About this 3.18ct lab-grown radiant diamond

This 3.18ct lab-grown radiant sits in the three to five carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2537650853. Listed at 13 retailers as of October 28, 2026, with a 159% 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.
