This 1.2ct lab-grown radiant sits in the classic one-carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG616402701 or 616402701. Listed at 13 retailers as of October 27, 2026, with prices from $152 to $1,460, a $1,308 spread on the same certified stone. Do Amore Diamonds lists it at $1,460. 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.
