1.87 Ct. Blue Sapphire from Ceylon (Sri Lanka)

One beautifully transparent 1.87 carat cushion shape blue sapphire, measuring 8.35 x 5.84 x 3.96 mm, presents an exceptional combination of geometry and gemological quality. The mixed brilliant cut has been executed to precise proportions to marry the scintillation of brilliant facets with the depth provided by step facet geometry, a design choice that allows maximum light play across the table and through the pavilion. This geometric faceting enhances both brilliance and color saturation, producing lively flashes of blue when viewed face up and a rich internal glow when tilted. The stone displays vivid color intensity and an excellent polish, attributes that increase perceived size and optical impact. Clarity is graded as very slightly included at eye level, indicating small internal characteristics that do not materially impede transparency or sparkle, and in many viewing conditions the sapphire presents as effectively eye clean, a quality prized by discerning collectors.

Origin and treatment influence value and market perception, and this sapphire is sourced from Ceylon Sri Lanka, a region historically renowned for producing richly saturated and lively blue sapphires. Heat treatment is disclosed, a standard and widely accepted enhancement in the trade that stabilizes and intensifies color while preserving structural integrity. For an educated buyer, the combination of Ceylon origin, vivid saturation, robust 1.87 carat weight, and superb cutting geometry represents a compelling value proposition, since these factors together determine both aesthetic appeal and long term desirability. With a hardness of nine on the Mohs scale, sapphire is durable for everyday wear in an engagement ring or a high use pendant, and the excellent polish and well balanced faceting reduce the need for aggressive settings to protect the stone.
