The Difference Between HPHT Treated Natural and Lab-Grown Diamonds

1. The Difference Between HPHT Treated Natural and Lab- Grown Diamonds Did you know 65% of the world’s rough diamonds come from Africa? But with the help of modern technologies and advanced techniques, we have started producing diamonds in labs quickly, which used to take billions of years! Today, you can buy a range of natural to lab-grown to treated diamonds. So, if you want to purchase a diamond, it’s important to understand the difference between an HPHT (High Pressure, High Temperature) diamond and an HPHT-treated natural diamond. What are HPHT Diamonds? As you might know, natural diamonds were formed billions of years ago, around 150 km beneath the Earth’s surface! However, HPHT diamonds are generally lab-grown diamonds but mimic the same conditions necessary for diamond growth found in nature.

2. To create a diamond using the HPHT method, a diamond seed is placed in a large press that produces pressures exceeding 870,000 pounds per square inch at temperatures ranging from 1300-1600°C. At such high pressures and extreme temperatures, a high-purity carbon source dissolves molten metallic flux, allowing carbon atoms to crystallize around the seed, forming a rough lab-grown diamond. After that, this diamond is cut and polished, ready to use in jewellery. What are HPHT Treated Natural Diamonds? It was the year 1990 when a group of scientists began experimenting with HPHT equipment to change the colour of diamonds, leading to the development of high-pressure, high-temperature colour treatment. Natural diamonds that undergo the process of enhancing their colour are called HPHT-treated diamonds. With the help of this treatment, brownish or yellowish diamonds can be turned permanently into colourless stones or fancy-coloured gems. An HPHT-treated diamond is perfect for those buying natural diamonds at a lower cost. How do you check whether a diamond is lab-grown or has been HPHT treated? Since the HPHT method is inexpensive, it is most commonly used commercially. Lab-grown diamond companies are required to disclose whether your diamond is HPHT lab-grown or HPHT treated. However, it is almost impossible for a normal person to identify the difference between an HPHT lab-grown diamond and an HPHT-treated diamond. However, trained gemologists can identify the difference between the two with the help of advanced instruments. Then, there are GIA-approved certified laboratories that provide detailed reports mentioning the diamond treatments. So, if you are unsure whether your diamond is HPHT lab-grown or HPHT-treated, you can send your diamond to a reputable lab for grading and verification.
