This 1ct lab-grown marquise sits in the classic one-carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG447073861 or 447073861. Listed at 6 retailers as of October 29, 2026, with prices from $922 to $2,615, a $1,693 spread on the same certified stone. MOH London lists it at $2,615. 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.
