Certified HPHT Diamonds
At Kesh Gemstone, we believe in one core principle: authenticity is everything.
Every diamond we use is not only earth-mined — it’s also enhanced using the HPHT (High Pressure High Temperature) process to bring out its natural brilliance, clarity, and color.
And to prove it, we back every stone with trusted third-party certification for complete peace of mind.
🧬 WHAT IS HPHT?
HPHT stands for High Pressure High Temperature — a treatment that mimics the earth's natural forces to brighten and clarify natural diamonds.
This process transforms lower-color diamonds (like yellow or brown tones) into G-H or better grades, making them whiter, brighter, and visually stunning.
✨ The result?
You get a more beautiful diamond, with the same durability, chemical makeup, and sparkle — at a fraction of the price of untreated equivalents.
