About this 1.23ct lab-grown radiant diamond

This 1.23ct lab-grown radiant sits in the classic one-carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI. Listed at 11 retailers as of October 28, 2026, with a 298% 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.
