About this 1.29ct lab-grown radiant diamond

This 1.29ct lab-grown radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG675511885 or 675511885. Listed at 20 retailers as of October 29, 2026, with a 400% 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.
