This 3.19ct lab-grown radiant sits in the three to five carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG754594349 or 754594349. Listed at 17 retailers as of October 30, 2026, with prices from $1,125 to $9,990, a $8,865 spread on the same certified stone. Do Amore Diamonds lists it at $9,990. 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.
