About this 1.7ct lab-grown radiant diamond

This 1.7ct lab-grown radiant sits in the one-and-a-half to two carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG623464285 or 623464285. Listed at 20 retailers as of October 25, 2026, with a 386% 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.
