Lab Grown Diamonds – The Process Of Making It

A Symbol Of Love And Commitment

We all know diamonds can accentuate our whole look from dull to glam within seconds. But not everyone can afford to buy this luxurious piece of stone. Thus, Lab grown diamonds are the new fashion in the market. It does not matter when you buy earrings, an engagement ring, or a bridal set, the lab grown diamonds studded in your metal will give you a never-seen aura. Bhanderi Lab provides you with the best lab diamonds to express your love and commitment most exuberantly and romantically possible!

Since the 1800s, diamonds have been mined from the earth. The popularity and charm of diamonds have been popular for many generations. However, no rational person could have imagined that it would be possible to grow diamonds in labs. Diamonds grown in labs are ethically and morally sound. Also, with the improvement in technology and development, lab diamonds have homogenous features and attributes like naturally mined diamonds. Thus, they are indistinguishable when viewed by the naked eye. In the mid-1900s, diamonds were first grown in labs for industrial purposes. The attributes such as thermal conductivity and hardness of lab grown diamonds were ideal for use in industries.

Lab grown diamonds are replicas of naturally extracted diamonds except for their origin. They both consist of pure carbon and have high durability and transparency. But man made diamonds are more cost-effective and will not put a dent in your budget. Thus, you can now have the charm and grace of wearing a diamond without emptying your wallet. Diamonds grown in Labs and naturally extracted diamonds are graded in the same manner by some of the popular grading institutions of the world.

Process Of Making Lab Grown Diamonds

Due to the advent of technology and advancements, there are two primary methods of making the best Lab Grown Diamonds.

Diamond Creation Using HPHT Method

The earliest known method of growing diamonds in labs is the High Pressure High Temperature method. The process of HPHT replicates the growing process of natural diamonds forming inside the crust of the earth. After 1950, the process of HPHT started producing high-quality Lab Grown Diamonds. HPHT process amplifies and enhances the hue of man made diamonds to make them colorless, pink, green, blue, or yellow.

The process of HPHT starts with a diamond seed. The diamond seed, composed of metals and powders, is a highly refined graphite carbon and a catalyst. Naturally, mined diamonds are too made of the same constituents. The diamond seed is then put inside the HPHT chamber in the center. The seed put inside the chamber is subjected to maximum heat and pressure, much like natural diamonds are formed. The maximum heat and pressure subjected to the diamond seed are 2000 degrees Fahrenheit and pressure of about 1.5 million PSI (pounds per square inch). When the diamond seed is subjected to such extreme temperature and pressure, its carbon starts melting. The melting of carbon changes the atomic structure, and thus diamonds form circling the seed.

Press Designs Used In HPHT Process

Three press designs are used to make Lab Grown Diamonds using the HPHT process. Diamond powder for industrial uses is made by using a Cubic Press. A belt press can grow many diamonds in Labs in a single cycle. It is very large consisting of two anvils that press together to produce the necessary pressure to make Lab Grown Diamonds. The Belt Press is also commonly used to grow diamonds for industrial purposes. Currently, the Bars Press is the most efficient tool to grow high-quality diamonds in Labs. The Bars Press possesses a mixture of inner and outer anvils to put hydraulic pressure on the growth cell.

Diamond Creation Using The CVD Process

The CVD process, which stands for Carbon Vapor Deposition, was developed in the 1980s and is comparatively a newer method of growing diamonds in Labs. The CVD method of making diamonds replicates the process of growing diamonds in interstellar gas clouds. The CVD method of making Lab Grown diamonds uses comparatively less pressure than HPHT and uses smaller machines.

A diamond seed is put inside a vacuum chamber in the Carbon Vapor Deposition process. The vacuum chamber is heated to nearly 1500 degrees Fahrenheit after filling with gases rich in carbon. The gas that is rich in carbon inside the chamber transforms into plasma due to the application of extremely high temperatures. The carbon-rich gas that turned into plasma releases pieces of carbon. The pieces of carbon shower down on the diamond seed, and thus the seed grows.

Lab Grown Diamonds: Which Process Is Better?

Both the process of growing diamonds in Labs have their pros and cons. However, you do not have to worry about choosing between HPHT and CVD Diamonds. Just like naturally mined diamonds, the aura and magnificence of Lab Grown Diamonds come from their physical attributes. The exact method employed to grow diamonds in labs does not matter.

The 4C's of Diamond cut, clarity, color, and carat is used to grade and price Lab Grown Diamonds. Diamonds created either through HPHT or CVD are any day more affordable and budget-friendly than what we will get by mining from the earth. Not to mention, Lab made Diamonds are conflict-free and sustainable too!

Many names are given to CVD diamonds – Lab made diamonds, Man made diamonds, or Cultured diamonds. Nevertheless, what you call them, they have certainly created a spur in the diamond industry. With the rapid increase in its market share, it will slowly capture the whole of the industry!
