Are purple lab grown diamonds real diamonds?

Yes. Purple lab grown diamonds are 100% genuine crystallized carbon diamonds with identical chemical, physical, and optical properties to natural mined diamonds.

How much do purple lab grown diamonds cost in 2026?

Direct from our Surat factory, a certified 1 carat purple lab diamond costs $490-$760 USD, 2 carat costs $980-$1,550 USD, and 3 carat costs $1,850-$2,850 USD.

Will the purple color ever fade or change with time?

No. The color is permanently locked inside the carbon crystal lattice and will never fade with light exposure, heat, or jewelry cleaning.

Q: What causes the purple color in lab grown diamonds?

The color is generated by atomic crystal lattice deformation and nitrogen-vacancy optical centers that selectively absorb green and yellow light wavelengths.

Displaying enchanting shades of lavender, violet, and deep imperial plum, genuine purple lab grown diamonds are among the most captivating fancy colored gems in contemporary fine jewelry. Synthesized through precise crystal lattice deformation and controlled post-growth thermal treatment in Surat, our certified purple lab created diamonds offer 100% permanent royal saturation at direct manufacturer prices.

✦ Advanced Gemological Science ✦

How Are Purple Lab Grown Diamonds Created?

Natural purple diamonds are exceedingly rare geological miracles, discovered in tiny quantities in regions like Siberia or the Argyle mine. Their royal violet color results from extreme plastic deformation within the carbon crystal lattice combined with trace hydrogen or nitrogen-vacancy defects.

In our Surat diamond synthesis lab, we recreate this phenomenon with high scientific fidelity. Starting from ultra-pure Type IIa CVD diamond seeds, controlled crystal shear strains and calibrated post-growth thermal treatment create stable atomic color centers. These centers absorb yellow and green light, leaving breathtaking royal purple and violet transmissions.

Frequently Asked Questions

Key facts and guidance about purchasing certified purple lab created diamonds.

Yes. Purple lab grown diamonds are 100% genuine diamonds consisting of crystallized carbon. They possess identical chemical composition, crystalline structure, dispersion, and extreme hardness (Mohs 10) as natural mined diamonds. They will test positive on diamond testers and include certified IGI grading reports.

The purple and violet color arises from atomic crystal lattice deformation and nitrogen-vacancy optical centers that selectively absorb green and yellow light spectrums. This produces rich violet, lilac, and orchid transmissions. This color is structural, uniform, and completely permanent.

Direct from our Surat factory, a certified 1 carat purple lab grown diamond costs between $490 and $760 USD, a 2 carat diamond costs $980 to $1,550 USD, and a 3 carat collector stone costs $1,850 to $2,850 USD. This compares to $40,000 to over $120,000 for mined purple diamonds of equivalent saturation.

While amethyst is quartz (Mohs 7) and purple sapphire is corundum (Mohs 9), a purple diamond is crystallized carbon with the highest possible hardness (Mohs 10) and unmatched optical brilliance (refractive index 2.42 vs 1.77 for sapphire and 1.54 for amethyst), delivering explosive fire that gemstones cannot match.

No. Because the color originates from stable atomic defects locked within the carbon crystal lattice, it will never fade, alter with UV exposure, or degrade with ultrasonic cleaning or steam treatments. It is permanent for generations.
