Man-made diamonds offer an economical alternative to natural diamonds. Created in a laboratory by carbon-rich gases, these gems offer affordable luxury.
The lab diamonds nz have recently become one of the hottest trends in diamond jewellery. But what exactly are they?
They are a form of carbon
The man made diamonds uk, commonly known as synthetic or lab created diamonds and manufactured diamonds are synthetic carbon diamonds created in a laboratory that are chemically, physically and optically equivalent to mined diamonds.
Natural diamonds are formed deep within the Earth by forging carbon into diamond crystals under extreme pressure and temperature over millions of years, where they undergo transformation under intense pressure and intense temperature.
Diamonds form at an approximate depth of 100 miles in the Earth’s mantle, where heat and pressure increase over time, becoming transform into diamonds which become highly sought-after jewelry items over time.
High Pressure and High Temperature (HPHT) is the preferred technique used to create lab-grown diamonds. To use this process, pure carbon is placed within a metal cube and exposed to intense heat and pressure for months in a machine.
They are created in a laboratory
Man-made diamonds can be produced in the laboratory through two processes; High Pressure-High Temperature (HPHT) and Chemical Vapor Deposition (CVD). Both processes mimic conditions in nature that arise when diamonds form deep within the Earth’s core.
Starting out, the process begins with a small diamond seed being embedded in carbon and placed into a machine for pressure and heat treatment.
After some time has passed, the carbon begins to dissolve and form a diamond around its seed, which can then be cut and polished into gemstone-sized forms.
Lab diamonds do not maintain the same level of value retention that natural diamonds do, meaning they won’t keep their value or trade-in or upgrade easily later if you decide to sell them.
They are more expensive than natural diamonds
People often ask why man made diamonds are more costly than natural ones, and the answer lies within. Simply put, man-made stones require more processing to produce.
One reason is due to natural diamonds’ rarity and demand, taking an inordinately long time and energy-intensive effort to mine them.
Diamond prices depend heavily on carat weight. When considering purchasing a larger diamond carat stone, this factor becomes even more crucial to its cost.
Diamond mining also has a profound effect on the lives of those involved, especially in poor countries where diamonds are an invaluable source of resources.
Laborator-grown diamonds have become more affordable with modern technology allowing up to 40% savings off of natural diamond prices.
They are more durable
Man-made diamonds offer superior durability over natural ones; their hardness rivals that of mined stones tenfold, meaning that they won’t chip or scratch easily.
Laboratory grown diamonds can be created through two distinct processes: HPHT and CVD (chemical vapor deposition). The former emulates how diamonds form beneath earth’s crust by applying high pressure and temperature, pressurizing carbon into crystals at high pressures and temperatures to pressurize their formation into crystals.
But the second method is more cost-effective and uses hydrogen and methane gas mixtures. Microwave power heats a chamber, exciting these gases to form diamond seeds.
These diamonds make a fantastic alternative to natural mined diamonds. Not only are they significantly less costly, but you also have more choices available thanks to their varied shapes and sizes compared to natural mined ones.
