This 5.03ct lab-grown radiant sits in the over five carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG762544370 or 762544370. Listed at 14 retailers as of October 31, 2026, with prices from $7,707 to $32,852, a $25,145 spread on the same certified stone. Taylor and Hart lists it at $32,852. 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.
