Colored lab-grown diamonds have entered the jewelry market as eye-catching, ethical, and affordable alternatives to natural fancy-colored diamonds. But with their dazzling hues and lower price points, many buyers still ask: Are they really worth it? This blog explores the science, beauty, and value of colored lab diamonds, and helps you decide if they’re the right choice for your next piece of jewelry.
What Are Colored Lab-Grown Diamonds?
Colored lab-grown diamonds are chemically identical to mined diamonds but are created in a laboratory environment. Their vivid colors—ranging from pink and blue to yellow and green—are achieved through precise manipulation of trace elements during the growth process or through post-growth treatments.
There are two main methods of production:
- High Pressure High Temperature (HPHT): Often used to create yellow, blue, or green tones.
- Chemical Vapor Deposition (CVD): Typically produces colorless or near-colorless diamonds, but can also be used for pink and blue with additional treatment.
Why Choose a Colored Lab-Grown Diamond?
1. Affordability
One of the most compelling reasons to choose lab-created colored diamonds is the cost. A naturally occurring pink or blue diamond can cost hundreds of thousands of dollars per carat. Lab-grown versions offer similar beauty at a fraction of the price.
| Diamond Type | Carat | Price Estimate |
|---|---|---|
| Natural Pink Diamond | 1.00 | $100,000+ |
| Lab-Grown Pink Diamond | 1.00 | $2,000 – $4,000 |
2. Ethical Sourcing
Colored lab diamonds are produced without the environmental destruction and ethical concerns associated with mining. No ecosystems are disturbed, and no communities are exploited.

3. Customizable Colors
Because lab conditions can be tightly controlled, customers can often choose from a wide spectrum of shades and intensities—something rarely possible with mined stones.
Popular colors include:
- Pink: Romantic and unique
- Blue: Bold and sophisticated
- Yellow: Bright and cheerful
- Green: Earthy and rare
- Purple: Regal and distinctive
Are Colored Lab Diamonds Real Diamonds?
Yes. Lab-grown diamonds are 100% real diamonds with the same carbon structure as natural ones. The only difference is their origin.
They are certified by the same gemological labs (such as IGI or GIA) and graded using the same standards—cut, color, clarity, and carat (4Cs).
Are They Durable Enough for Everyday Wear?
Absolutely. Lab diamonds rank 10/10 on the Mohs hardness scale, just like natural diamonds. They are resistant to scratches and suitable for engagement rings, wedding bands, and other daily jewelry.
In fact, colored lab-grown diamonds offer an opportunity to showcase your personality while maintaining the practicality and resilience of traditional diamonds.
How Are Colored Diamonds Made in Labs?
HPHT Color Creation:
- Yellow and Orange: Achieved by adding nitrogen.
- Blue: Created by adding boron.
- Green: Occurs when diamonds are exposed to radiation.
CVD with Post-Growth Treatments:
- Pink and Purple: Typically created through post-growth high-temperature annealing.
- Multicolor: Some diamonds undergo multiple treatments to produce gradient effects.
These methods allow for repeatable, reliable colors with minimal variation—ideal for designers and buyers alike.
Colored Lab Diamonds vs Colored Moissanite
While colored moissanite may also offer affordability and sparkle, they differ significantly in composition and value.
| Feature | Colored Lab Diamond | Colored Moissanite |
|---|---|---|
| Composition | Carbon | Silicon Carbide |
| Hardness | 10/10 | 9.25/10 |
| Resale Value | Higher | Lower |
| Brilliance | Natural | Rainbow (some find it too flashy) |
| Certification | GIA/IGI | Rarely certified |

Do They Hold Resale Value?
Like most modern diamonds, lab-grown diamonds (especially colored) have a lower resale value compared to natural stones. However, they are not usually purchased as investments, but as affordable, ethical, and beautiful jewelry options.
Some buyers even see them as heirlooms with intention, rather than speculative assets.
Are They Worth It for Engagement Rings?
Yes—especially for couples looking for something unique and meaningful.
Benefits include:
- Color symbolism (e.g., pink = love, blue = loyalty)
- Affordable statement rings
- Gender-neutral fashion options
- Great for second engagement rings or anniversary upgrades
