About this 4.48ct lab-grown radiant diamond

This 4.48ct 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 1538619228. Listed at 15 retailers as of November 1, 2026, with prices from £6,131 to £18,325, a £12,194 spread on the same certified stone. Novita Diamonds lists it at £18,325. 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.
