What You Need to Know About Lab Grown Diamonds
Everyone loves diamonds; their sparkle and beauty make them a rare gem. It needs years for a diamond to form. Over the years, lab-grown diamonds have gained popularity. Here is everything you need to know about lab-created diamonds.
What are lab-created diamonds?
The lab-grown diamonds are created in a lab environment. The diamonds have the same physical, chemical, and properties as natural diamonds. The only difference is just the point of origin. Just like the natural diamonds, lab-created diamonds are made with consideration to the 4cs; clarity, cut, carat weight, and color. They are also available in the same shapes as natural diamonds.
How are they made?
Lab-created diamonds are made using advanced technology, where extreme heat and pressure are used to make them look like a natural diamond. There are two ways in creating lab diamonds. The first method is through high pressure and high temperature. The high pressure mimics that of the natural diamonds. Hydraulic pressure, iron, cobalt flux, and nickel create an excellent environment for the diamond to grow.
The second method for creating lab diamonds is using chemical vapor deposition (CVD). Under this process, the diamond seed is placed in a sealed chamber. The chamber is then heated to high temperatures and filled with methane gas and carbon-rich hydrogen. Through the ionization, the carbon gets broken down and allows the carbon molecules to hold onto the diamond seed. It takes 14 days for a diamond to grow using the CVD process.
How to differentiate natural and lab-grown diamond
It's not easy for consumers to differentiate lab-created and natural diamonds. There are even jewelers who can't tell the difference. Here are ways to differentiate the two.
- Type IIa test — it identifies the purity of carbon that makes the diamond. Out of the four types available, Type IIa is the purest. Most lab-created diamonds are type IIa.
- A radiation test — the test is done using specialized equipment. The lab-created diamonds are put under test to measure the light absorbance across ultraviolet regions.
Benefits of lab-grown diamonds
- Cost — Lab-created diamonds are affordable compared to natural diamonds.
- Characteristics — the lab-grown diamonds have the same optical, physical, and chemical characteristics as natural diamonds.
Should you buy lab-grown diamonds?
Some people don't put a lot of thought into whether a diamond is lab-grown or natural. Lab-grown diamonds have the same look and feel of natural diamonds but at a lower cost. When choosing between natural and lab-grown diamonds, consider your needs and preference. You can also consult your jeweler to help you make the decision.
