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 very-good cut grade and certified by IGI LG761559333 or 761559333. Listed at 15 retailers as of November 2, 2026, with a 449% 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.
