2.45 Ct. Greenish Blue Sapphire from Ceylon (Sri Lanka)

This transparent greenish blue sapphire weighs 2.45 carats and is shaped as a cushion, with measurements of 7.38 x 6.57 x 5.16 mm, and a mixed brilliant cut that balances a broad table with a faceted pavilion. Clarity is graded as eye clean when evaluated at eye level, and the stone exhibits a medium color intensity with excellent polish. The gem originates from Ceylon, Sri Lanka, and has undergone standard heat treatment to enhance color and clarity. The overall presentation is one of measured depth and openness, with the cushion outline providing a softened rectangular silhouette that reads slightly larger for its weight than a round stone of similar caratage, and the mixed brilliant facet arrangement is designed to combine face up color saturation with internal light return.

Under cool natural daylight the sapphire displays its truer greenish blue character, a balanced tone that reads as sea water blue with an evident coolness at the table that allows internal facets to reveal depth and a calm play of light. In direct sunlight the mixed brilliant facets respond with brisk scintillation, producing small flashes of brighter blue as the stone moves, while the pavilion geometry directs lively sparkle back through the table. Under warm incandescent or candlelight the green component becomes more pronounced, and the stone adopts a softer, more muted teal appearance, with a gentle warmth that reduces apparent brilliance but increases the perception of color richness. Under modern white LED lighting the sapphire presents a neutral balance, showing its medium color intensity accurately, and exhibiting crisp facet reflections and a steady distribution of light across the table. Fluorescent lighting can make the blue component seem slightly cooler, and in low ambient light the excellent polish and transparency allow faint flashes and internal reflections to animate the gem without washing out its color. Because sapphires commonly display pleochroic behavior, viewing this stone from different orientations reveals subtle shifts between greener and bluer tones, which are particularly noticeable when the stone is tilted or when the light source moves relative to the gem.

Practical considerations for setting and wear emphasize the stone s natural resilience, its suitability for daily use, and the visual impact of mounting choices. Sapphire is a durable gem with a high hardness that tolerates everyday wear well, and this 2.45 carat cushion will perform reliably as a center stone in ring or pendant applications. An open or minimally obstructive setting will maximize light entry and emphasize the mixed brilliant cut s scintillation and color dynamics, while a low profile bezel can protect the corners of the cushion without significantly reducing light performance when designed with an open gallery. Metal choice will influence perceived color, with warmer metals subtly enhancing the greenish component, and cooler metals emphasizing the blue tones and increasing perceived contrast. The heat treatment applied to this stone is a common and stable enhancement that improves clarity and color, it does not require special maintenance beyond normal jewelry care.
