A natural 1ct Fancy Vivid Pink diamond: $200,000-500,000
A lab-grown 1ct Fancy Vivid Pink: $2,000-4,000
That's a 99% price difference.
How Colored Lab-Grown Diamonds Are Made
Color is created by introducing specific elements during growth:
- Blue: Boron (same as natural blue diamonds)
- Yellow: Nitrogen (same as natural yellow diamonds)
- Pink: Post-growth treatment (HPHT annealing)
- Green: Irradiation + annealing
The Market Opportunity
Colored lab-grown diamonds are growing 40% annually because:
- Millennials/Gen Z love unique, non-traditional engagement rings
- Fashion jewelry brands (Pandora, Swarovski) are entering the market
- Celebrities are wearing them (reducing stigma)
The Quality Issue
Not all colored lab-grown diamonds are created equal:
- Good: Vivid, saturated color with no secondary hues
- Bad: Pale, grayish, or brownish tones
IGI grades colored diamonds on a scale: Faint → Light → Fancy → Fancy Intense → Fancy Vivid
Only buy Fancy Intense or Fancy Vivid. Anything less looks cheap.
