Lab-grown diamonds have taken the jewelry world by storm with their ethical sourcing, eco-friendly production process, and stunning brilliance - offering an attractive alternative to mined stones. However, one question has lingered for some: Do lab diamonds turn yellow?

This blog post will discuss the science of diamond color, state facts regarding yellowing in lab-grown diamonds, and offer tips to preserve its sparkling beauty for a long!

Understanding the Diamond Grading System

Diamonds are known for their exceptional brilliance and fire, yet color plays an equally essential role when calculating value. To this end, the Gemological Institute of America developed its widely recognized Diamond Color Grading Scale that ranges from D (colorless) to Z (light yellow or brown), where D-F grade stones represent near-perfect transparency - considered amongst the most valuable jewels by collectors worldwide.

Color in diamonds arises from trace impurities incorporated during their formation; nitrogen being one of the more frequently seen culprits that affect its hue. Its concentration has an impactful bearing on how diamonds will look once cut and polished.

Can Lab Diamonds Change Colors?

Lab-grown diamonds do not change color over time as part of normal wear and tear due to being chemically identical to mined stones; lab diamonds offer equal durability and color stability as their counterparts in terms of chemical makeup and durability.

Laboratory diamond production affords us greater control of their impurities, such as nitrogen. This rigorous process guarantees sparkling stones with lasting brilliance for generations.

Note that growth methods like High-Pressure High-Temperature (HPHT) may sometimes result in diamonds with an apparent yellow tint due to nitrogen aggregates present during growth; modern lab diamond producers frequently utilize Chemical Vapor Deposition (CVD), which often yields diamonds with exceptional color clarity achieving D-F grades.

When Yellowing Occurs In Exceptional Cases

Do lab diamonds turn yellow? - While yellowing of mined or lab-grown diamonds is highly unlikely, in certain situations, there could be temporary or permanent color changes:

  • Extreme Heat Exposure: Subjecting diamonds to extremely high temperatures encountered during jewelry repair processes may temporarily discolor them with yellow hues that typically dissipate upon cooling the stone back down.
  • Crystal Structure Defects: While rare, diamonds might sometimes contain inherent crystal structure defects that lead to yellowing over time. Reputable diamond growers employ stringent quality control measures to stop such diamonds from reaching the market.

Keep Your Diamond Sparkling

Daily wear and tear can result in buildups of dirt and grime on diamonds, leaving them looking dull or yellowish in appearance. Restoring its brilliance requires only regular cleaning with the mild soap solution and soft brush for best results - simply clean away!
