Lab-Grown Diamonds

We’ve become one of Buffalo’s largest diamond centers, now we’re excited to enter the new and exciting frontier of lab-grown diamonds.

Why Lab-Grown?

What is a Lab-Grown Diamond?

Make no mistake about it, a lab grown diamond is not fake, it's not synthetic, and its not CZ. Customers ask us all the time, "Is a lab grown diamond real?" The resounding answer is yes they are! The only thing separating a lab-grown diamond and a mined diamond is how they're created. Mined diamonds are created naturally in the earth's crust after pure carbon is crystallized under intense heat and pressure. Our lab-grown diamonds are created in a laboratory after pure carbon is crystallized using high-energy lasers. They are as brilliant and as hard as mined diamonds, because they are a diamond. In fact, an Andrews Jewelers lab-grown diamond cannot be told from a mined diamond by a gemologist, unless they use sophisticated equipment to scan the makeup and arrangement of its atoms. Lab-grown diamonds are optically, physically, and chemically the same as mined diamonds. They are graded using the same GIA grading system used to assess color, clarity, and cut grades.

How Are Natural Diamonds Formed?

Natural diamonds are created in the Earth’s crust after diamond crystals are subjected to extreme amounts of pressure for millions of years. The diamonds are trapped inside of igneous ore called Kimberlite, then Volcanic eruptions force the diamonds up through narrow shafts.

The kimberlite is mined, and the diamonds are extracted through a mechanical process to reveal the rough material known as octahedron. The rough material is then cut, sawn and carefully polished to produce gem-quality diamonds.

How Are Lab Diamonds Made?

CVD otherwise known as Chemical Vapor Deposition is the newest form of diamond growing. Here the diamond growth takes place inside a vacuum chamber filled with gases rich in carbon, usually methane. The methane cloud is riddled with carbon and then shot with a high-powered microwave beam.

Once a chemical reaction occurs, the diamond seed crystals begin to form on the plate. After several weeks, the rough diamond material is formed. Finally, the rough lab-grown diamond is cut and polished in the same manner as a mined diamond.
