If you’re planning to get married and want to surprise your spouse with an engagement ring, consider using a CVD diamond engagement ring rather than the more traditional diamond options like cut or clarity grade. The difference between the two can be substantial and should not be overlooked when selecting your engagement ring. Let’s take a look at what makes CVD diamonds unique to determine whether they are right for you.
Synthetic diamonds are created when carbon atoms are heated to extreme temperatures under pressure. The first lab grown diamonds were produced by Russian scientists in the 1950s, but it wasn’t until about two decades ago that scientists figured out how to produce large crystals. Modern labs use something called chemical vapor deposition (CVD) to turn carbon from a gas into a diamond. This involves pumping methane, hydrogen and a catalyst—an iron-based powder—into an oven at more than 2,500 degrees Fahrenheit.
These gases mix with methane and oxygen and rise through filters before collecting on horizontal carbon rods within chambers, where they cool and crystallize into diamonds over several weeks. Companies like Chatham use these same techniques to create their lab grown diamond growers. It takes about three months for a synthetic stone to form and once it does, Chatham cuts it into finished stones using traditional diamond cutting tools like saws and polishers. A typical lab grown stone can take anywhere from four days to six months to grow depending on its size. Each one costs less than $10,000 per carat, making them significantly cheaper than mined diamonds. Lab grown stones also have fewer imperfections because they’re manmade rather than natural products of nature; each one is uniform in color and clarity.
Prepping The Diamond.
Before a lab-grown CVD diamond can be created, scientists must first use hydrothermal synthesis to create a seed. This takes place in an autoclave an enormous pressure cooker used for synthesizing substances. The seeds are then sent to a growth chamber where they are placed under high heat and high pressure until they form carbon crystals. These crystals ultimately grow into diamonds. It’s important to note that not all lab-grown diamonds are created equal; depending on how much time and money you want to spend, you can buy either a small or large stone. For example, if you’re looking for something big (i.e., over 10 carats), expect to pay upwards of $10,000 per carat—not exactly pocket change! However, if you’re just looking for a little bling, it might only cost around $1 per carat.
To determine whether your lab-grown diamond is real or fake, experts recommend taking it to a gemologist who has experience with CVD diamonds. You should also take along your receipt so that they can verify when and where your stone was grown.
Introduction To Polishing.
In today’s market, we are seeing more and more CVD diamonds hitting store shelves. These lab-grown gems have become exceptionally popular with buyers in recent years because they offer identical physical properties to mined diamonds but at a significantly lower cost. So how exactly do lab created diamond manufacturer come to life? Let’s take a look! The first step in growing a lab-created diamond is to start with a tiny seed that has been coated in pure carbon—this seed acts as a kind of blank canvas for your new gemstone.
Next, you place your seed into an oven (in liquid form) and heat it to temperatures well over 3,000 degrees Fahrenheit. As your seed begins to melt away, it forms an ultra-thin layer on top of its new base material—and voila! You now have a rough diamond ready for polishing. To polish your rough stone, you will use progressively finer grits of sandpaper or other abrasives until it reaches its final shape and size. This entire process typically takes several weeks or months to complete, depending on whether or not you choose to hire outside help or tackle everything yourself from start to finish.
