Lab Grown Diamonds Are Real Diamonds …without depleting a natural resource. Choosing Lab Grown Diamonds over mined ones offers great value and serves a bigger purpose.

With their guaranteed origins, guilt-free composition, sustainable and efficient growing, Lab Grown Diamonds are socially responsible and environmentally friendly. The manufacturing process reduces carbon emissions by 7 times and uses 85% less water than the production of mined diamonds. Lab Grown Diamonds are 100% composed of carbon and are nitrogen-free. Besides these environmental benefits, Lab Grown Diamonds have greater purity and improved quality, showing off the same sparkles you would look for in natural diamonds.

The range of affordable diamonds in various colors and clarities makes shopping for loose Lab Grown Diamonds and Jewelry pieces attractive for a broad spectrum of customers. These sustainable diamonds have emerged as the new true symbol of love and commitment among consumers who wish to build a brighter future.

World-renowned diamond grading & certifying labs (such as GIA, IGI, and SGL) classify these diamonds as Type IIA. The shine, brightness & luster of Type IIA diamonds is significantly better than any other diamond. As a result, the brilliance of Lab Grown Diamonds is unmatched and rare to find in their mined counterparts.

Lab Grown Diamonds are certified using the exact same process and rating systems as mined diamonds.

All Hana Diamonds are exclusively certified through the Gemological Institute of America (GIA). GIA evaluates our diamonds and assigns values to each of the 4 Cs (Cut, Clarity, Color and Carat) as well as notes any flaws and other notable features. Each of our stones comes with their own original GIA certificate.

How Are Lab Grown Diamonds Made?

Line

Lab Grown Diamonds are produced under the same conditions that mined diamonds experience, the only difference is that the process takes place in a lab rather than deep within the earth. Geology teaches us that most natural diamonds were formed between 1-3 billion years ago. Carbon dioxide trapped beneath the ground was exposed to vast heat and pressure; compacting and rearranging the carbon atoms into the structures we know of as diamonds.

Later, tectonic and volcanic activity shifted these stones around, bringing them closer to the surface where humans could access them.

Today there are two main successful processes in which lab-grown diamonds are produced:
High Pressure – High Temperature (HPHT):

High Pressure Hight Temperature (HPHT) is a method invented in the 1950s where diamonds can be produced from scratch in a controlled environment. This method can also enhance natural diamonds’ color to make them brighter, from a yellowish diamond to a colorless one.

The HPHT method includes the following steps

Chemical Vapor Deposition (CVD):

Created in the 1980s, Chemical Vapor Deposition (CVD) is a more recent diamond growing technique during which a gemstone is grown from a hydrocarbon gas mixture, imitating how diamonds form in interstellar gas clouds.

The CVD method includes the following steps

Both methods can produce high quality lab grown diamonds, with excellent color and clarity.

The safest way to verify if a diamond is CVD or HPHT is to check the original certificate’s comment section. Here it will mention if it is CVD or HPHT, as grown or if there are indications of post-growth treatment.

We at Hana Diamonds offer both, HPHT and CVD - GIA certified Lab Grown Diamonds.
