This 3.17ct 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 LG744514209 or 744514209. Listed at 17 retailers as of October 27, 2026, with prices from $1,154 to $10,250, a $9,096 spread on the same certified stone. Do Amore Diamonds lists it at $10,250. 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.
