0.92 Ct. Yellowish Green Sapphire from Thailand

This beautiful transparent 0.92 carat oval yellowish green sapphire presents a sophisticated balance of color and form, with measured dimensions of 7.17 x 5.18 x 2.62 mm, and a mixed brilliant cut that optimizes both brilliance and overall face up presence. The hue sits in the yellow green range and is described as intense in color intensity, offering a lively and saturated appearance that is both rare and versatile for fine jewelry. The stone exhibits excellent polish and a clean table, which combined with the mixed brilliant faceting produces lively light return and attractive scintillation across the surface. Originating from Thailand, this sapphire carries the characteristic depth and tonal nuances that collectors and connoisseurs associate with Southeast Asian deposits, and the piece has been heat treated to enhance its color and clarity in a manner that is stable and widely accepted within the trade.

From a gemological perspective the stone is graded as included when evaluated at eye level, a clarity grade that describes visible internal features which do not unduly detract from its beauty but do provide a fingerprint of natural formation. Inclusions are often useful indicators of origin and of the stone's growth history, and in this specimen they interact with the mixed brilliant cut to create a subtle internal character that can be appreciated under magnification and that gives the sapphire identity and provenance. The mixed brilliant cut chosen for this oval shape marries the pavilion facets commonly associated with brilliance to crown facets that flatter color saturation, making the most of the stone's 0.92 carat weight to present an appealing face up area. The measurements of 7.17 by 5.18 by 2.62 millimeters are well proportioned for many traditional and contemporary mounting styles, making the gem a flexible choice for rings, pendants, and bespoke pieces.

Treatment and origin disclosure are essential elements of responsible sales and collecting, and this yellowish green sapphire is heat treated, a standard and stable enhancement used to improve color and reduce the visibility of certain inclusions in corundum. Heat treatment of sapphires is a historically rooted practice that has been studied extensively within gemological laboratories, and when performed appropriately it produces changes that are permanent under normal wearing conditions. Thai sapphires are known for their range of green and yellow tones, and the geological environments of Southeast Asia commonly yield crystals that respond well to controlled heat enhancement. At The Natural Sapphire Company we emphasize transparent disclosure of enhancements and origin information so that educated buyers can make informed decisions, and we provide detailed descriptions that clarify the nature of every treatment and its implications for care and long term stability.

Beyond its technical attributes this yellowish green sapphire resonates with a long heritage of use that gives it added cultural and aesthetic value. Historically sapphires in green and yellow ranges have been associated with vitality, prosperity, and renewal in a variety of traditions, and corundum has served as a protective talisman as well as a symbol of wisdom and steadfastness. In many cultures sapphires were set as signets and devotional gems, and in modern practice the hue and modest size of this stone lend themselves to both classic and contemporary designs that honor those traditions while remaining utterly wearable. For the educated buyer this gem offers a compelling combination of gemological interest, documented origin, and artisanal potential, making it suitable for a discerning collector or for a client seeking a meaningful, enduring gemstone piece. The Natural Sapphire Company is pleased to present this 0.92 carat yellowish green oval sapphire as an example of responsible sourcing and skilled craftsmanship, and we welcome inquiries about matching stones, bespoke settings, and further documentation for this unique gem.
