About this 4.42ct lab-grown radiant diamond

This 4.42ct lab-grown radiant sits in the three to five carat band, graded D 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 2527205591. Listed at 16 retailers as of October 28, 2026, with prices from £6,003 to £18,052, a £12,049 spread on the same certified stone. Novita Diamonds lists it at £18,052. 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.
