Why Lab-Grown Diamonds Are a Good Choice

Lab-grown diamonds offer a lot of benefits – environmental responsibility, ethical sourcing, and affordability – making them an increasingly popular choice.

Environmentally, they require significantly less excavation than mined diamonds, reducing landscape disruption and saving precious natural resources.

Ethically, lab-grown diamonds eliminate the concerns associated with conflict diamonds, ensuring a guilt-free purchase.

From a cost perspective, these diamonds are generally more affordable than their mined counterparts, providing consumers with access to luxury and quality at a reduced price.

This combination of factors puts lab-grown diamonds as a responsible and smart choice for the discerning consumer, and they are becoming more popular especially among the younger generation.

How to Ensure That Your Lab Grown Diamond is Genuine

To ensure the authenticity of a lab-grown diamond, it’s crucial to distinguish it from simulants like moissanite.

While both are visually similar, they differ in composition and properties. One key way to verify a lab-grown diamond’s authenticity is through certifications from reputable gemological institutes like GIA or IGI which is dominating the world of lab-grown diamonds certification.

These certifications provide a detailed analysis of the diamond’s characteristics and confirm its lab-grown origin.

Additionally, seeking professional appraisals from certified gemologists can offer an extra layer of assurance. They use specialized equipment to analyze the diamond’s properties, further confirming its authenticity.

Selecting the 4Cs: Clarity, Color, Cut, and Carat For Lab Created Diamonds

The 4Cs—Color, Clarity, Cut, and Carat—are the globally accepted standards used to assess the quality of a diamond. Each ‘C’ represents a different aspect of the diamond’s characteristics.

We covered in different guides everything you need to know about these 4Cs, and what grade you have to look for in pursuing your diamond, and in a nutshell:

  • Color: Ranging from colorless to light yellow or brown, the less color a diamond has, the higher its grade, when you pick a G color grade, which represents a near-colorless diamond, you can guarantee a grade that offers a good balance between colorlessness and value.
  • Clarity: This measures the amount and visibility of internal ‘inclusions’ and external ‘blemishes.’ SI1 grade and its adjacent VS2 clarity diamonds have minor inclusions that are nearly impossible to see with the naked eye, offering a good balance between purity and value.
  • Cut: The cut determines how well the diamond interacts with light, influencing its sparkle and brilliance. An ‘Excellent’ cut ensures the diamond reflects light efficiently, maximizing its sparkle.
  • Carat: This is the weight of the diamond. Larger diamonds are rarer and thus more valuable, but the best choice also depends on personal preference and budget, balanced with the other 4Cs.

Understanding these four aspects helps in making an informed decision, ensuring you choose a diamond that meets your specific needs and preferences.

Essential Care for Lab-Grown Diamonds

Caring for your lab-grown diamond is similar to maintaining a mined diamond, as they both share the same chemical and physical properties

One was “grown” in 2 weeks in a lab, while the other took billions of years to be formed.

Regular cleaning, safe storage, and avoiding harsh activities are key to preserving the sparkle and beauty of your lab-grown diamond.

  1. Regular Cleaning: Use a solution of mild dish soap and warm water to gently clean your diamond. Use a soft brush to remove any buildup, and then rinse and dry it with a soft, lint-free cloth.
  2. Professional Check-ups: Regular check-ups by a professional jeweler can help ensure the setting remains secure and the diamond is in good condition.
  3. Safe Storage: Store your diamond jewelry separately to avoid scratches from other pieces. Soft fabric-lined jewelry cases or individual pouches are ideal.
  4. Avoiding Damage: Remove your diamond jewelry during harsh activities or when using harsh chemicals. This helps prevent potential physical damage or exposure to substances that could dull its appearance.

By following these simple guidelines, you can help ensure that your lab-grown diamond remains as stunning as the day you bought it.
