10.88 Carat Natural Thai Yellow Sapphire – Rectangle Cut, IDI Certified

Ten carats of golden yellow corundum from Thailand's historic Old Bangkok mines. This isn't the pale, washed-out yellow you sometimes see in lower-grade material—this is the kind of saturated, buttery color that made Thai sapphires famous. At 10.88 carats, this represents what serious collectors and jewelers seek: substantial size, rich color, and the quality that comes from one of the world's most respected sapphire origins.

Old Bangkok's Legacy

Thailand's Old Bangkok mining region produced some of the world's finest yellow sapphires before the deposits were largely exhausted. The geological conditions there created corundum with a distinctive golden yellow tone—warmer and richer than the lemon yellows from other origins. This piece has been gently heated, a traditional enhancement used for centuries to optimize the color already present in the rough. It's not creating something artificial; it's revealing the stone's full potential. In the international gem trade, heated Bangkok sapphires are valued and sold at premium prices precisely because the treatment is stable, permanent, and brings out the stone's inherent beauty without compromising its structure.

Size Meets Quality

The rectangle faceted cut at 14.81 × 10.55 × 7.20 mm isn't just about aesthetics—it's about maximizing the stone's natural color while maintaining the depth needed for brilliance. The good clarity means you're looking into the gem, not at surface-level inclusions. Light travels through, interacts with that golden color, and exits with the kind of glow that only well-formed corundum can produce. At 11.85 ratti, this falls well into the range where astrological practitioners and jewelry designers both take notice.

Jupiter's Golden Stone

In Vedic astrology, yellow sapphire is Pukhraj, the gemstone of Jupiter (Guru). Jupiter governs wisdom, prosperity, and spiritual growth. For astrological use, the key requirements are substantial weight, good clarity, and rich color—all of which this stone delivers. While some practitioners insist on completely untreated material, many accept traditional heat treatment as it doesn't alter the stone's fundamental nature. Certified by DGLA, this meets the traditional requirements for serious astrological use from one of the world's most respected sapphire origins.

What Makes This Sapphire Stand Out:

• 10.88 carats—substantial size in quality material
• Old Bangkok origin—historic Thai mining region
• Golden yellow color—warm, saturated tone
• Good clarity—transparent with natural character
• Traditional heat treatment—standard enhancement for color optimization
• Rectangle faceted cut—modern geometry, maximum color
• DGLA certified—documented authenticity and treatment disclosure
• 14.81mm length—substantial presence

This is for the buyer who understands the gem trade. Heat treatment in Bangkok sapphires isn't a compromise—it's a traditional practice that's been refining these stones for centuries, and the international market values them accordingly. Whether you're designing a major jewelry piece, need a Jupiter remedy that meets traditional standards, or simply want a Thai sapphire that represents the origin at its finest, this delivers on every level.

Perfect for: Statement rings and pendants, Vedic astrology (Pukhraj for Jupiter/Guru), serious gemstone collections, investment portfolios, or anyone who wants premium Thai sapphire with proper certification and international market credibility.
