The Rarity of HPHT-Treated Natural Diamonds
HPHT-treated natural diamonds are incredibly rare and captivating, offering unique beauty while preserving their authenticity. High-Pressure High-Temperature (HPHT) treatment enhances the color and brilliance of diamonds, but finding these stones-especially in larger sizes-is extremely uncommon.
Limited Availability of Suitable Rough
Only diamonds of exceptional quality qualify for HPHT treatment. These diamonds must be Type Ila, containing minimal nitrogen and possessing a perfect crystalline structure.
Type Ila diamonds make up less than 2% of all mined diamonds, making them exceptionally rare.
A Highly Selective Process
HPHT treatment is used to improve color, often transforming brownish diamonds into colorless gems or creating fancy colors like yellow, green, pink, or blue. However, HPHT does not improve clarity, as it cannot reduce inclusions or imperfections in the diamond.
Only diamonds with the right structural integrity can undergo the treatment without compromising their beauty, making the supply even more limited.
The Challenge of Large HPHT-Treated Diamonds
Most large natural diamonds are left untreated because they already have significant value. Finding a larger HPHT-treated diamond is exceptionally rare, as the treatment is reserved for carefully selected stones. This makes the market for these diamonds smaller than that of traditional untreated stones.
Certified and Fully Disclosed
HPHT-treated diamonds come with full disclosure and certification, ensuring transparency about their origin and enhancement. Unlike lab-grown diamonds, these are 100% natural, having formed over millions of years before being enhanced through advanced technology.
A Rare and Stunning Treasure
For those seeking a diamond that stands out—one that is as unique as their love story-an HPHT-treated natural diamond is an extraordinary choice. With their rarity, enhanced brilliance, and natural origins, they offer the best of both worlds: the beauty of nature with the refinement of expert craftsmanship.
Owning an HPHT-treated natural diamond means possessing something few others have. It's a piece that tells a story of rarity, resilience, and radiance—a true treasure meant to be cherished for a lifetime and beyond.
