contributes established gemological context, as Sri Lankan sapphires are renowned for their clean crystals and pastel color palette, attributes that complement the cutter’s decision to favor a mixed brilliant architecture for maximum light performance. For mounting, settings that provide unobstructed light entry through the pavilion and allow the table to sit slightly proud will preserve the geometry optimized by the cutter, and open basket or low bezel designs will emphasize face up spread and scintillation. At The Natural Sapphire Company we can advise on specific setting profiles and metal choices to preserve the stone’s optical advantages, and our specialists will work with you to ensure the faceting geometry and proportion are showcased to achieve maximum light play and enduring brilliance.
