Size might be a significant factor to consider when selecting a diamond. Small, medium and large-sized lab-grown diamonds are available. How much bigger can a lab-grown diamond become for those who want a bit more?
The technique of lab-growing diamonds provides countless alternatives if you’re inclined to big stones. We must first discuss the various procedures for generating lab diamonds to answer this issue.

THE PROCESS OF MAKING LAB-GROWN DIAMOND
Innovative devices created specifically for creating diamonds may be seen within a diamond lab. With one very significant exception: lab-grown diamonds grow incredibly quickly. Technology advancements have made it possible to produce diamonds in a manner that perfectly mimics the conditions under which mined diamonds develop.
Diamonds created in laboratories start as seeds of carbon. Carbon seeds are transformed into stunning diamonds in a lab, just like seedlings grow into blossoms in a greenhouse. The carbon eventually crystallises into a spectacular diamond under prolonged, extreme pressure and temperature.
How long does a lab-grown diamond take to grow? Just a few weeks. Although the methods are essentially the same, the size of a diamond will naturally depend on how long it takes to develop. The end product is a remarkable diamond brimming with fire, brightness, and scintillation.
The High-Pressure High-Temperature Method(HPHT)
Diamonds can only form naturally under environmental circumstances that must reproduce. It would help if you used a belt press, split-sphere press, or cubic press to create an environment favourable for the formation of diamonds. You can apply both of the following due to the size of each of these mechanical presses: Extreme Pressure and the second one is high temperature.
The hydraulic press uses these two circumstances to turn carbon into a diamond seed. A specific crystal structure starts to develop when extremely high heat (approximately 2000°F) and high pressure (about 1.5 million pounds per square inch) are introduced.
The hydraulic press transforms carbon into a diamond seed using these two conditions. When extremely high heat (about 2000°F) and tremendous pressure (roughly 1.5 million pounds per square inch) are added, a crystal structure begins to take shape.
This exact and regulated environment permits the seed to be the substrate onto which the carbon lattice builds. Crystal layers join together throughout the growing process, melting away the carbon. Finally, cooling transforms the diamond seed into a crystal carbon structure.
Chemical Vapor Deposition, a more widely used approach, generates an atmosphere ideal for forming diamonds, whereas this process does the same (CVD).
DO LARGE DIAMONDS GROW LONGER THAN SMALL OR MEDIUM DIAMONDS?
In contrast to the millions of years required for diamonds to originate in the ground, growing a diamond in a lab often only takes a few weeks. Naturally, the length of time depends on the particular growth method employed.
HPHT painstakingly grows a diamond under intense pressure. The pressure must change as the diamond gets bigger to keep the diamond’s growth under control. Think about squeezing a little stone to get an idea of this notion. Not too challenging, I presume? Let’s say the pebble was now a vast boulder. Would you be able to press it with the exact level of force, or would you need to exert more pressure when using a second hand?
It takes careful planning to develop a diamond to a considerable size. The method can, fortunately, be accommodated in a lab. Large diamonds need more time and skill than tiny to medium-sized ones, which may form in only a few weeks.
However, it is undoubtedly feasible and provides a wide range of possibilities for selecting the size of your lab-grown diamond.
