5.44 Ct. Blue Sapphire from Thailand

This transparent 5.44 carat cushion shape blue sapphire measures 10.63 x 10.18 x 5.69 mm, with a mixed brilliant cut that marries a faceted crown of brilliant style facets to a pavilion that balances scintillation with depth, producing lively return and controlled windowing. The cutter has maintained excellent symmetry and an excellent polish, resulting in crisp facet junctions and clean light paths, while the pavilion depth is proportioned to approximately 54.7 percent of the average diameter, optimizing internal reflection for maximum brilliance. Clarity is graded very slightly included when evaluated at eye level, indicating only discreet internal characteristics that do not detract from face up performance, and the stone exhibits vivid color intensity with strong, saturated blue tones that read both rich and lustrous under standard viewing conditions. Origin is Thailand, and the sapphire has been heat treated, a stable and widely accepted enhancement that improves color uniformity and saturation while preserving the stone's structural integrity.

Compared to lab grown sapphires, this natural Thai sapphire carries attributes that discerning buyers prize, including geographic provenance, natural trace element zoning, and unique inclusion patterns that act as a microscopic fingerprint of origin and formation environment, qualities that laboratory growth cannot replicate authentically. While lab grown material can offer very high clarity and consistent color at lower cost, natural stones retain inherent rarity and collector value, and often exhibit the nuanced interaction of light and color that derives from natural crystal growth and subtle facet to inclusion relationships. Heat treatment has been fully disclosed to ensure transparent trade practices, and The Natural Sapphire Company provides documented provenance and gemological reporting to corroborate natural origin and enhancement status. For connoisseurs who value long term desirability, resale potential, and the singular story embedded in a natural gem, this vivid, well executed cushion sapphire represents a technically refined choice that combines precision cutting, fine polish, and classic Thai color chemistry.
