About this 1.09ct lab-grown radiant diamond

This 1.09ct lab-grown radiant sits in the classic one-carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG623490081 or 623490081. Listed at 18 retailers as of October 28, 2026, with a 478% 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.
