CVD Diamonds
A diamond carat size chart shows the relationship between carat weight and diamond dimensions in millimeters (mm). It helps visualize diamond sizes and understand how cut affects appearance and brilliance.
How Are CVD Diamonds Made?
The CVD diamond growing process is relatively slow compared to other laboratory diamond growing processes, as the molecules move at a speed of around 0.1-10 microns, attaching themselves and forming a diamond film in almost an hour. Due to this method’s slow processing, mimicking or copying the authentic and natural way of diamond formation is hectic. Accordingly, it takes 4 weeks to grow a single crystal diamond using a diamond seed.
In CVD of diamonds,
- A fragile seed is placed in a sealed chamber. The seed is often composed of deposit materials of carbon, fluorocarbons, silicon, filaments, etc.
- The seed is subjected to high temperatures estimated at around 800 degrees Celsius.
- A carbon-rich gas, usually a combination of natural and methane gases, is introduced inside the chamber. Here the carbon particles get ionized and undergo a molecular breakdown, and only the pure carbon particles settle on the diamond seed.
- As the carbon particles combine and build up, a more significant pure carbon component is formed. This newly formed component is identical to a naturally mined diamond in physical, chemical, and optical properties.
What are the benefits of CVD diamonds?
Natural diamonds are rare and adorable, but what if you get better than rare at your price? Yes, you read it right, better than natural diamond.
There are many aspects where CVD diamonds are better than natural diamonds, like purity, price, and environmental effects.
- Only 2% of mined diamonds are considered the purest diamonds with no inclusions and dirt, but all CVD synthetic diamonds are II A type, which means they have no impurities.
- Don’t ever think that high price leads to better things because sometimes the best diamonds come at the least expense. That’s what happens with CVD diamonds; they cost ¼ times less than natural diamonds.
- Are you guessing that natural diamonds, whose name itself includes nature will never harm the environment? Then maybe you are misguided. CVD diamonds are eco-friendly, while mined diamonds are not.
Through this, you may be interest in knowing more about the price of CVD diamonds. That’s what our next topic explained.
Are all lab grown diamonds CVD Diamonds?
Diamonds that are grown in laboratories are synthesized using a variety of techniques. CVD or Chemical Vapor Deposition is one of the ways through which laboratories manufacture diamonds. Traditionally, HPHT was the method through which researchers found that diamonds could be synthesized with the help of a diamond anvil.
CVD is comparatively a new method that evolved in the decades following the 1980s. Since then, manufacturing laboratory diamonds has been a relatively popular way to avoid exhaustive resources and rigorous machinery. Even though CVD consumes an elaborate procedure followed by a considerable time, it is still better preferred by lab diamond companies, Finegrown Diamonds itself included.
Other methods apart from the HPHT process and CVD are reasonably new to the diamond industry and almost less used by any manufacturing unit.
How To Clean CVD Diamonds?
Since diamonds are one of the most durable substances on earth, that doesn’t mean they do not need maintenance. Diamond and diamond jewelry requires some care and cleaning to sustain their quality and spark.
- Where you put a diamond is most important. Always keep your CVD diamond in a given box or zip lock bag to keep it safe from any unpredictable accident.
- Periodic professional cleaning can make your diamond shine more.
- Try not to use the ultrasonic cleaner as much as possible, as it will harm the metal of your jewelry; hence the chances of losing your diamond will increase.
- Permanently remove your jewelry before going for any heavy household cleaning or sports activities.
Wear your jewelry after applying your skin product to keep your jewelry safe from any external chemicals.
CVD Diamonds Price
The price is relatively low compared to mined diamonds. The reason is not so straightforward, natural diamonds are mined, and it’s associated with colossal mining costs and hence exceedingly pricey; only one of the reasons. To extract a single diamond from the depths of the earth’s mantle requires a load of human and material resources. This exhausts the resources and leads to a substantial ecological loss. On the other hand, CVD diamonds are produced with the help of technology and pure carbon atoms devoiding chemical impurities. (carbon is an element present in everything in and around us).
Buy CVD-based lab grown diamond or colored lab grown from a trusted manufacturer and wholesaler company like finegrown diamond. Finegrown Diamonds is also one of the certification providers; finegrown diamonds can directly sell its diamonds to customers with the best offer and trusted shipping partner. And ordinary people get relief from paying extra to the double-dealing and mid-man.
Lab grown CVD diamonds are almost 20% to 40% cheaper than their natural counterparts of the same grade;
Diamond Type | Cut | Clarity | Color | Carat | Price |
Natural diamond | Princess cut | SI | G | 1.00 | 4133$ |
Lab grown CVD diamond | Princess cut | SI | G | 1.00 | 1094$ |
CVD diamonds are thus, not only eco-friendly and sustainable but also economical. Switching to CVD diamonds is a wise decision and a step towards a changed attitude concerning our planet and its sustainable future. You can buy a near-colourless CVD lab diamond for the price of a lower-colored (I, J, K) colored earth mined diamond.
Inquiry CVD Diamond
The authenticity of CVD diamonds
CVD diamonds are man-made in laboratories under controlled conditions and temperatures. Hence, it is often assumed that they would turn out to be looking flawless, devoid of inclusions, and picture-perfect. However, that is not the case.
Since CVD diamonds require the same production process as one involved in the formation of natural diamonds, they are not perfect in appearance and structure and may have chemical impurities. The lab growing diamond also has certain imperfections similar to those found in natural diamonds. On the brighter side, this makes them more similar to natural diamonds. The inclusions in a diamond are natural and, preferably, make each diamond different from its counterparts.
After CVD lab diamonds have been manufactured in the Laboratory, they undergo the same cutting and polishing process as followed for natural diamonds. Their imperfections are removed or reduced to the nearest possible extent. If the imperfection is on the table or edges, it can easily be removed, but if the flaw is inside, then it is inclusive of the diamond.
The clarity, cut, color, and carat of the CVD diamond is measured and properly certified by professionally qualified diamond certification laboratories like IGI, GIA, and AGS to protect the diamond’s authenticity, keeping its real value intact.
