Can A Jeweler Tell The Difference Between Lab Grown Diamonds?

Diamonds, the very name conjures images of luxury, romance, and timeless beauty. These sparkling gems have been cherished for centuries, holding stories of the Earth's deep secrets. With innovation in technology, we've witnessed the introduction of lab-grown diamonds. But can professionals at places like Vivian Jewelers tell the difference between these and their natural counterparts? Let's delve into this shimmering debate.

Understanding Lab-Grown Diamonds

Lab-grown diamonds, as the name suggests, are diamonds cultivated in controlled laboratory environments. They possess the same physical, chemical, and optical characteristics as natural diamonds. However, there are:

Distinct creation processes for lab-grown diamonds, primarily High-Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD).

Ethical benefits, as they steer clear from the conflict zones and detrimental mining practices associated with some natural diamonds.

A reduced carbon footprint, making them an eco-friendly choice.

The Jeweler's Perspective

Even for seasoned professionals, telling the difference between lab-grown and natural diamonds can be a challenge. Traditionally, jewelers rely on:

  • Magnification to spot minute inclusions or imperfections.
  • Tools like a loupe or microscope for a closer look.

Modern Techniques & Technology

However, with lab-grown diamonds evolving in quality, jewelers now employ advanced techniques:

  • FTIR Spectrometry: This detects minor differences in the diamond's formation.
  • UV Fluorescence: Lab-grown diamonds might exhibit a unique glow under UV light.
  • Laser Inscriptions: Some lab-grown diamonds come with microscopic inscriptions, indicating their origin.

Expert Opinions

Several seasoned jewelers confess that without specialized equipment, differentiating becomes challenging. Yet, they emphasize that both diamonds, whether from the depths of the Earth or a pristine lab, are genuine and beautiful in their own right.

Factors That Affect the Differentiability

  • Lab-grown diamond type: The method of creation, HPHT vs. CVD, can give varied characteristics.
  • Size and Cut: The larger the diamond, the more challenging it can be to discern its origin based on inclusions alone.
  • Jeweler's experience: Naturally, the expertise of a jeweler plays a role. At Vivian Jewelers, our team undergoes rigorous training to ensure top-notch evaluations.
