About this 0.7ct lab-grown radiant diamond

This 0.7ct lab-grown radiant sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless) and certified by IGI. Listed at 6 retailers as of November 1, 2026, with a 298% 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.
