This 1.21ct lab-grown radiant sits in the classic one-carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG846667340 or 846667340. Listed at 17 retailers as of October 30, 2026, with prices from $317 to $1,996, a $1,680 spread on the same certified stone. Reve Diamonds lists it at $1,996. 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.
