About this 1.23ct lab-grown radiant diamond

This 1.23ct lab-grown radiant sits in the classic one-carat band, graded D colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG669470408 or 669470408. Listed at 21 retailers as of October 30, 2026, with a 381% 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.
