About this 4.05ct lab-grown radiant diamond

This 4.05ct lab-grown radiant sits in the three to five carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG754595262 or 754595262. Listed at 29 retailers as of October 30, 2026, with prices from $4,553 to $20,602, a $16,049 spread on the same certified stone. With Clarity lists it at $20,602. 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.
