About this 1.55ct lab-grown radiant diamond

This 1.55ct lab-grown radiant sits in the one-and-a-half to two carat band, graded D colour (colourless) and VVS1 clarity (very-very-slightly-included) and certified by IGI LG843682650 or 843682650. Listed at 24 retailers as of November 1, 2026, with a 405% 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.
