A Comprehensive Guide of Lab-Grown Diamonds: Everything You Need to Know

Diamonds have long held a special place in our hearts. They symbolize love, commitment, and the remarkable beauty of nature. However, recent advancements in technology have given rise to a new player in the world of diamonds. This new player is the lab grown diamonds.

These diamonds are creating a buzz in the jewelry industry. This is due to their ethical and environmental advantages. In this guide, we will talk about everything you need to know about lab grown diamonds.

What are Lab Grown Diamonds?

Lab Grown Diamonds have several alternative names. They are called synthetic diamonds, cultured diamonds, man-made diamonds, and much more. These stones are created in a controlled setting, such as a laboratory.

They are not formed deep within the Earth’s mantle over millions of years like natural diamonds. The optical properties, chemical properties, and the physical properties of these two types of diamonds are same. Only their origins and production processes are different.

How Are Lab-Grown Diamonds Made?

There are two main methods implemented for the production of man-made diamonds. They are the HPHT method and the CVD method.

  • High Pressure High Temperature (HPHT)
    In this method, carbon is subjected to extreme heat and pressure. This is done in order to replicate the natural diamond-growing conditions. Carbon is dissolved in a molten metal catalyst, and diamond crystals grow over time.

  • Chemical Vapor Deposition (CVD)

CVD diamonds are created by introducing a carbon-rich gas into a vacuum chamber and using microwave energy to create a plasma ball. The carbon atoms are then deposited layer by layer on a diamond seed.

Why Choose Lab-Grown Diamonds?

There are several reasons why you should buy synthetic diamonds. They range from cost factors to ethical considerations. Read on to know more about them here:

  • Ethical Sourcing

These diamonds are free from the ethical concerns often associated with natural diamond mining. These ethical concerns are related to conflict diamonds, blood diamonds, and unfair labor practices.

  • Environmental Impact

Mining natural diamonds can lead to significant environmental damage. This includes deforestation and habitat destruction. Cultured diamonds, on the other hand, have a smaller carbon footprint. This makes them more environmentally friendly.

  • Cost-Effective Alternative

These diamonds are typically more affordable than their natural counterparts. This allows consumers to purchase larger or higher-quality stones within their budget.

  • Quality and Purity

These diamonds often have fewer impurities and inclusions. This results in a higher clarity grade. This can make them an attractive option for those seeking near-flawless gems.

Characteristics of Lab-Grown Diamonds

  1. Physical Properties: Lab made diamonds have the same hardness, brilliance, and sparkle as natural diamonds. They are rated on the same 4 Cs scale. These 4 Cs include carat weight, cut, color, and clarity.

  1. Variety: Synthetic diamonds come in a wide range of shapes, sizes, and colors. This makes them a versatile choice for jewelry designs. A wide variety of jewelry is created by using these diamonds. This includes necklaces, rings, bracelets, earrings, and more.

  1. Durability: Just like natural diamonds, cultured diamonds are extremely durable. They can last a lifetime. Both these diamonds score a perfect 10 on the Mohs scale. It is a measurement system that rates the hardness of a mineral.

Purchasing Lab-Grown Diamonds

  • People often ask one question: Do synthetic diamonds hold their value? The answer is yes. Lab-grown diamonds often hold their value. However, they are not as costly as natural diamonds. So, if you are buying man-made diamonds as an investment option, consider buying natural diamonds.

  • Certification: When buying cultured diamonds, make sure that you get a proper certification from a reputable gemological laboratory such as the GIA or Gemological Institute of America. This report provides detailed information about the diamond’s 4 Cs. It also provides information on the other characteristics of the diamond.

  • Reputable Retailers: Choose established and reputable jewelers who can provide transparency about the origin of the diamond and offer a variety of lab-grown options.

  • Customization: Cultured diamonds are ideal for customized jewelry. They are available in various shapes and sizes. You can work with a jeweler to create jewelry pieces that are truly unique. Take the help of a jeweler to create a unique piece of jewelry.

Care and Maintenance

Synthetic diamonds require the same care and maintenance as natural diamonds. Clean your diamond jewelry regularly with a mild detergent and make sure that you use a soft brush. Also, it is important to avoid exposing them to harsh chemicals or abrasive materials.

Are Lab Grown Diamonds GIA Certified?

According to reports, GIA has been grading synthetic diamonds since 2007. However, the reports that GIA created for these diamonds were highly different from the reports they created for the mined diamonds. The GIA initially provided a full grading report for natural diamonds.

When it came to lab diamonds, they graded only the color and clarity range. This made it difficult for the companies to price the lab-grown diamonds for consumers. However, reportedly, a new policy change was announced. The GIA will be offering an online-only color and clarity grading for lab diamonds.
