This 2.57ct lab-grown radiant sits in the two to three carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG759504178 or 759504178. Listed at 12 retailers as of October 30, 2026, with prices from $2,007 to $9,984, a $7,977 spread on the same certified stone. Do Amore Diamonds lists it at $9,984. 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.
