Throughout its history, lab diamonds have been somewhat of a mystery. Shrouded in awe and brilliance, not only are lab diamonds are viable alternative to natural diamonds that are built upon the foundations of sustainability and ethical sourcing but lab diamonds come in a wide array of selections, from the brightest cuts to unique colors, and various shapes. There’s a lab diamond for everyone.
This article will cover 4 crucial historical aspects of lab-grown diamonds from a historical context. Should there be any questions, concerns, or need assistance to buy Rare Carat, kindly contact Rare Carat Diamonds customer care and a representative will respond soonest.
Lab-Grown Diamonds Historical Periods
The Origin of Lab-Grown Diamonds: Revolutionary Discovered by GE Researchers
It was the 19th century, post-industrial revolution. The world was going through multiple periods from the Roaring Twenties, World Wars, Jazz Age, Civil Rights Movement, Student Movement, Cold War, Space Age, Information Age, and so much more. During this period, scientists discovered that diamonds were made out of pure carbon.
They pondered if it was possible to replicate or even imitate the natural high pressures and high-temperature conditions that diamonds were exposed to. They were subjected to every kind of carbon source extreme conditions using various methods such as explosives, flames, hydraulic presses, and electric arcs from coal, oil, graphite, and even organic matter all to no avail.
It was until the 1950s that General Electric, who were looking to develop their industrial prowess through the use of synthetic diamonds, discovered that by compressing and heating a mixture of metal and graphite catalysts by a belt press, of a temperature of over 3,600 Fahrenheit (2,000 Celsius) and 1 million+ atmospheres, that they were able to create the very first synthetic diamond in 1954 successfully.
How Synthetic Diamonds Are Created in Laboratory
- HPHT (High Pressure, High Temperature): in essence, it is the successor to General Electric’s original method, but instead of just a belt pressure. Now, it uses various kinds of presses from split-sphere or cubic, all to achieve an even greater pressure and temperature. Among the many benefits of HPHT diamonds are their many colors and are more affordable compared to CVD RareCarat diamonds.
- CVD (Chemical Vapor Deposition): discovered in the 1970s by Soviet scientists. CVD uses a vacuum chamber to transfer carbon atoms into a diamond seed then they introduce a gas mixture composed of hydrogen and methane into the vacuum chamber, using lasers, the carbon atoms are separated from the gas mixture and form a plasma that can be transformed into a diamond layer. The benefits of CVD Rare Carat diamonds over HPHT diamonds, they can be created in lower extreme conditions with higher purity, fewer defections or inclusions, and are of higher quality.
- Detonation Synthetic: simply explained, this method uses specific explosives to create diamonds that are only a few nanometers in diameter. Inside a closed chamber, a mixture of carbon-containing chemical compounds such as RDX or TNT is detonated and sends out a shock wave that compresses and heats the carbon compound in turn creates nanodiamonds. Take note through this method, one can create large amounts of nanodiamonds but they are not for jewellery but rather for other applications such as electronics, optics, medicine, coatings, etc.
How Synthetic Diamonds Are Used in Various Fields
Similar to natural Rare Carat diamonds, lab-grown diamonds are just as sharp and durable. Synthetic diamonds have been used as part of ceramics, glass, metals, and even stone. They are excellent for coating tools even increasing the lifespan and performance of machinery.
Heat Sinks Marketplace
Because of their great high thermal conductivity, lab diamonds are being used as part of heat sinks, they are fantastic for dissipating the heat from hot spots from certain electric devices such as computers, smartphones, and even LED lights. Not only increasing their efficiency but their lifespan as well.
Not only are lab Rare Carat diamonds fantastic conductors of heat but they also make for fantastic electronic components such as sensors, detectors, diodes, switches, and even transistors due to their low dielectric constant, high carrier mobility, and wide band gap. Synthetic diamonds can even be used for qubits and nanowires which are quantum devices.
Yes, optics from prisms, mirrors, lenses, windows, LEDS, photonic crystals, and even lasers. This is because of the high optical transparency of synthetic diamonds which helps transmit light sources with absorption or distortion.
Lab Rare Carat Diamonds maintain the same high-quality characteristics as natural diamonds except lab diamonds only cost a fraction of a natural diamond. Available in multiple colors, shapes, clarity, etc. They can be made into rings, bracelets, pendants, necklaces, earrings, and more.
Rare Carat Moissanite
Buy Rare Carat diamonds. Made from silicon carbine, a Moissanite diamond is an example of how beautiful a lab diamond can be. Tough, brilliant, and full of fire. Moissanite diamonds come in various shapes, often available colorless but one desires a tint of green, yellow, or even gray. This is all possible. Eco-friendly and conflict-free, moissanite is a gemstone worth purchasing.
The Financial Opportunities and Challenges of Laboratory-Grown Diamonds
Without question, there is a growing demand for lab Rare Carat diamonds. Not just because they are more affordable but because they maintain the same high-quality characteristics that make diamonds so desirable. However, throughout the years, lab diamonds have struggled to be recognized as a viable alternative to natural diamonds.
Introductions of official supply chains of lab diamonds have been relatively slow compared to natural diamonds, especially in terms of identification and certification of lab diamonds which have often led to first-time buyers, experiencing mixed receptions or even misrepresentation. As well as, throughout the years, the price of lab diamonds was never stable as they were influenced by the demand and operational costs until now.
Rare Carat Diamonds is proud to say, that throughout its history, has been at the forefront of many innovations in the diamond industry such as being the very first one to introduce an Artificial Intelligence for the diamond industry called Rocky Ai. Countless reviews prove why Rare Carat is America’s #1 diamond marketplace for unbiased and expert advice.
Rare Carat Daimonds’ online platform offers consumers the ability, no, the power to choose which diamond they want specifically from price, quality, cut, color, shape, and so much more.
