What You Should Know About Lab Diamonds HPHT

Lab-created stones are significantly cheaper than natural ones due to not needing to be mined from deposits and thus lessening environmental stress.

Make sure that the lab-grown diamond you purchase has been certified by an established gemological lab to ensure you receive a top quality diamond at an acceptable price. You can compare cvd vs hpht.


Laboratory diamonds are physically, chemically, and optically identical to mined diamonds, making them an excellent option for anyone searching for diamonds with similar Color, Cut, Clarity and Carat weight characteristics.

However, they may possess certain traits which make them unsuitable as jewelry pieces; for instance, due to how they were manufactured they may exhibit brown tinting.

In some instances, this brown tint can be lightened or removed using HPHT treatment – an intensive heat and pressure therapy procedure designed to realign crystal structures into a more brilliant, vibrant stone.

This process may also help eliminate or minimize any inclusions present in a diamond, which are imperfections which contribute to its clarity.


Lab diamonds hpht are grown in an enclosed high-pressure, high-temperature chamber (HPHT). This process mimics that used by natural diamonds when created via chemical vapor deposition.

Both methods begin by heating a diamond seed to 800 degrees Celsius before adding carbon-rich gases like methane into a chamber. Over time, the seed begins combining with carbon gases to form layers of diamond.

Clarity grades of diamonds are determined by their internal flaws or inclusions – any tiny flaws such as dark spots, cracks or cloudy areas that exist within its composition.

Inclusions are invisible to the naked eye, so using a microscope to find them can be extremely helpful. A VS1 clarity diamond won’t need one; however a VS2 clarity stone might require 10x magnification for inspection.

Carat Weight

Carat weight of Lab diamonds hpht should also be taken into consideration when selecting an engagement ring; larger diamonds tend to make a bigger statement.

At present, nature-grown diamonds weigh in excess of 400 carats total weight while laboratory-created ones typically top out around 20 carats in weight.

These lab-grown diamonds come in an assortment of different shapes. There are round brilliants and cushion cuts among others.

Each shape offers its own set of advantages. A cushion cut diamond may appear less brilliant than its round brilliant counterpart but still look breathtaking.

Lab-created diamonds come closer to replicating mined diamonds than simulants like Moissanite and Cubic Zirconia in terms of size. Furthermore, their cost per carat is much less than natural diamonds – helping you save money when purchasing an engagement ring.


Lab diamonds offer great value if you’re on a tight budget, often costing 30-40% less than natural mined diamonds of similar size and quality.

However, while they offer substantial cost savings over mined diamonds, their resale values don’t hold up as well in the future. Therefore, if selling is something you plan on doing in the future, mined diamonds might be preferable.

There are various factors that influence the price of a diamond, including its four Cs: color, cut, clarity and carat weight. Of these four characteristics, clarity remains of primary concern when purchasing diamond jewelry.
