Do Lab Grown Diamonds Change Color?
Lab grown diamonds have gained popularity for their brilliance, affordability, and ethical sourcing. However, a common question among buyers is whether these diamonds can change color over time. To address this concern, it’s important to understand what lab grown diamonds are, their physical properties, and the factors that might influence their appearance.
At PHD Jewelers, we’re here to provide clarity, offering expert insight into the science of lab grown diamonds and how they compare to their natural counterparts. Let’s dive deeper into the question of whether lab grown diamonds can change color.
The Myth of Color Changes in Diamonds
One common misconception is that diamonds, especially lab grown ones, can fade or change color over time. This myth likely arises from misunderstandings about diamond grading or confusion with other gemstones that are less stable. Rest assured, lab grown diamonds retain their original color and brilliance indefinitely.
What Are Lab Grown Diamonds?
Lab grown diamonds are authentic diamonds created in a controlled environment using advanced technology. They share the same chemical composition, physical properties, and optical brilliance as mined diamonds, making them indistinguishable to the naked eye.
How Are Lab Grown Diamonds Made?
Two primary methods are used to create lab grown diamonds:
- High-Pressure High-Temperature (HPHT): Mimics the intense heat and pressure conditions under which natural diamonds form in the Earth’s mantle.
- Chemical Vapor Deposition (CVD): Involves layering carbon atoms in a vacuum chamber to grow a diamond crystal over time.
Both processes produce diamonds that meet the same rigorous standards as natural diamonds in terms of clarity, cut, and color.
Do Lab Grown Diamonds Change Color Over Time?
The simple answer is no. Lab grown diamonds do not inherently change color over time. They are as stable and durable as natural diamonds, maintaining their color, clarity, and brilliance throughout their lifetime.
Why Lab Grown Diamonds Retain Their Color
- Stable Molecular Structure: Lab grown diamonds are pure carbon, arranged in a crystalline lattice that is impervious to environmental changes.
- Resilience to External Factors: Unlike other gemstones, diamonds (lab grown or natural) are not affected by sunlight, UV exposure, or heat. These environmental factors cannot alter a diamond’s color.
- Consistent Grading: The Gemological Institute of America (GIA) grades lab grown diamonds on the same scale as natural diamonds, ensuring accurate and permanent color classification.
When Might Lab Grown Diamonds Appear to Change Color?
While lab grown diamonds do not change color, certain external factors might temporarily affect how they appear.
1. Dirty or Scratched Surfaces
Over time, oils, dirt, or scratches on the surface of a diamond can affect its brilliance and make it appear dull or discolored.
- Solution: Regular cleaning with warm water, mild detergent, and a soft brush restores the diamond’s natural sparkle.
2. Lighting Conditions
Diamonds can appear to change color under different lighting conditions:
- Fluorescent Lighting: May give a cooler tone.
- Incandescent Lighting: May bring out warm tones. These variations are optical effects, not permanent changes in the diamond itself.
3. Reflection from Metal Settings
The metal surrounding a diamond can influence its perceived color:
- White Metals (Platinum, White Gold): Enhance the diamond’s natural brightness.
- Yellow or Rose Gold: May reflect warm tones onto the diamond, especially in near-colorless stones.
Factors That Guarantee Color Stability
Lab grown diamonds undergo meticulous grading and quality control to ensure they maintain their original beauty. Several factors contribute to their stability:
1. Color Grading
Lab grown diamonds are graded on a strict color scale, from D (completely colorless) to Z (noticeable yellow or brown tones). The color grade assigned during certification does not change over time.
2. Structural Integrity
The crystalline structure of a lab grown diamond is identical to that of a natural diamond, ensuring exceptional durability and resistance to environmental changes.
3. Post-Creation Treatments
Some lab grown diamonds may undergo additional treatments to enhance their color. These treatments are permanent and do not fade or wear off.
How to Keep Your Lab Grown Diamond Looking Its Best
While lab grown diamonds are incredibly durable, proper care ensures they always look their finest.
1. Regular Cleaning
Clean your diamond jewelry every few months using a solution of warm water and mild dish soap. Gently scrub with a soft brush to remove any debris.
2. Professional Maintenance
