About this 1.28ct lab-grown radiant diamond

This 1.28ct lab-grown radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG683533934 or 683533934. Listed at 9 retailers as of October 26, 2026, with a 450% 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.
