What to Know When Purchasing Lab Grown Diamonds

Oct 5, 2023


Have you thought about lab-grown diamonds? They’re chemically identical to mined diamonds, but are created in labs and not extracted from the earth.

They’re just as beautiful, and better yet, they’re environmentally friendly. With lab-grown diamonds, you’re not just getting a stunning gem, you’re also reducing your carbon footprint.

Let’s dive into what you need to know when purchasing these sustainable sparklers.

Understanding the Role of GIA

When you’re considering a purchase of lab-grown diamonds, one integral factor you should understand is the role of the Gemological Institute of America (GIA). This reputable organization provides certification for these gems, ensuring their authenticity and quality.

Just like their mined counterparts, lab-grown diamonds are graded based on the same criteria – color, clarity, cut, and carat weight. The GIA assigns these diamonds a unique identification number, which you can use to verify the grading report. These reports also include information about the diamond’s production and origin.

Comparing Lab-Grown and Mined Diamonds

How do lab-grown diamonds compare to their mined counterparts?

Both types are chemically and physically identical. Without high-tech equipment, you can’t distinguish between them.

However, lab-grown diamonds offer a reduced carbon footprint, thanks to environmentally conscious practices. They’re created using the Chemical Vapour Deposition process, whereas mined diamonds form deep within the earth’s mantle, naturally over billions of years.

Grading criteria remain the same for both types, considering the 4Cs: color, clarity, cut, and carat weight. However, lab-grown diamonds come with a unique identification number and laser-inscribed origin.

Mined diamonds also offer a variety of fancy colors. Nevertheless, the choice boils down to personal preference.

Both options provide captivating sparkle and durability.

The Process of Creating Lab-Grown Diamonds

In light of understanding the comparison between lab-grown and mined diamonds, let’s now delve into the fascinating process of creating lab-grown diamonds. You might be surprised to learn that these diamonds are created using a technique known as Chemical Vapour Deposition (CVD).

Here’s how it works: diamond seeds are placed in a low-pressure chamber. Then, hydrogen and methane gases are injected into the chamber. High-power microwave energy is applied, heating the chamber. The heat breaks down the gases, releasing carbon atoms.

These carbon atoms then ‘rain down’ onto the diamond seeds, layering them atom-by-atom. Over time, this process grows a diamond. It’s a high-tech, precision process that produces diamonds identical to those formed in Earth’s mantle.

Insight Into Mined Diamonds

Understanding mined diamonds, you’ll find that these precious gems are incredibly old, often around 2.3 billion years, and are formed deep within the earth’s mantle under immense heat and pressure. This intense process results in a variety of beautiful colors, making each diamond unique.

Mined diamonds are extracted from the earth in an operation that’s both labor-intensive and environmentally impactful. They’re removed from volcanic pipes, the geological structures that transport them from their fiery birthplace to the earth’s surface.

You should also know that each mined diamond is distinct. They’re graded on their color, clarity, cut, and carat weight – the Four Cs. Despite their beauty and allure, it’s vital to consider their environmental impact when choosing between mined and lab-grown diamonds.

Verifying Lab-Grown Diamonds

When you’re looking to buy a lab-grown diamond, it’s crucial to check out its verification process. Independent third-party grading organizations authenticate these gems. They provide grading reports that characterize the diamond based on the 4Cs – color, clarity, cut, and carat weight. These reports also include production dates and origin.

One unique feature is that lab-grown diamonds are laser-inscribed to indicate their origin. This gives you peace of mind about the stone’s legitimacy. You can verify the grading report using the unique identification number provided.
