1.59 Ct. Grey Sapphire from Ceylon (Sri Lanka)

One beautiful transparent 1.59 carat round shape grey sapphire, measuring 6.40 by 6.37 by 5.40 mm, offers a balance of presence and wearability that is well suited to bespoke jewelry. The stone is fashioned in a mixed brilliant cut, a cutting style that pairs a brilliant facet arrangement on the crown with a modified pavilion to enhance scintillation while maintaining efficient weight retention. At this size the precise facet alignment and excellent polish deliver consistent light return, producing crisp flashes and a subtle dispersion that complements the stone s faint grey color intensity. Clarity is graded as very very slightly included when evaluated at eye level, meaning the sapphire reads effectively eye clean in typical mounting positions, and its transparency allows fine faceting to remain visually impactful without competing surface blemishes. The sapphire is unenhanced, retaining its natural state and structural integrity, and it is reported to originate from Ceylon Sri Lanka, a provenance noted for producing sapphires with refined color and desirable crystal quality.

The round shape and the 6.40 by 6.37 mm footprint make this sapphire exceptionally adaptable for custom design projects. In a solitaire ring the stone will sit with a clear and classical presence, while in halo or three stone compositions it provides a stable and symmetrical center that simplifies design proportions and setting geometry. The mixed brilliant cut supports both prong and bezel settings, as the crown facets create lively top side brilliance and the pavilion depth of 5.40 mm contributes to secure seatings in lower profile and raised head styles alike. For pendant and stud earring applications the stone s weight and dimensions produce an elegant scale that reads as refined rather than oversized, and the faint grey hue offers a versatile neutral that pairs well with white diamonds or colored accent stones. Because the sapphire presents as effectively eye clean, designers can plan close set details or open gallery work without concern for prominent inclusions, and the lack of enhancement assures consistent long term appearance and ease of maintenance.

For clients seeking a responsibly sourced and gemologically transparent choice for custom work, The Natural Sapphire Company can facilitate design development from initial concept through finished setting.

The natural, unenhanced nature of this Ceylon sapphire favors daily wear, and simple care guidelines such as periodic cleaning with mild detergent and a soft brush and routine professional checks will preserve polish and mounting security.
