What ARE
Lab-Grown Diamonds are diamonds grown in highly controlled laboratory environments using advanced technological processes that duplicate the conditions under which diamonds naturally develop when they form in the mantle, beneath the Earth’s crust. Since they are made of the same material as naturally mined diamonds, they exhibit the same optical and chemical properties

Are Lab Grown
Lab-Grown Diamonds have the same chemical, physical and optical properties as natural diamonds. They are real diamonds with the same crystal structure and beautiful sparkle, as well as the same hardness. They are also just as durable as natural diamonds. Lab-Grown Diamonds are created in highly controlled laboratory environments using advanced technological processes that duplicate the conditions under which diamonds naturally develop when they form in the mantle, beneath the Earth’s crust. These lab-created diamonds consist of actual carbon atoms arranged in the characteristic diamond crystal structure just like natural diamonds.

The diamond carat weight measures how much a diamond weighs. A metric “carat” is definedas 200 milligrams. Each carat is subdivided into 100 ‘points.’ The diamond price increases withdiamond carat weight because larger diamonds are rarer and thus they are more desirable. Twodiamonds of equal carat weight can have very different values and prices depending on threeother factors of the diamond 4Cs.
02
A diamond’s cut is often thought of as a shape (round, heart, oval, marquise, pear), however,what a diamond cut actually does means how well a diamond’s facets interact with light.Precise artistry and workmanship are required to fashion a stone so its proportions, symmetry,and polish deliver the magnificent return of light only possible in a diamond. Achieving the bestcut for a diamond reflects in the stone’s final beauty and value.
03
Crystal clear is the way to go. A completely colorless diamond is chemically pure.The diamond color evaluation of most diamonds is based on the absence of color. A chemicallypure and structurally perfect diamond has no hue and is of a higher value. Many of thediamond color distinctions are so subtle that they are invisible to the untrained eye; however,these distinctions make a very big difference in diamond quality and price. Structurally sound, and very rare. Generally. D-F will be colorless to naked eye, While G-J may be slightly distinguishable to a very trained eye.

Diamonds can have internal characteristics known as inclusions or external characteristics known as blemishes. Evaluating diamond clarity involves determining the number, size, relief, nature, and position of these characteristics, as well as how these affect the overall appearance of the stone. Many inclusions and blemishes are too tiny to be seen by anyone other than a trained diamond grader. This is why expert and accurate assessment of diamond clarity isextremely important.
Frequently Asked
Lab-Grown Diamonds are diamonds grown in highly controlled laboratory environments using advanced technological processes that duplicate the conditions under which diamonds naturally develop when they form in the mantle, beneath the Earth’s crust.
Since they are made of the same material as naturally mined diamonds, they exhibit the same optical and chemical properties.
The Lab Grown diamonds are created with the same chemical compositions as Natural diamonds. The controlled temperature and pressures allow the diamond seed to form the same characteristics as Natural Mined Diamonds. The Diamonds are judged based on 4 C’s i.e Carat, Color, Clarity, and Cut. LGDs are graded on the same criteria as mined diamonds, by the same independent gemological laboratories that grade earth-extracted diamonds.Unlike the billions of years it takes to create mined diamonds, lab-grown diamonds typically take 2-8 weeks togrow, depending upon the size of a diamond. White diamonds take the longest time to grow, taking about 2-3 weeks to grow a 1-carat diamond.
The process of making lab-grown begins with a seed. The diamond seed is used for both the processes of creating a lab-grown diamond – CVD and HPHT.
Chemical Vapor Deposition or CVD involves placing the seed in a plasma reactor chamber which has a mix of carbon-rich gases added at low pressures. Microwaves are inserted into the chamber and superheated into a plasma. This creates the optimum conditions for the carbon to deposit on the diamond seed. An ionization process takes place and the diamond seed begins to grow.
High Pressure High Temperature or HPHT involves placing a diamond seed in a carbon medium with a catalyst. Carbon is the building block of all diamonds whether earth mined or made in a lab. High temperature and high pressure are then applied like when a diamond grows in the earth’s core. This deposits the carbon on the diamond seed and makes it grow.
While the pricing of Natural Diamonds is determined primarily by the 4C’s, the lab-grown diamonds have more uniform pricing. As the production of lab-grown diamonds is unlimited, they are priced significantly lower than natural diamonds.
Socioeconomic Conscious Luxury - One of the major benefits of lab-grown diamonds is that you know exactly where the diamond originated. These diamonds are sustainable and have a minimal environmental impact. They are not associated with child labor, conflict, or environmental destruction.
Beauty & Durability - These diamonds have the same physical, chemical, and optical properties as mined diamonds.
Value & Quality - These diamonds offer excellent value and are more affordable than mined diamonds with no compromise on size or quality.
No, lab-grown diamonds are diamonds. Diamond simulants on the other hand are gemstones that may look like diamonds but are made up of different materials and do not have the same durability or brilliance.
