This 1.2ct lab-grown marquise sits in the classic one-carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG836626484 or 836626484. Listed at 11 retailers as of October 30, 2026, with prices from $209 to $1,154, a $945 spread on the same certified stone. Reve Diamonds lists it at $1,154. 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.
