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 very-good cut grade and certified by IGI LG744522303 or 744522303. Listed at 14 retailers as of October 30, 2026, with prices from $225 to $2,165, a $1,940 spread on the same certified stone. Do Amore Diamonds lists it at $2,165. 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.
