1.92 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This sapphire is a transparent, cushion shaped gem weighing 1.92 carats, with dimensions of 8.13 x 6.18 x 3.89 mm. It has been cut in a mixed brilliant style, combining a faceting scheme designed to balance color saturation with light return. The color is described as vivid, and the stone exhibits an excellent polish that contributes to its overall brilliance and luster. Clarity is graded as very slightly included when evaluated at eye level, indicating minor internal characteristics that do not materially detract from the gem's visual transparency. The stone has undergone heat treatment, a widely accepted and stable enhancement in the trade, and is offered through The Natural Sapphire Company, where documentation of the stone's key attributes accompanies the gem.

The proportions of this cushion sapphire have been considered to optimize both face up appearance and depth driven color. With a table oriented for mixed brilliant faceting and a depth of 3.89 mm, the proportion yields an overall depth ratio of approximately 54 percent, a balance that allows the vivid blue to remain saturated without appearing overly dark or windowed. The mixed brilliant cut places a series of smaller brilliant facets on the crown and modified step or brilliant facets on the pavilion, which enhances scintillation while preserving the stone's body color. The excellent polish ensures crisp facet junctions and minimal surface disturbances, which in turn improve light performance and the perception of clarity. The very slightly included clarity grade reflects inclusions that are minor and stable, commonly accepted in natural sapphires, and these inclusions are not visible at a normal viewing distance when the gem is set in jewelry.

The provenance of this sapphire is Ceylon, Sri Lanka, a source with a long and well documented history of producing high quality blue sapphires. Sri Lankan material is frequently sought for its combination of vivid saturation and a lively, open tone, attributes that can be traced to the island's unique metamorphic geology and gem bearing alluvial deposits. Origin contributes to value in several measurable ways, including market preference for certain color profiles associated with Ceylon material, the historical and cultural recognition of Sri Lankan sapphires among collectors, and the added assurance of traceability when provenance is documented. Within the marketplace, Ceylon origin is often associated with sapphires that display a distinct blend of brilliance and saturated blue, characteristics that this 1.92 carat stone demonstrates. The Natural Sapphire Company notes and records origin as part of its appraisal and sourcing procedures, which supports informed decision making by customers and by retailers.

Heat treatment has been applied to enhance the stone's color and overall appearance, a controlled and permanent process under normal wearing conditions that is common practice for natural sapphire material from Sri Lanka and other sources. This enhancement improves color uniformity and can reduce the visual impact of certain inclusions, while preserving the natural character and structural stability of the corundum. For setting and care, standard precautions apply, such as avoiding exposure to harsh chemicals and extreme temperature change during jewelry repair or resizing, and advising routine professional cleaning to maintain polish and brilliance. Given its dimensions and face up size, the sapphire presents as a substantial yet wearable center gem for engagement rings, a refined focal element for a pendant, or a distinctive component in bespoke pieces where a vivid Ceylon blue is desired. The Natural Sapphire Company can provide further technical documentation and recommendations for mounting and design to ensure the stone is set in a manner that optimizes its color, durability, and visual impact.
