About this 3.91ct lab-grown radiant diamond

This 3.91ct lab-grown radiant sits in the three to five carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included) and certified by IGI. Listed at a single retailer as of October 30, 2026. If it later appears at another store, Carat Hunter will surface the price comparison automatically. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
