About this 3.89ct lab-grown radiant diamond

This 3.89ct lab-grown radiant sits in the three to five carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG790694999 or 790694999. Listed at 21 retailers as of October 27, 2026, with a 467% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. 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.
