1.51 Ct. Greenish Yellow Sapphire from Thailand

From the moment this sapphire was born deep within Thailand’s ancient metamorphic rock, it carried a quiet story of heat and pressure that shaped its character, color, and clarity. Miners and cutters who work with these stones passed it through careful hands, selecting this particular crystal for its beautiful transparency and its rare greenish yellow hue, and at The Natural Sapphire Company we honored that origin by stabilizing and enhancing its natural beauty through controlled heat treatment. The result is one transparent 1.51 carat oval shape greenish yellow sapphire, measuring 8.30 x 5.89 x 3.07 mm, cut to a mixed brilliant pattern that balances scintillation with depth, polished to an excellent finish, and graded with a clarity of slightly included, evaluated at eye level. Its intense color intensity and the precision of the mixed brilliant cut create a lively play of light, while subtle internal features attest to its natural formation and authentic provenance from Thailand. Worn alone it feels singular and storied, carried from geological time into a modern setting that respects its journey.

For jewelry designers and customers looking for a stone ideal for custom work, this oval offers exceptional flexibility and character, and its proportions and 1.51 carat weight make it particularly adaptable to rings, elongated pendants, and elegant three-stone or halo compositions. The 8.30 by 5.89 mm table and 3.07 mm depth suit both prong and bezel settings, and the mixed brilliant cut concentrates light for finger-facing brilliance, while the oval outline flatters and visually lengthens, creating a refined silhouette in any metal. Designers can use the intense greenish yellow to pair with warm yellow gold for glowing harmony, with rose gold for vintage romanticism, or with platinum for a contemporary contrast that emphasizes its green notes. Slight inclusions add individuality without distracting from the gem’s visual impact, and the excellent polish ensures smooth settings and secure mountings. At The Natural Sapphire Company we see this sapphire as a storyteller and a centerpiece, ready to become a bespoke jewel that reflects personal taste, cultural resonance, and a lineage that began in Thailand and culminates in your custom creation.
