Sapphires — the mesmerizing blue gemstones that have long been symbols of success, prosperity, and prestige. From rings and necklaces to earrings, bangles, and pendants, sapphire jewelry has always been coveted worldwide. Among these treasures, one story stands out: the tale of Khun Sumanee’s extraordinary Ceylon sapphire pendant — a piece so rare and valuable that Cartier itself once tried to buy it back.
Who Is Khun Sumanee?
Known in Thai society as the “Thai Barbie,” Khun Sumanee Kunakasem is the daughter of Police Major General Pramote and Khunying Supatra Jongcharoen. Belonging to one of Thailand’s most prominent families, she is recognized for her elegance, wealth, and impeccable taste — her assets are said to be worth billions. But beyond her high-society status, it’s her dazzling jewelry collection that often makes headlines.

The History of the Pendant
The pendant in question was acquired by Khun Sumanee at a Christie’s auction in Geneva, a global stage for rare and precious gems. Crafted in the 1930s, this pendant has a history spanning nearly a century. Its centerpiece is a remarkable Ceylon sapphire sourced from Sri Lanka — famed for producing some of the world’s most vivid and valuable sapphires.
What makes it extraordinary?
-
Size: Weighing over 180 carats, its scale alone is breathtaking.
-
Color: A rich, velvety blue with brilliance and life — the rarest shade among sapphires.
-
Cut: Expertly fashioned into a pear shape, enhancing both sparkle and elegance.
-
Natural beauty: Most sapphires undergo heating to improve color, but this one is completely unheated — a true miracle of nature.
So extraordinary is this pendant that Cartier — the very house that created it nearly a century ago — contacted Khun Sumanee in hopes of buying it back. With such rarity and beauty, its value is considered priceless.
A Jewel Fit for a Legend
This pendant is more than jewelry; it’s a legacy, an artwork, and a testament to the unmatched beauty of natural sapphires. And while only a few in the world may ever own a stone of this magnitude, the story reflects the timeless allure of sapphires as symbols of grace and achievement.
