This 1.21ct lab-grown radiant sits in the classic one-carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG605342045 or 605342045. Listed at 14 retailers as of October 30, 2026, with prices from $278 to $2,389, a $2,111 spread on the same certified stone. Do Amore Diamonds lists it at $2,389. 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.
