About this 3.03ct lab-grown radiant diamond

This 3.03ct 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 and certified by IGI LG627418680 or 627418680. Listed at 22 retailers as of October 29, 2026, with prices from $1,223 to $8,752, a $7,529 spread on the same certified stone. Diamond Quarter lists it at $8,752. 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.
